1. To Set the Output Load
For the [Output] connector on the front panel, the generator has a built-in
50Ω series impendence. If the actual load does not match the set one,
the displayed amplitude and offset will be incorrect. This function is used
to match the displayed voltage with the expected one.
Steps for setting the load:
Press Utility →Output Setup→ Load, to enter the following interface.
Please note that the load parameter shown on the right
bottom is the default setting when the power is on or the pre-set load
value. If the current value is valid for the output, then current value will be

voltage will not equal the real voltage.
2. To Set the Invert Waveform
Press Utility →Output Setup→ Invert, to set the Inverse Waveform Output.
When the waveform is inverse, no offset will change.
3. To Set the Sync Output
The generator provides Sync output through the [Sync] connector on the rear
panel. All standard output functions (except DC and Noise) have a
corresponding Sync signal. For some applications, they can be disabled if
users do not want to use it,
In the default setting, the Sync signal should be connected to the
[Sync] connector (activated). When the Sync Signal is disabled, the
output voltage of the [Sync] connector is level low.
In the Inverse Mode, the Waveform that corresponds to the Sync
Signal does not inverse.
The Sync Signal is a Pulse Signal with fixed positive pulse width,
which is more than 50ns.
For non-modulated waveform, the Sync Signal reference is the
carrier.
For internal modulating AM, FM and PM, the Sync signal reference
is the modulated signal (not the carrier signal).
For ASK and FSK, the Sync Signal Reference is the keying
Frequency.
For a Sweep, when the sweep starts, the Sync Signal becomes TTL
Level High. The Sync frequency equals the specific Sweep time.
SDG800 User Manual 68
For the Burst, when the burst starts, the Sync Signal is Level High.
For the External Gated Burst, the Sync Signal follows the External
Gated Signal.

3 Commands and Queries
3.1 IEEE 488.2 Common Command Introduction
IEEE standard defines the common commands used for
querying the basic information of the instrument or executing
basic operations. These commands usually start with "*" and
the length of the keywords of the command is usually 3
characters.
3.1.1 IDN
DESCRIPTION
The *IDN? query causes the instrument to identify itself. The
response comprises manufacturer, model, serial number,
software version and firmware version.
QUERY SYNTAX

has no other effect on the operation of the device because the
instrument starts parsing a command or query only after it has
completely processed the previous command or query.
The *OPC? query always responds with the ASCII character 1
because the device only responds to the query when the
previous command has been entirely executed.

The *SRE command sets the Service Request Enable register
(SRE). This command allows the user to specify which summary
message bit(s) in the STB register will generate a service
request.
A summary message bit is enabled by writing a ‘1’ into the
corresponding bit location. Conversely, writing a ‘0’ into a given
bit location prevents the associated event from generating a
service request (SRQ). Clearing the SRE register disables SRQ
interrupts.
The *SRE? query returns a value that, when converted to a
binary number represents the bit settings of the SRE register.
Note that bit 6 (MSS) cannot be set and it’s returned value is
always zero.
COMMAND SYNTAX
*SRE <value>
<value> : = 0 to 255
QUERY SYNTAX
*SRE?
RESPONSE FORMAT
*SRE <value>
EXAMPLE
The following instruction allows a SRQ to be generated as soon
as the MAV summary bit (bit 4, i.e. decimal 16) or the INB
summary bit (bit 0, i.e. decimal 1) in the STB register, or both are
set. Summing these two values yields the SRE mask 16+1 = 17.

3.1.8 STB
DESCRIPTION
The *STB? query reads the contents of the 488.2 defined status
register (STB), and the Master Summary Status (MSS).
The response represents the values of bits 0 to 5 and 7 of the
Status Byte register and the MSS summary message.
The response to a *STB? query is identical to the response of a
serial poll except that the MSS summary message appears in bit
6 in place of the RQS message.

3.1.9 TST
DESCRIPTION
The *TST? query performs an internal self-test and the response
indicates whether the self-test has detected any errors. The
self-test includes testing the hardware of all channels.
Hardware failures are identified by a unique binary code in the
returned <status> number. A “0” response indicates that no
failures occurred.

4 Programming Examples
This chapter gives some examples for the programmer. In these examples you can see
how to use the NI-VISA lib and the commands which have been described before this
chapter to control our devices. By the examples’ guide, you can develop more functions
application as you want. This example is developed by Visual Studio project.
Main topics of this part:
Example of Vc++
Example of VB
Example of MATLAB
Example of LabVIEW
4.1 Example of VC++
Environment: Win7 32bit system, Visual Studio
The functions of this example: use the NI-VISA, to control the device with USBTMC or
TCP/IP access to do a write and read.
Follow the steps to finish the example:
1、 Open Visual Studio, create a new VC++ win32 console project.
2、 Set the project environment to use the NI-VISA lib, there are two ways to use
NI-VISA, static or automatic:
2.1 Static: find files: visa.h, visatype.h, visa32.lib in NI-VISA install path. Copy
them to your project, and add them into project. In the projectname.cpp file, add
the follow two lines:
#include "visa.h"
#pragma comment(lib,"visa32.lib")
2.2 Automatic:
Set the .h file include directory, the NI-VISA install path, in our computer we set
the path is : C:\Program Files\IVI Foundation \VISA\WinNT\include. Set this path
to project---properties---c/c++---General---Additional Include Directories: See the
picture.
Programming Guide
50
Set lib path set lib file:
Set lib path: the NI-VISA install path, in our computer we set the path is :
C:\Program Files\IVI Foundation\VISA\WinNT
\lib\msc. Set this path to project---properties---Linker---General---Additional
Library Directories: as seen in the pictures below.
Set lib file:project---properties---Linker---Command Line---Additional Options:
visa32.lib
Include visa.h file: In the projectname.cpp file:
#include <visa.h>

4.4 Example of LabVIEW
Environment: Win7 32bit system, LabVIEW 2011
The functions of this example: use the NI-VISA, to control the device with USBTMC
and TCP/IP access to do a write and read.
Follow the steps to complete the example:
1、 Open LabVIEW, create a VI file.
2、 Add controls. Right-click in the Front Panel interface, select and add VISA
resource name, error in, error out and some indicators from the Controls column.
3、 Open the Block Diagram interface. Right-click on the VISA resource name and
you can select and add the following functions from VISA Palette from the pop-up
menu: VISA Write, VISA Read, VISA Open and VISA Close.
4、 Connect them as shown in the figure below
5、 Select the device resource from the VISA Resource Name list box and run the
program.
Programming Guide
65
In this example, the VI opens a VISA session to a USBTMC device, writes a
command to the device, and reads back the response. In this example, the specific
command being sent is the device ID query. Check with your device manufacturer for
the device command set. After all communication is complete, the VI closes the VISA
session.
6、Communicating with the device via TCP/IP is similar to USBTMC. But you need to
change VISA Write and VISA Read Function to Synchronous I/O. The LabVIEW
default is asynchronous I/O. Right-click the node and select Synchronous I/O
Mod>>Synchronous from the shortcut menu to write or read data synchronously.
7、 Connect them as shown in the figure below
8、 Input the IP address and run the program.
