Query IQ Data from Signal Generator

Hi,

I would like to pull IQ Data from the Signal Generator (Agilent Technologies, N5182A (Option 654), MY50140960, A.01.85).

According to the manual (as below), I can query using :MEMory:DATA:IQ? "<file_name>" syntax.

Have written the below code to pull the IQ of waveform_file already in the Signal Generator.

IP_SG = '10.10.100.131'
rm = visa.ResourceManager('@py')
inst = rm.open_resource('TCPIP::'+ IP_SG + '::INSTR')
inst.timeout = 30000
print("Session ID : %s" % (inst.session))
print("Instrument identification information : %s" % (inst.query("*IDN?").rstrip()))
data = inst.query_binary_values(:MEMory:DATA:IQ? "waveform_file")

Unfortunately getting timeout error, eventhough the timeout is 30s currently.

As the output is not entirely float, I dont think it require for a datatype or is_big_endian to be specificied in the inst.query_binary_values(). I even tried inst.query() which results in the same timeout error.

Do you happen to face the same problem before?

If everything works as expected with the other command I would say yes, since the issue appear to be specific to your instrument and command and not directly related to PyVISA or PyVISA-py.

To instal you can first do pip uninstall pyvisa-py and then pip install https://github.com/MatthieuDartiailh/pyvisa-py/tarball/fixes.
