  • Page 7: Programming Overview

    Programming Overview The SSG6080A supports both USB and LAN interfaces. By using these interfaces, in combination with NI-VISA and programming languages, users can remotely control the signal generator. The instrument comes with an embedded web interface; VXI-11, Sockets and Telnet protocols can be used to communicate with the signal generator.
  • Page 8 Click Unzip, the installation process will automatically launch after unzipping files. If your computer needs to install .NET Framework 4.6.2, its setup process will auto start. The NI-VISA installing dialog is shown above. Click Next to start the installation process. SSG6000A Programming Guide...
  • Page 9 Set the install path, default path is “C:\Program Files\National Instruments\”, you can change it. Click Next, dialog shown as above. Click Next twice, in the License Agreement dialog, select the “I accept the above 2 License Agreement(s).”, and click Next, “Start Installation” dialog shown. Click Next to run installation.
  • Page 10 Now the installation is complete, reboot your PC. Connect the Instrument Depending on your specific model, your signal generator may be able to communicate with a PC through the USB or LAN interface. This manual uses the USB connection in the examples. (For instructions to communicate with a PC through the LAN interface see the User Manual.) Connect the USB Device interface at the rear panel of the signal generator and the USB Host interface of the PC using a USB cable.

  • Page 11: Build Communication Using Sockets

    Refer to the following steps to finish the connection via USB: 1. Install NI-VISA on your PC for GPIB driver. 2. Connect the signal generator USB Host port to a PC’s GPIB card port, with SIGLENT USB- GPIB adaptor. 3. Switch on the signal generator.

  • Page 12: Remote Control Capabilities

    1.2 Remote Control Capabilities User-defined Programming Users can use SCPI commands to program and control the signal generator. For details, refer to the introductions in “Programming Examples”. Send SCPI Commands via NI-MAX Users can control the signal generator remotely by sending SCPI commands via NI-MAX software. 1.2.2.1 Using USB Run NI MAX software.
  • Page 13 NOTE: The “*IDN?” command (known as the Identification Query) returns the instrument manufacturer, instrument model, serial number, and other identification information. 1.2.2.2 Using LAN Add a Network Device, and select a VISA TCP/IP Resource as shown: Run NI MAX software. Click “Device and interface”...
  • Page 14 NOTE: Leave the LAN Device Name BLANK or the connection will fail. After a brief scan, the connection should be shown under Network Devices: SSG6000A Programming Guide...
  • Page 15 Right-click on the product and select Open NI-VISA Test Panel: Click “Input/Output” option button and click “Query” option button. If everything is OK, you will see the Read operation information returned as shown below. SSG6000A Programming Guide...

  • Page 17: Scpi Overview

    SCPI Overview 2.1 Command Format SCPI commands present a hierarchical tree structure containing multiple subsystems; each of the subsystems is made up of a root keyword and several sub keywords. The command string usually starts with a colon “:”, the keywords are separated by a colon “:” and the parameter settings are separated by spaces.

  • Page 18: Parameter Type

    The content in the square brackets can be ignored. When the parameter is ignored, the instrument will set the parameter to its default. For example, In the “[:SOURce]:POWer?” command, sending either of the commands below can generate the same effect: :SOURce:POWer? :POWer? Vertical Bar |...
  • Page 19 For example: [:SOURce]:AM:STATe OFF|ON|0|1 Enumeration The parameter could be any of the values listed. For example: [:SOURce]:SWEep:STATe OFF|FREQuency|LEVel|LEV_FREQ Valid parameters are “OFF”, “FREQuency”, “LEVel” or LEV_FREQ. Integer Except other notes, the parameter can be any integer within the effective value range. For example: [:SOURce]:SWEep:STEP:POINts <value>...

  • Page 20: Command Abbreviation

    The parameter <value> can be set to any real number between -100 and 100. String The parameter should be the combinations of ASCII characters. For example: :SYSTem:COMMunicate:LAN:IPADdress <“xxx.xxx.xxx.xxx”> The IP address can be set as the string “192.168.1.12”. 2.4 Command Abbreviation All of the commands are not case sensitive, so you can use any of them.
