I'm trying to read the currently set value from an Agilent E5071C network analyser (ENA), using a TCPI/IP connection method.
As one example of a SCPI command I've tried for setting the start frequency:
The below command works for setting the start frequency:
The below command should return the currently set frequency:
I've used the Matlab code below to set the start frequency to 1GHz, which works:
fprintf(agilentENA, [':SENS:FREQ:STAR 1e9'])
But when I try to query it with the below code, I just receive an error:
out = str2double(fgets(agilentENA));
The error I receive is:
Warning: Unsuccessful read: A timeout occurred before the Terminator was reached.
I've tried increasing the timeout to 100 too, but it still shows the same error message. It's odd how I can write to the instrument, but cannot read to it.
Thanks in advance for any support.
Best Regards, Charlie
