Hi,

Any help with this is highly appreciated. I want to upload a QPSK signal onto Anritsu MG3700A signal generator via TCP/IP. I tried doing that using the information from the link below but got an error message from the signal generator when I want to download data to the sig gen.

The sig gen doesn't seem to like the following commands when I enter it Matlab:

% Turn off instrument before downloading waveform.
fprintf(signalGeneratorObject,':OUTPut:STATe OFF');
fprintf(signalGeneratorObject,':SOURce:RADio:ARB:STATe OFF');
fprintf(signalGeneratorObject,':OUTPut:MODulation:STATe OFF');
% Set the sample rate of the ARB clock to the sample rate of the baseband
% signal.
fprintf(signalGeneratorObject,[':SOURce:RADio:ARB:CLOCk:SRATe ' num2str(sampleRate)]);

Not sure what is going on. Perhaps the there is a difference command I need to enter.

在 MATLAB Online 中打开

You need to send line terminators.

fprintf(signalGeneratorObject, '%s\n', ':OUTPut:STATe OFF');
fprintf(signalGeneratorObject, '%s\n', ':SOURce:RADio:ARB:STATe OFF');
fprintf(signalGeneratorObject, '%s\n', ':OUTPut:MODulation:STATe OFF');
% Set the sample rate of the ARB clock to the sample rate of the baseband
% signal.
fprintf(signalGeneratorObject, '%s %d\n', ':SOURce:RADio:ARB:CLOCk:SRATe', sampleRate);

I receive the following error message on my sig gen: "Error Message ":OUTPUT:STATE" undefined command"

This happens when I enter "fprintf(signalGeneratorObject, '%s\n', ':OUTPut:STATe OFF');" on the Matlab commandline. Not sure why it doesn't like that command.
