GPIB readout from spectrum analyzer HP4195a

Does someone know how I can readout a HP 4195a spectrum analyzer with GPIB? I have a GPIB-USB cable. I can't readout the flopy disk from the spectrum analyzer in my PC.

Thanks, Ruben

Thanks Albert,

I've tried your programs, I can give the S.A. commands, like SAVE and GET, but I'm still not able to readout the data from the S.A. into labview. I hope you have some experience in that?

Call me on the phone, maybe a gpib card or installation problem.
one of the problems that can happen is a too speedy interface for an old instrument.

Thanks for your offer, but due to some help I used your programs to build a new one, when it is finished I'll attach it here.

Hi Albert

I just want to thank you for a very nice driver for 4195A.
Although I have not tested it yet and I need to update it for latest VISA, I consider your contribution as a "Day Saving" help.
Your post is the only one on the whole developper exchange, which has this driver.
Thank you for that.

Do not want you to consider submit your driver to NI (
Then it will be accessible to more people.

thanks again

Hi Olli


Just a comment.

I have been using this converted with this network analizer. It works.... but you need to be carefull. Sometimes, the GPIB from network analizer will lock without a reason and even powering down will not change a thing. The only way to get it out of the lock is to disconnect it from the network analyzer.


good luck
