2 Welcome to R&S NGP800
The two or four-channel power supply series are based on a primary switched-mode
regulator with power factor correction. This concept allows the instrument to achieve
highest accuracy and lowest residual ripple.
The R&S NGP800 power supply series feature galvanically isolated, overload and
short-circuit proof outputs. The outputs can be connected in parallel and serial to ach-
ieve higher currents or voltages.
Multi-purpose protection functions, such as overcurrent protection (OCP), overvoltage
protection (OVP) and overpower protection (OPP) can be set separately for each chan-
nel. If the set limit is reached, the affected output channel is automatically turned off
and an indicator icon (
, , ) flashes on the display. The overcurrent protection can
also be linked to the other channels. If the current exceeds the limit on the affected
channel, all linked channels will be switched off.
The R&S NGP800 power supply series are also protected from overheating. Each
channel is equipped with a temperature sensor that monitors the channel operating
temperature for controlling the fan speed and overtemperature protection. If the safe
limit is exceeded, the output of the affected channel is switched off. The channel must
cool down to a defined threshold before the output can be switched on again. Opera-
tions of the other channels are not affected. Also, the actual operating speed of the
fans is monitored. If a fan is not running, e.g. rotor locked condition, all the outputs will
be switched off to prevent overheating.
The R&S QuickArb function allows freely definable voltage and current sequences with
a timeframe as short as 1 ms, e.g. to simulate different charging conditions of a battery.
The voltage and current points can also be grouped in different blocks which can be
sequenced and repeated independently to achieve a flexible arbitrary function genera-
tion.
With the R&S EasyRamp function, the R&S NGP800 power supply provides the oper-
ating condition to ramp up the supply voltage within a defined timeframe up to 10 s with
1 ms step size and it can be set independently for each channel. Furthermore, the
channels can be sequenced to ramp up the voltage output applied at different times.
With different slew rates and delays between channel outputs, it is easy to test multi-
voltage systems reliability. For the four-channel power supplies, the outputs can also
be arranged into two independent subgroups.
The analog input and digital I/O interfaces at the rear panel can be activated with an
option key. The analog input allows you to control the output directly using voltage sig-
nals (0 V to 5 V analog input corresponds to 0 to Vmax or Imax) and can be set inde-
pendently for each channel. The analog inputs are galvanically isolated from the chan-
nel outputs, making the connection simpler. The digital I/O provides an 8-bit control
port for various control functions. Each pin can be configured as input or output port, to
control any output channel, trigger an event, e.g. start arbitrary or to indicate various
conditions, e.g. over current protections.
The R&S NGP800 power supplies are equipped with a color 800 x 480 5 " TFT LCD
touch screen and a USB and LAN interfaces to control the instrument remotely. With
wireless LAN (WLAN) option, network connection can also be established wirelessly.

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 -20 °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

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 accepts worldwide mains voltage from 100 VAC to 240 VAC, 50 Hz / 60
Hz. No voltage selector switch is required. The instrument is protected by internal
fuses which is not user accessible. If the instrument is not powering on, this may indi-
cate an open fuse, the instrument must be sent for servicing. The instrument provides
rocker switch at rear panel, which disconnects the AC input. A standby switch at the
front panel toggles the instrument operation between normal mode and low consump-
tion power down mode.

5.5 Operation Modes
The R&S NGP800 operates in two different modes, i.e. CV and CC. The instrument
switches automatically between CV and CC depending on the connected load.
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.

● "Desired Hostname": The name assigned to the instrument used to identify it in
the network
● "DNS Hostname","mDNS Hostname" : The name assigned to the domain
name used to identify it in the network
When the connection is available, the network icon is highlighted in white on the device
status bar information.
6.15.1.1 LAN Connection
The R&S NGP800 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.
1. Connect the LAN cable to the LAN connector at the rear panel of the instrument.

Instrument option
R&S NGP-B105 (P/N: 5601.6000.02) option needs to be installed for the remote com-
mand of R&S NGP800 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 Configuration Commands
The following subsystems contain the commands for channel selection, voltage and
current settings for the instrument.
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.

7.7.1 Arbitrary
The ARBitrary subsystem contains the commands for configuring an arbitrary
sequence for the output channels.
Example: Configuring an arbitrary sequence
This programming example generates an arbitrary sequence for a selected channel.
The sequence starts at 1 V and 1 A for 1 sec, and both values are incremented each
second by 1. The generated arbitrary waveform is transferred to Ch1. When activated,
the R&S NGP800 provides the arbitrary waveform at the output of the selected chan-
nel, and repeats it 10 times.
// ************************************************
// Define and start the arbitrary sequence
// ************************************************
// selects channel 1
INST OUT1
// defines the sequence, i.e. starting at 1V, 1A for 1sec,
// and increments the voltage and current each second by 1
ARB:BLOC:DATA 1,1,1,0,2,2,1,0,3,3,1,0
// ARB:BLOC:DATA? queries the arb data
// sets the repetition rate
ARB:BLOC:REP 1
// queries the set number of repetitions
// ARB:BLOC:REP?
//sets the sequence repetition
ARB:SEQ:REP 10
// queries the set number of sequence repetitions
//ARB:SEQ:REP?
//sets the arbitrary endpoint behavior, when the QuickArb function is finished
ARB:SEQ:BEH:END HOLD
// queries the endpoint behaviour
//ARB:SEQ:BEH:END?
// transfers the arbitrary points to channel
ARB:SEQ:TRAN
//Enable the arbitrary sequence
ARB ON
//ARB? queries the arb status
// starts the sequence in channel 1
//turns on the output

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 176.

