TSW1400EVM: ADS5482_EVM with TSW1400_EVM + HSDC Pro GUI: maximum data size

Hans van Rossum

Part Number: TSW1400EVM

Longer data streams needed in application

{The default TSW1400 + HSDC Pro limits the maximum data size to 524288 samples}

Question:

For receiving longer data streams from data acquisition board TSW 1400

- Is it possible to program a data stream longer than 524288 samples (16 bits) using Python script?
--> to realize an analysis window of 1048576 - up to - 2097152 samples (16 bit).

Best regards,

Hans van Rossum

    Hi Hans van Rossum,

    Unfortunately the max capture depth is 524k samples and there is no way to adjust for larger data captures. To do this, you would need a fpga dev kit and would have to use an adapter ( https://www.ti.com/tool/FMC-ADC-ADAPTER ) to connect this device and write firmware for such device. The limitation will then be within the ILA capture buffer size which may or may not provide deeper capture. What is it you are trying to achieve? Can you use some delayed trigger signal perhaps?

    Hello Chase,

    Thanks for your prompt answer.

    For our experiments we planned to use the "external trigger input" J11. And the idea was to use a python script to process the received bin files. As we are only interested to detect signals in the noise and for that need preferrably longer datastreams.

    Our preference is to avoid possible development of new FPGA firmware.

    Would use of a delayed trigger signal enable us to receive longer data frames?

    Best regards, Hans

    Hi Hans,

    I was thinking if it is possible to use a main trigger to initiate your signal, and then use a delayed trigger to capture the ADC data after X amount of time. It won't increase the capture depth as that is capped at 512k unfortunately. There is no way to increase the capture beyond that unfortunately.

    Thanks, Chase
