Programming Overview 

The  SSG5000A  Signal  Generator  features  a  LAN,  USB  Device,  and  SIGLENT 

GPIB

—USB module interfaces. By using a computer with these interfaces, and a suitable 

programming  language  (Python,  C+,  .NET,  etc.,  and  NI-VISA  software),  users  can 

remotely  control  the  signal  generator  using  standard  SCPI  (Standard  Commands  for 

Programmable  Instruments)  commands.  The  SSG5000A  Programming  Guide  features 

more details on the specific commands.   

This chapter introduces how to build communication between the signal generator and a 

controller computer with these interfaces. 

 

4.1  Remote Operation 

The SSG provides both the USB and LAN connection which allows you to set up a remote 

operation  environment  with  a  controller  computer.  A  controller  computer  could  be  a 

personal computer (PC) or a minicomputer. Some intelligent instruments also function as 

controllers. 

 

 

Connecting via the USB Device port 

Refer to the following steps to finish the connection via USB-Device: 

1.  For standard installations, you can use NI-VISA on your PC for the VXI driver. If you 

wish to control the instrument without NI-VISA, use sockets or telnet. 

2.  Connect the SSG USB Device port to a PC with a USB A-B cable. 

3.  Switch on the SSG.
