PK,
The API would be the recommended way to automate with the VSG25. The VSG25 software and device does not support SCPI. SCPI automation is only supported on the VSG60 software.
The VSG25 API exposes most of the functionality of the user interface. It can be found in our SDK, linked below. See the user manual for programming examples.
