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

    raise errors.VisaIOError(rv)
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

Can you explained me the detail process to be done in PC and in MSO 64B instrument in order to get communicated via VISA?
Thank You

Hi,
I have MSO64B with 4 GHz bandwidth. I also have key from Tek for 6GHz bandwidth. How do I upgrade the bandwidth of my oscilloscope?
Thank You

Hi Afonso,
I used the same link to download but could not get the supportive one. Also in the list shown in that link, there is not MSO64B. There is only MSO64. Do you have any instructive videos to be followed to download?
Thank You

Can you provide me link to download Tek VISA for MSO64B?

Hi Afonso,
I am trying to study timing resolution calculating the time difference between the waveforms within certain coincidence window ( 50 ns was just a number provided). So I would like to record an acquisition within a coincidence window. Can you explain me how do I do that?
Thank You

I have two channels from two detectors. I want to record continuous waveform (not single pulse as done by save as command in file menu) from these two channels setting a coincidence windows of 50 nano seconds. How do I do that?
