How to transfer data from a Keysight Spectrum analyser N9020B to my local control PC

Matteogala

Hello All,

I am fairly new to using, yet alone automating test equipment. Although I am trying to use the latter to automate a standard tests we do when releasing new software that produces RF frequencies.

I created a python script to connect to the spectrum analyser and I can set it up correctly for the tests I need to do through SCPI commands.

I also save the data as screenshots through the command " :MMEM:STOR:SCR <filename.png>"

I now want to transfer these screenshots to my local PC and I am struggling to understand which command to use. I have attempted to use the :MMEM:COPY:DEV  command although it fails.

This seems to be as I am only connected to the Spectrum analyser through port 5025 (SCPI port) and this does not allow file transfer? How would I then use the above command to achieve what I want?

Does anyone have more experience with this test equipment and could give me some hints where to look?

Thank you in advance for your responses!

(Spectrum Analyser I am using is a N9020B)

    Hi,

    I don't have that instrument. However, it's described on page 179 of the PDF user manual. Regardless of physical connection method (Ethernet, USB. etc) you can use a unified method called VISA. It eliminates messing about with TCP or UDP sockets, which is really not the way to work. For instance, if you're using Python then the library would be pyvisa. You could also use LabVIEW (either the graphical method, which is popular with automating tests, or using LabWindows/CVI if you're good at C programming. You could also consider MATLAB (it's a bit of an acquired taste), it has an Instrument Control Toolbox, and you can download the driver for your instrument from the Keysight website.

    It's highly recommended not to connect anything at the front end of that equipment unless you're really sure what you're doing (i.e. get someone experienced to set that up for you, or at least for them to specify what you should be connecting there) because it's easy to damage spectrum analyzer inputs, and that equipment is pricey.