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 171
●
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.

Syntax for Device-Specific Commands
For demonstration purposes only, assume the existence of the following commands for
this section:
●
MEASure:CURRent[:DC]?
●
MEASure:VOLTage[:DC]?
●
FUSE[:STATe] {0 | 1}
●
FUSE[:STATe]?
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

| A vertical stroke in parameter definitions indicates alternative possibilities in the sense of "or". The
effect of the command differs, depending on the used parameter.
Example:
●
FUSE:LINK {1 | 2 | 3}
●
FUSE:LINK 1 sets the fuse link CH1 for the selected channel FUSE:LINK 2 sets the fuse
link of CH2 for the selected channel
[ ] Mnemonics in square brackets are optional and can be inserted into the header or be omitted.
Example:
●
FUSE[:STATe] { ON }
●
FUSE:STAT ON is equivalent to FUSE ON
{ } Parameters in curly brackets are optional and can be inserted once or several times, or be omitted.
Example:
●
VOLTage[:LEVel][:IMMediate][:AMPLitude] {<voltage> | MIN | MAX | UP |
DOWN }
The following are valid commands:
–
VOLT MAX
–
VOLT MIN VOLT 10
Syntax for Channel List Commands
For demonstration purposes only, assume the existence of the following commands for
this section:
●
VOLT? (@2)
●
OUTP (@2)
●
VOLT? (@1,3)
●
VOLT? (@1:4)
●
VOLT 5, (@1:4)
When adding a channel list parameter to a query, there must be a space character
between the query indicator (?) and the channel list parameter. Otherwise an error
-103, invalid separator occurs.
Table A-3: Special characters
@
The "@" sign in parameter definitions indicates in the sense of "at", this is part of the channel list
command syntax.
Example:
●
VOLT? (@2) queries the voltage at CH2
●
OUTP 1, (@3) turns on the output at CH3
, The comma sign in parameter definitions indicates in the sense of seperator for additional chan-
nels defination.
Example:
●
VOLT? (@1,3) queries the voltage at CH1 and CH3
●
VOLT? (@1,3,4) is equivalent to queries the voltage at CH1, CH3 and CH4
: The colon sign in parameter definitions indicates the defination of of channel range for additional
channel defination.
Example:
●
VOLTage? (@1:3) queries the voltage at CH1, CH2, CH3
●
VOLTage 5, (@1:3) configures CH1, CH2 and CH3 to 5 V

Overview of Syntax Elements
The following table provides an overview of the syntax elements:
Table A-4: Syntax Elements
: A colon separates the mnemonics of a command.
, A comma separates several parameters of a command.
? A question mark forms a query.
* An asterisk marks a common command.
" Quotation marks introduce a string and terminate it.
A whitespace (ASCII-Code 0 to 9, 11 to 32 decimal, e.g. blank) separates the header from the
parameters.
Responses to Queries
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.
●
The requested parameter is transmitted without a header.
VOLTage:PROTection:MODE?
Response: "measured"
●
Maximum values, minimum values and all other quantities that are requested via a
special text parameter are returned as numeric values.
VOLT:PROT? MAX
Response: 32.500
●
Boolean values are returned as 0 (for Off) and 1 (for On).
OUTPut:STATe?
Response: 1
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.

mands have been executed.

*OPC?
Stops command processing until
1 is returned. It occurs after the
Operation Complete bit has been
set in the ESR. This bit indicates
that the previous setting has been
completed.
Sending *OPC? directly after the
command whose processing
should be terminated before other
commands can be executed.
*WAI
Stops further command process-
ing until all commands have been
executed before *WAI.
Sending *WAI directly after the
command whose processing
should be terminated before other
commands are executed
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 NGP800 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. NGP802 / NGP822 = 2 channels = 2 status register). Accord-
ingly, the description text of the channel information changes in
Figure A-1 (e.g. instru-
ment 1 = channel 1, instrument 2 = channel 2 etc.).

177User Manual 5601.5610.02 ─ 04
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 NGP802 / NGP822 /
NGP804 / NGP824 / NGP814 is also present four times (Isummary1 - Isummary4).
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 165.

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
register. The event status register can be read out using the command *ESR?. The
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]?.

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.
Figure A-3: Decimal representation of a bit pattern
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
