I have a code for recording single waveform from two channels within 50 ns coincidence window in python. When I run the code, I can print instrument ID which tells my connection via USB interface is working but I am not able to record. I have an error related to timeout. Please see attached code and error below. The only thing I changed in the attached code is my instrument ID. I replaced exact address by XXXX. The error is as follows-
Instrument ID: TEKTRONIX,MSO64B,B028935,CF:91.1CT FV:2.0.3.950
Traceback (most recent call last):

pyvisa.errors.VisaIOError: VI_ERROR_TMO (-1073807339): Timeout expired before operation completed.
Please explain me the error and way to fix it. For more understanding, I have attached the snapshot of waveform saved by using another code. Why the waveform recording has error while saving image code is working well to save image? My ultimate goal is to record 100 acquisitions data within the coincidence window. But I am not able to record single acquisition.
Thank You
