TSW14J56

Hello,

TIers!

When I use TSW14J56 with ADC, I want to trigger every external trigger (one pulse string of trigger signal here, trigger and collect signals from a fixed site at each rising edge of the pulse), ADC collects data of a fixed length and saves the data.Read all the previous data until I want to read the signal.How should this be done?

Best regards,

David

    David,

    Use HSDC Pro software automation (LabVIEW/MatLab/Python) to setup a hardware Triggered capture. This will arm the firmware to wait for a trigger, and upon trigger pulse from external source, it will complete the capture for user entered sample size and move the date to PC for user application consumption. This data can be retrieved from the temporary bin file maintained by HSDC Pro or by using the export as csv option in the HSDC Pro automation API.

     

    If the triggering will be happening continuously you will have to synchronize the trigger source with the HSDC Pro automation software loop to repeat the firmware re-arm & trigger process.

    If the expectation is to do a real-time streaming to PC, this cannot be done due to the USB throughput limitation & software latency involved.

     

    Regards,
