2 Welcome to R&S NGL/NGM

The one or two-channel power supply series are based on a classical transformer con-

cept with linear regulators. This concept allows the instrument to achieve highest accu-

racy and lowest residual ripple.

The R&S NGL/NGM power supply series feature galvanically isolated, floating over-

load and short-circuit proof outputs. When multiple channels are connected in parallel,

higher currents can be achieved. When connected in serial, higher voltages are ach-

ievable.

Multi-purpose protection functions are available for each channel which you can set

separately, such as overcurrent protection (OCP), overvoltage protection (OVP) and

overpower protection (OPP). If such a limit is reached, the affected output channel is

automatically turned off and an indicator icon (

, , ) blinks on the display. In the

case of two-channel power supply (NGL202, NGM202), the overcurrent protection can

be linked to the other channel. In this case, the linked channel is turned off when the

other channel reaches a limit.

Additionally, the R&S NGL/NGM is protected with overtemperature protection (OTP).

This safety feature protects the R&S NGL/NGM from overheating. When the tempera-

ture in the power supply exceeds the OTP limit, the channel outputs are automatically

cut off.

The Arbitrary function allows a freely definable voltage and current sequences with a

timeframe as short as 1 ms. It allows varying the voltage or current during a test

sequence, for example to simulate different charging conditions of a battery. With

"Ramp" function, the R&S NGL/NGM provides the operating condition to ramp up the

supply voltage within a defined timeframe of 10 ms to 10 s.

All R&S NGL/NGM power supplies are equipped with a color TFT display (800 pixels x

480 pixels) and enhanced with touch input capability. The R&S NGL/NGM comes with

a USB and LAN (LXI) interface. Equipped with a wireless LAN (WLAN) option, you can

establish a network connection wirelessly.

The digital I/O interface installed at the rear panel is activated with an option, it allows a

single trigger-in signal to control multi trigger-out signals on the power supply, providing

many possibilities to control outputs and associated devices in the event when a trigger

occurs.

The user manual contains description of the functionalities that the instrument pro-

vides. The latest version is available for download at the product homepage (

3.2 Ambient Conditions

The allowed operating temperature ranges from +5 °C to +40 °C (pollution category 2).

The maximum relative humidity (without condensation) is at 80 %.

During storage and transport, the temperature must be between -40 °C and +70 °C. In

case of condensation during transportation or storage, the instrument requires approxi-

mately two hours to dry and reach the appropriate temperature prior to operation. The

instrument is designed for use in a clean and dry indoor environment. Do not operate

with high dust and humidity levels, if danger of explosion exists or with aggressive

chemical agents.

Any operating position may be used; however adequate air circulation must be main-

tained. For continuous operation, a horizontal or inclined position (integrated stand) is

preferable.

Specifications with tolerance data apply after a warm-up period of at least 30 minutes

at a temperature of 23 °C (tolerance -3 °C / + 7 °C).

The heat produced inside the instrument is guided to the exterior via temperature-con-

trolled fan. Each channel has multiple temperature sensors which check the heat gen-

eration in the instrument and control the fan speed.

It is necessary to ensure that there is sufficient space around the instrument sides for

heat exchange. If the temperature inside the instrument increases more than the

Do not obstruct the ventilation holes!

3.3 Measurement Categories

This instrument is designed for supplying power-on circuits that are only indirectly con-

nected to the low voltage mains or not connected at all. The instrument is not intended

for measurements within the measurement categories II, III or IV; the maximum poten-

tial against earth generated by the user must not exceed 250 V peak in this application.

The following information refers solely to user safety. Other aspects, such as the maxi-

mum voltage, are described in the technical data and must also be observed.

The measurement categories refer to transients that are superimposed on the mains

voltage. Transients are short, very fast (steep) current and voltage variations which

may occur periodically and non-periodically. The level of potential transients increases

as the distance to the source of the low voltage installation decreases.

●

Measurement CAT IV: Measurements at the source of the low voltage installations

(e.g. meters)

●

Measurement CAT III: Measurements in building installations (e.g. power distribu-

tion installations, power switches, firmly installed sockets, firmly installed engines

etc.)

●

Measurement CAT II: Measurements on circuits electronically directly connected to

the mains (e.g. household appliances, power tools, etc.)

