I am currently working on a remote control for a HB8510B. Although the design is pretty old, there is a lot of information available and i was therefore able to implement the necessary functionalities quickly.
However, I got stuck trying to restore local control via GPIB for example after a syntax error.
In the programming manual, it says to use the GTL or DCL/SDC command. Unfortunately, the VNA always displays a syntax error on the second character regardless of the transmitted command (GPIB Universal Commands and GPIB Addressed Commands). Programming codes work just fine. I am obviously missing something big here….
Any help is much appreciated!
