Using SCPI

To access the SCPI interface, you use software such as VEE or NI Labview. Additionally, you can use the VISA COM library from a programming language such as C++, C#, or VB.

The SCPI interface provides a subset of commands that are exposed in the .NET API. To access some of the 89600 VSA's advanced features, such as multi-measurements, user corrections, fixed equalization, and user math, you must use the .NET API.

An example C# program is provided that shows how to use the VISA COM library. There is also some example VEE programs.

Keysight Interactive IO tool

Another way to issue SCPI commands and queries is to use the Keysight Interactive IO application that is included with the Keysight IO Libraries.

To start Interactive IO, click the Start > (All) Programs > Keysight IO Libraries Suite > Utilities > Interactive IO.

Then select Connect > Connect... from the main menu and enter the resource name corresponding to the channel and port defined by the VSA SCPI Configuration tool, as shown below:

Once you have connected to the 89600 VSA SCPI interface, you can send commands and read the responses using the Interactive IO tool.