●

0 (instruments without measured measurement category): Other circuits that are

not connected directly to the mains

3.4 Mains Voltage

The instrument uses 50 Hz / 60 Hz mains voltages ranging from 100 VAC, 115 VAC or

230 VAC (tolerance ± 10 %). Mains voltage must be set correctly by removing the fuse

holder and rotating until the correct voltage appears through the window and reinstal-

ling the fuse holder. The input line fuse is accessible externally. Power socket and fuse

holder form a single unit.

You need to first disconnect the power cord from the connector before you can safely

replace the fuse (as long as the fuse holder is undamaged). Next, the fuse holder must

be pried out using a screwdriver. The starting point is a slot next to the contacts. The

fuse can then be forced out of its mounting and must be replaced with an identical fuse

(see information about the fuse type on the rear panel). The fuse holder is inserted

Source and sink current

The R&S NGL/NGM power supply series are 2 quadrant power supplies which may

both source and sink current. When the voltage across the output terminal exceeds the

set voltage, current flows into the instrument. The default behavior "Auto" can be con-

figured in output menu, see

Chapter 6.2.3.4, "Output Mode", on page 51.

On the display, sink mode is shown as negative current. See also "CR mode"

on page 26.

The R&S NGL/NGM displays the home window.

2. Select voltage or current parameter in the home window.

The R&S NGL/NGM displays an on-screen keypad to set the value.

3. Enter the required value.

4. Confirm value with the unit key (V/mV or A/mA).

See

"Source and sink current" on page 26 for more information on the operating

modes supported in different models.

4.3.2 Activating the Channels Output

The output voltages can be switched on or off regardless of the instrument's operating

mode.

To switch on or off channel output.

1. For the two-channel models, select desired channel key ([Ch1] or [Ch2]) on the

front panel.

2. Press [Output] key.

The R&S NGL/NGM outputs the set voltage level on the output channel terminal.

Depending on the operating mode which the channels are operated in, the following

are observed:

CR mode

CR mode is a special case of sink mode in which the instrument behaves like a con-

stant resistor. Only in this mode, the respective channel keys and display font color in

the home window turns cyan.

In "normal" sink mode, the colors are the same as in source mode: green if the current

flowing into the R&S NGL/NGM is below the set current and red if the current is limited

to the set value. The only visible indication of sink mode is the change of sign of the

current readout to "Minus".

5.5 Operation Modes

The R&S NGL/NGM operates in three different modes, i.e. the constant voltage (CV),

constant current (CC) and constant resistance (CR). The instrument switches automat-

ically between CV and CC depending on the connected load. When CR is

configured,

the instrument is not switched to CR mode automatically, it will operate in CR mode

when sinking but source in CV or CC mode.

CV mode

Figure 5-12 shows that if the instrument is in the range of voltage regulation, the output

voltage V

out

remains constant while the current may increase to its maximum value I

max

when the connected load is increasing. In CV mode, the font text in the channel display

area changes to green.

See

Figure 5-3.

Operating Basics

R&S

NGL200/NGM200

43User Manual 1178.8736.02 ─ 09

If I

out

reaches I

max

, the instrument switches to CC mode, i.e. the output current remains

constant and limited to I

max

even if the load increases. Instead, the output voltage V

out

decreases to almost zero with a short circuit. In CC mode, the font text in the channel

display area changes to red.

See Figure 5-3.

CR mode

To go into CR mode, the R&S NGL/NGM must operate in sink mode where current

flows into the instrument and "Constant Resistance" is enabled.

With "Constant Resistance" enabled and configured, the R&S NGL/NGM can set the

resistance in sink mode, this allows the R&S NGL/NGM to behave like an electronic

load which is useful in battery test application.

In CR mode, the font text in the channel display area changes to cyan.

in developing products whereby battery is not ready for testing, such as phones and

portable devices.

The R&S NGM provides a battery simulator editor to configure the battery model at dif-

ferent states to analyze the products behavior under specific conditions. Different bat-

tery state of charge (SoC) can be simulated rapidly without waiting for the charging or

discharging process of a normal battery when conducting tests.

The battery symbol represents the state of charge.

The light blue bar indicates the open circuit voltage

and the dark blue bar indicates the terminal voltage.

