Use LabView Instrument Driver Project for Keysight VNA - P9375A

[marcus_99]

Hello everyone. Currently, I am working on developing a program to measure S11 and S21 parameters using LabView control. The VNA we are using is the P9375A model from Keysight, and it comes with an Instrument Driver developed by Keysight itself.

The challenge I am facing is that there is only one example provided in the driver, and it is quite complex for me to comprehend given my current knowledge of LabView. The driver comprises more than 1000 SubVIs, each performing different tasks.

My task now is identifying the necessary SubVIs to conduct measurements of the S11 and S21 parameters, but it proves to be difficult among the multitude of SubVIs. Unfortunately, I couldn't find any documentation from Keysight explaining the instrument driver, unlike other manufacturers who provide such documentation.

If someone could assist me in understanding and navigating this task, I would greatly appreciate it.

Thank you for your time.

I have attached the LabView instrument driver project created by Keysight to control the VNA.

It seems you already worked with that driver library and saved some files with LV2023, while many others are still original LV2009 code.

Mind to share the original library or provide a link to the download (so we all can open the driver project)?

Most often all the functions in the driver are explained in the device manual: do you have the manual avaliable?

Hi GerdW, thanks for your response!

Here is the link to download the instrument drivers for network analyzers:

The only manual I have is the one provided by Keysight through their website: https://www.keysight.com/es/en/support/P9375A/streamline-usb-vector-network-analyzer-26-5-ghz.html#d...

I couldn't find any useful manual at the web...

Thank your for your time. I appreciate it.

I couldn't find a "useful" manual on that website. You better ask the Keysight support for their device and driver…

Ok GerdW. I have already opened a support case. I will update if I get the Instrument Driver manual.

Thank you for everything 👍

Hello everyone I contacted with Keysight support department and they have provided me with the manual. It was not as easy to find as they expected... xD

I attach the manual. I hope is useful to someone.

You can also find the file here, you have to click Resources, use the filter by type of content and then click in help files:
