Agilent E4980A control

[ma994]

Hi everyone, is it possible to control the Agilent LCR meter E4980A using a phone cable usb-usb c with my computer instead of GPIB cable.

As per the images on the website and the manual, it does support USB control (mini USB) provided on the back and the front panel USB is only for USB drive captures.

NI VISA Drivers support GPIB/USB/LXI and hence you can easily use all the supported communication protocol without changing code.

You might need to get the right cable if your laptop has only USB-C. If it is a typical USB-A port on computer and laptop then you would need a USB-A to Mini-B cable.

Thank you very much for your response. I have another question please..I found a program in this community and when opening it, I always have these warnings in the image below. What could be this error? I even change the path of the project in the same folder of the drivers but it's not working.

It looks like the user who developed the code had the Agilent Driver in a folder under desktop during development instead of having inside instr.lib and hence the VIs are looking at that location. Whereas you have them installed in instr.lib (correct location) and giving a piece of information that those VIs were found in the new location and linked.

This will go away once you save the VIs or mass compile them on your PC.

Don't forget to mark the solution if your question was answered.

Thanks, stay safe!