The differences between both bars show the voltage

drops on internal resistance.

Scale: the maximum of both bars are the maximum

defined voltage in the battery model and the mini-

mum is the minimal defined voltage.

See Figure 6-13.

SoC State of charge represents the current battery

capacity, e.g. 85% SoC represents that 15% of bat-

tery capacity is used.

The open circuit voltage, Voc is the voltage between

the battery terminals with no load applied. The Voc

depends on the loaded battery model and the cur-

rent SoC.

The internal resistance, ESR (also known as Equiv-

alent Series Resistance) depends on the loaded

battery model and current SoC.

The terminal voltage, Vt is the voltage between the

battery terminals with applied voltage drop over the

ESR. Terminal voltage varies with charge or dis-

charge current.

Model The loaded battery model applied in the battery sim-

ulator.

Battery capacity The storage capacity for the battery:

●

Minimum value: 1 µAh

●

Maximum value: 100 kAh

Editing a new value here overwrites the current

value loaded from the

battery model editor.

Current limit In addition to the resistance of the battery model,

current flow can be limited to protect possibly sensi-

tive equipment connected to the device.

There are three current limit settings available:

●

SoC < 0 % (the battery is empty)

●

6.6 Trigger / Digital I/O

Digital I/O pins voltage rating

Do not exceed the maximum voltage rating of the Digital I/O pins when supplying vol-

tages to the pins.

The specified voltages are 0 V to 24 V for all output pins and 0 V to 15 V for all input

pins.

For more information, see the instrument datasheet (P/N: 5216.1057.32).

Instrument option

R&S NGL-K103 (P/N: 3652.6385.02) or R&S NGM-K103 (P/N: 3643.9904.02) option is

required for the Digital I/O signals.

Option is not required for "User Button" and "*TRG" trigger-in signals.

With an optional Digital I/O, you can apply a single trigger-in signal and control multiple

trigger-out signals on the instrument. These trigger-out signals can be used to perform

function such as triggering the data logger to record instrument when a channel output

is active or protection event is used to trigger the digital out pin, which in turn can be

used for fuse linking between two instruments.

The trigger system has two latency types: low latency and software latency. While low

latency triggers are executed faster, the software latency does not have additional

requirements.

The low latency actions are highlighted in bold (blue) and required to have same hard-

ware channel for trigger source and trigger target.

The FastLog can write the measurement data (votage/current) either to the USB

device or to a SCPI client. In SCPI mode the client is required to be connected to the

R&S NGM before "FastLog" is enabled

"FastLog" is a much faster data logging for voltage and current measurements. This

fast logging features the benefit to capture short peak changes in voltage and/or cur-

rent measurements which is particular useful in the measuring of low energy device,

e.g. IoT products.

The R&S NGL/NGM displays the on-screen keypad to enter the port number and

hostname.

● "SCPI Raw Port": A port number used to open a raw TCP/IP connection to

send raw SCPI commands to the instrument

● "Hostname": The name assigned to the instrument used to identify it in the net-

work

When the connection is available, the network icon is highlighted in white on the device

status bar information.

6.16.1.1 LAN Connection

The R&S NGL/NGM is equipped with a network interface and can be connected to an

Ethernet LAN (local area network). A LAN connection is necessary for remote control

of the instrument, and for access from a computer using a web browser.

Risk of network failure

Before connecting the instrument to the network or configuring the network, consult

your network administrator. Errors may affect the entire network.

To establish a network connection, connect a commercial RJ-45 cable to the LAN port

of the instrument and to a PC or network switch.

Depending on the network capacities, the TCP/IP address information for the instru-

ment can be obtained in different ways.

●

If the network supports dynamic TCP/IP configuration using the Dynamic Host

Configuration Protocol (DHCP), and a DHCP server is available, all address infor-

mation can be assigned automatically.

●

Otherwise, the address must be set manually. Automatic Private IP Addressing

(APIPA) is not supported.

By default, the instrument is configured to use dynamic TCP/IP configuration and

obtain all address information automatically. This means that it is safe to establish a

physical connection to the LAN without any previous instrument configuration.

