Keysight N9020A (MXA) LabVIEW programming

[SamuelLIN]

Hi 

I was starting to automate the Keysight N9020A (MXA), and just looked at the Examples. 

Can anyone tell me what is the type of commands used to control the Spectrum Analyzer? Is it SCPI command? Thanks very much.

Hi Samuel,

Is it SCPI command?

Yes.

Can anyone tell me what is the type of commands used to control the Spectrum Analyzer?

Why don't you read the manual? It should contain all the information you need…

Hi GerdW

Thanks for your answer, it helped a lot. 

I asked the question when I looked at the manuals. I was confused about why the commands used in the example cannot be found in the manuals. However, you did be able to find commands that are similar to those used in the example vi, like:

That is why I asked the question. "Is it SCPI command?"

I tried the command listed in the manual and found it functioned well as the command used in the example vi. Are two types of SCPI commands......?

Hi Samuel,

with SCPI you can abbreviate commands. This should be explained in your manual, somewhere in the first chapter regarding SCPI commands…

In your image there is a list of several commands, using capitalized letters at the start of each command and  non-capitalized letters at the end. Only the capitalized letters are needed, the others can be omitted.

So instead of writing "FETCH:CHPOWER" you can also write "FETC:CHP" to yield the same effect…

You also don't need to use the same capitalization, SCPI doesn't care about that.

Yes, SCPI.

":CONF:<blah>;" is short for ":INSTrument:CONFigure:<blah>;".  There's a whole section in the manual on that command, which essential tells the instrument what type of measurement you are going to setup. See p42 - https://literature.cdn.keysight.com/litweb/pdf/N9062-90002.pdf?id=2915724

As GERDW said SCPI can be shortened and you must understand the context the commands are referring to.  As long as the command string is unique you can drop leading identifier so ":INST:CONF" can be just ":CONF".
