Matlab for data acquisition from spectrum analyzers

[kelvchan]

Can matlab be used for data acquisition from spectrum anlaysers, network analysers with GPIB controllers? Any help on coding the GPIB controllers?

Re: Matlab question

You have to install the Data Acquisition Toolbox (for GPIB or DAQ control) and the Intrument Control Toolbox (for specific instrument control)...

check out the documentation of these toolboxes on mathworks.com

GBIP is verry easy to use with matlab! It works without any problems
I have used it with a spectrum analyzer.

Matlab question

You need that toolbox, but then it's easy.
For example, this sends/receives a few simple messages with one of my instruments.

g = gpib('ni',0,10);   % HP 33120A Function/Arb Generator
g.timeout = 1;
fopen(g);
fprintf(g,'*CLS');
fprintf(g,'*IDN?');
fscanf(g)
fprintf(g,'FUNC:SHAP SIN');
fprintf(g,'FREQ 3.57954525 MHz');
fclose(g);