Risk of network errors

Connection errors can affect the entire network. If your network does not support

DHCP, or if you choose to disable dynamic TCP/IP configuration, you must assign valid

address information before connecting the instrument to the LAN. Contact your net-

work administrator to obtain a valid IP address.

needs to be installed for the remote command of R&S NGL/NGM via GPIB interface.

The GPIB interface, sometimes called the General Purpose Interface Bus (GPIB), is a

general purpose digital interface system that can be used to transfer data between two

or more devices. Some of its key features are:

●

Up to 15 instruments can be connected

●

The total cable length is restricted to a maximum of 15 m; the cable length between

two instruments should not exceed 2m

●

A wired "OR"-connection is used if several instruments are connected in parallel

To be able to control the instrument via the GPIB bus, the instrument and the controller

must be linked by a GPIB bus cable. A GPIB bus card, the card drivers and the pro-

gram libraries for the programming language must be provided in the controller. The

controller must address the instrument with the GPIB instrument address.

GPIB instrument address

To operate the instrument via remote control, it must be addressed using the GPIB

address. The default remote control address is factory-set at 20, the addresses of 0

through 30 are allowed.

The GPIB address is maintained after a reset of the instrument settings.

7.5.1 Channel Selection

The INSTrument:Select subsystem contains the commands for selecting the output

channels.

Each channel of the power supply is considered as separate "instrument", which is

required by the SCPI standard. Therefore, the SCPI commands use the INSTRument

node to select a channel.

You can only address the number of channels the instrument is equipped with, e.g. a

maximum of two channels for the NGL202, NGM202 or one channel for the NGL201,

NGM201.

You can address the channel by using the channel list command synax.

For more information, see

"Syntax for Channel List Commands" on page 183.

Example: Selecting a channel

You can select a channel either with an OUTput parameter, or just by the channel

number. This example lists all ways how you can select and query a selected channel.

7.9 Status Reporting Commands

The status reporting system stores all information on the present operating state of the

instrument, and on errors which have occurred. This information is stored in the status

registers and in the error queue. The STATus:OPERation and

STATus:QUEStionable subsystems contains commands to control the status report-

ing structure of the instrument.

See

Chapter A.3.1, "Structure of a SCPI Status Register", on page 186.

A Additional Basics on Remote Control

A.1 Messages and Command Structure

A.1.1 Messages

Instrument messages are employed in the same way for all interfaces, if not indicated

otherwise in the description.

●

Structure and syntax of the instrument messages:

Chapter A.1.2, "SCPI Command

Structure"

, on page 181

●

Detailed description of all messages:

Chapter 7, "Remote Control Commands",

on page 96

There are different types of instrument messages:

●

Commands

●

Instrument responses

Commands

Commands (program messages) are messages which the controller sends to the

instrument. They operate the instrument functions and request information. The com-

mands are subdivided according to two criteria:

Effects on the instrument:

●

Setting commands cause instrument settings such as a reset of the instrument or

setting the output voltage.

●

Queries return data for remote control, e.g. for identification of the instrument or

polling a parameter value. Queries are formed by appending a question mark to

the command header.

Applied standards:

●

The function and syntax of the common commands are precisely defined in stan-

dard IEEE 488.2. If implemented, they are used identically on all instruments. They

refer to functions such as management of the standardized status registers, reset

and self-test.

●

Instrument control commands refer to functions depending on the features of the

instrument such as voltage settings. Many of these commands have also been

standardized by the SCPI committee. These commands are marked as "SCPI

compliant" in the command reference chapters. Commands without this SCPI label

are device-specific, however, their syntax follows SCPI rules as permitted by the

standard.

Instrument responses

Instrument responses (response messages and service requests) are messages which

the instrument sends to the controller after a query. They can contain measurement

results, instrument settings and information on the instrument status.

GPIB Interface Messages

Interface messages are transmitted to the instrument on the data lines with the atten-

tion line (ATN) being active (LOW). They are used for communication between the con-

troller and the instrument and can only be sent by a PC which has the function of a

GPIB bus controller. GPIB interface messages can be further subdivided into:

●

Universal commands act on all instruments connected to the GPIB bus without

previous addressing; universal commands are encoded in the range 10 through 1F

hex. They affect all instruments connected to the bus and do not require address-

ing.

●

Addressed commands only act on instruments previously addressed as listeners;

addressed commands are encoded in the range 00 through 0F hex. They only

affect instruments addressed as listeners.

