Frequency command

[Douda]

Hello,

I need to measure some LEDs with a network analyser and get the precious measurements data with Labview Windows.

To get the Y data (signal's answer), I use the command "A?" and it works perfectly.

My problem is, when I want to get the X data (frequency), all the commands I tried didn't work.

I tried : "F?" -  "FREQ?" -  "DISP FREQ" .....

I can use some help here please !!

Thank you in advance

The first question is, are any of those the appropriate command string for your instrument? What analyzer are you using? Is there a previously built LabVIEW driver for this analyzer? Can you post the part of your code that produces the command strings. What version of labVIEW are you using?

Thank you very much for your answer ( which is quite fast BTW ) !

Problem solved 🙂

For others who may have a similar problem, how did you solve the problem? Thanks!

Focusing on the frequency commands ( found in the manuel) wasn't the right thing to do !

Since the frequency was on X axe, I just wrote the command " X? " ( without " " ) and it worked !

Hope I was clear enough
