AFE58JD32LPEVM: Capturing multiple frames with TSW1400EVM

Marco Travagliati

Part Number: AFE58JD32LPEVM

Dear TI support team,

I'm setting up a system with the AFE58JD32LPEVM and TSW1400EVM. I would like to acquire M number of samples on N number of consecutive trigger events and download them on a single csv file. Is this possible using HSDC Pro? How do I need to set the trigger and the software to do so? Currently, I'm only able to acquire a number of sample M on a single trigger event.

Many thanks,

Marco

    Hi Marco,

    Thanks for reaching out. 

    We are trying to get this information from the TSW1400 team. I am sure you are in touch with Kalyan regarding the same. 

    We will get back to you once we receive the information to store the data for multiple capture events.

    Thanks & regards,
    Abhishek

    Hi Marco,

    I and Kalyan checked with the TSW team and here is their comment:

    "We do not have an option for the TSW1400EVM to capture and store all the samples for an N number of triggers in a single file. 

    If there is no constraint in the time interval between the triggers, we can possibly create a utility that would click the ‘Read DDR Memory’ button through automation in HSDC Pro and store the data in a file. This will be done for an N number of triggers, and finally we will have logic in the Utility to combine the files into one single CSV file.  Would this be useful for your application? If so, the utility, would be created in LabVIEW."

    If this is useful to you, please let me know, I can connect you to the concerned person.

    Thansk & regards,
    Abhishek

    Thank you Abhishek,

    Thank you Kalyan,

    It would be interesting for me to discuss this more. My trigger has a pulse repetition frequency that, depending on the specific case, is fixed and will be a value between 100 Hz and about 5 kHz depending on the case. Will the utility allow to catch all the N number of triggers for all these frequencies or for some of those without missing frames? Will it be possible to catch the time of each frame to verify eventually if some of the frame have been missed and apply eventually some correction in the data post-processing?

    Thanks,

    Marco