A.1.2 SCPI Command Structure

SCPI commands consist of a so-called header and, usually, one or more parameters.

The header and the parameters are separated by a whitespace. The headers can con-

sist of several mnemonics (keywords). Queries are formed by appending a question

mark directly to the header. The commands can be either device-specific or device-

independent (common commands). Common and device-specific commands differ in

their syntax.

Syntax for Common Commands

Common (= device-independent) commands consist of a header preceded by an aster-

isk (*) and possibly one or more parameters.

Table A-1: Examples of Common Commands

Command Command Name Description

*RST

Reset Resets the instrument.

*ESE

Event Status Enable Sets the bits of the event status

enable registers.

*ESR?

Event Status Query Queries the content of the event

status register.

*IDN?

Identification Query Queries the instrument identifica-

tion string.

●

MEASure:CURRent[:DC]?

●

MEASure:VOLTage[:DC]?

●

FUSE[:STATe] {0 | 1}

Long and short form

The mnemonics feature a long form and a short form. The short form is marked by

uppercase letters, the long form corresponds to the complete word. You can enter

either the short form or the long form; other abbreviations are not permitted.

Example:

MEASure:CURRent? is equivalent to MEAS:CURR?

Case-insensitivity

Uppercase and lowercase notation only serves to distinguish the two forms in the man-

ual, the instrument itself is case-insensitive.

Optional mnemonics

Some command systems permit inserting or omitting certain mnemonics in the header.

These mnemonics are marked by square brackets. The instrument must recognize the

long command to comply with the SCPI standard. Some commands are shortened by

these optional mnemonics.

Example:

FUSE[:STATe] { ON }

FUSE:STAT ON is equivalent to FUSE ON

●

Text

●

Character strings

●

Block data

The required parameters and the allowed value range are specified in the command

description.

Numeric values

You can enter numeric values in the following form. Values exceeding the resolution of

the instrument are rounded up or down.

Example:

VOLT 10V = VOLT 10

VOLT 100mV = VOLT 0.1

Special numeric values

The text listed below are interpreted as special numeric values. In the case of a query,

the numeric value is provided.

●

MIN / MAX

●

MINimum and MAXimum denote the minimum and maximum value.

Example:

You can query each setting command by adding a question mark. According to SCPI,

the responses to queries are partly subject to stricter rules than in the standard IEEE

488.2.

A.2 Command Sequence and Synchronization

A sequential command finishes the execution before the next command is starting. To

make sure that commands are actually carried out in a certain order, each command

must be sent in a separate command line.

As a rule, send commands and queries in different program messages.

To prevent an overlapping execution of commands the commands *OPC, *OPC? or

*WAI can be used. All three commands cause a certain action only to be carried out

after the hardware has been set. The controller can be forced to wait for the corre-

sponding action.

The R&S NGL/NGM series does not support parallel processing of remote commands.

If OPC? returns a "1", the device is able to process new commands.

A.3 Status Reporting System

The status reporting system stores all information on the current operating state of the

instrument and errors which have occurred. This information is stored in the status reg-

isters and in the error queue. You can query both via RS-232, USB, GPIB or LAN inter-

face (STATus... commands).

A.3.1 Structure of a SCPI Status Register

Each standard SCPI register consists of 2 or 3 parts (Event, Condition and Enable reg-

ister). Each part has a width of 16 bits and has different functions. The individual bits

are independent of each other, i.e. each hardware status is assigned a bit number

which is valid for all 2 or 3 parts. Bit 15 (the most significant bit) is set to zero for all

parts. Thus the controller can process contents of the register parts as positive inte-

gers.

STATus:QUEStionable:INSTrument:ISUMmary1 exists as often as device chan-

nels are available (e.g. NGL201 = 2 channels = 2 status register). Accordingly, the

description text of the channel information changes in

Figure A-1 (e.g. instrument 1 =

channel 1, instrument 2 = channel 2 etc.).

Status Reporting System

Additional Basics on Remote Control

R&S

NGL200/NGM200

187User Manual 1178.8736.02 ─ 09

Depending on the value of the read register, you can draw conclusions on the current

status of the device. For example, when the unit operates in constant voltage, the

result of the returned ISUM register is a decimal "2" which corresponds the binary

value of "0000000000000010".

Any part of a status register system can be read by query commands. A decimal value

is returned and represents the bit pattern of the requested register. Each SCPI register

is 16 bits wide and has various functions. The individual bits are independent, i.e. each

hardware status is assigned to a bit number.

Bits 9 to 12 are still "free" resp. unused (always return a "0"). Certain areas of the reg-

isters are not used. The SCPI standard defines only the "basic functions". Some devi-

ces offer an advanced functionality.

Each channel of the power supply is considered as separate "instrument" (SCPI stan-

dard definition). Therefore, e.g. the register

STATus:QUEStionable:INSTrument:ISUMary of the NGL202 or NGM202 is also

present two times (Isummary1 - Isummary2).

Description of the status register parts

The SCPI standard provides two different status registers:

CONDition

●

The CONDition register queries the actual state of the instrument. If you want to

query the constant voltage or current mode, you have to use the CONDition regis-

ter.

The CONDition register delivers a "1" (first bit set) in constant current mode (CC) and

a "2" (second bit set) in constant voltage mode (CV).

If the correct channel is selected and the red LED of the channel button lights up (CC

mode), the query of the CONDition register must deliver a "1".

Example:

STAT:QUES:ISUM1:COND?

EVENt

●

The EVENt status register is set (1) until it is queried. After reading (query), the

EVENt status register is set to zero.

The description of registers is only used for general explanation. Due to the complexity,

we recommend the general accessible SCPI standard document for more detailed

information.

For further description of the status register, see

Chapter 7.9, "Status Reporting Com-

mands"

, on page 175.

Event Status Register (ESR) and Event Status Enable Register (ESE)

The ESR is defined in IEEE 488.2. It can be compared with the EVENt part of an SCPI

ESE corresponds to the ENABle part of an SCPI register. If a bit is set in the ESE and

the associated bit in the ESR changes from 0 to 1, the ESB bit in the STB is set. The

ESE register can be set using the command *ESE and read using the command

*ESE?.

STATus:OPERation Register

In the CONDition part, this register contains information on which actions the instru-

ment is being executing or, in the EVENt part, information on which actions the instru-

ment has executed since the last reading. It can be read using the commands

STATus:OPERation:CONDition? or STATus:OPERation[:EVENt]?.

Bit No. Meaning

0 CALibrating

This bit is set as long as the instrument is performing a calibration.

1 to 3 Not used

4 MEASuring

This bit is set on event new measurement available.

5 to 9 Not used

10 Logging

This bit is set as long as "Logging" is enabled

11 Not used

12 FastLog

This bit is set once "FastLog" data is available

13 to

Not used

15 This bit is always 0

STATus:QUEStionable Register

This register contains information about different states which can occur. It can be read

using the commands STATus:QUEStionable:CONDition? and

STATus:QUEStionable[:EVENt]?. See

Figure A-1.

Table A-6: Bits of the STATus:QUEStionable register

Bit No. Meaning

0 Voltage

This bit is set while the instrument is in constant current mode (CC). The voltage is regula-

ted and the current is constant.

1 Current

This bit is set while the instrument is in constant voltage mode (CV). The current is variable

and the voltage is constant.

Query of an instrument status

Each part of any status register can be read using queries.

There are two types of commands:

●

The common commands *ESR?, *IDN?, *STB? query the higher-level registers.

●

The commands of the STATus system query the SCPI registers

(STATus:QUEStionable)

The returned value is always a decimal number that represents the bit pattern of the

queried register. This number is evaluated by the controller program.

Decimal representation of a bit pattern (binary weights)

The STB and ESR registers contain 8 bits, the status registers 16 bits. The contents of

a status register are specified and transferred as a single decimal number. To make

this possible, each bit is assigned a weighted value. The decimal number is calculated

as the sum of the weighted values of all bits in the register that are set to 1.

Error Queue

Each error state in the instrument leads to an entry in the error queue. The entries of

the error queue are detailed plain text error messages. You can look them up in the

error log or via remote control using SYSTem:ERRor[:NEXT]?. Each call of

SYSTem:ERRor[:NEXT]? provides one entry from the error queue. If no error mes-

sages are stored, the instrument responds with 0, "No error".
