ADS5263EVM: ADS5263EVM + TSW1400 Synchronous Sampling and Complex FFT Save to File

Part Number: ADS5263EVM
Other Parts Discussed in Thread: ADS5263

Hi,

Using the ADS5263EVM + TSW1400, can I do the following:

  1. Capture a data sequence (ideally 64k in length) from each of the four ADC's inside the ADS5263 on the ADS5263EVM card (such that they are synchronous to the same starting sample clock cycle) for subsequent FFT processing by the TSW1400 card followed by,
  2. Saving all four synchronous FFT's in complex format (real+imag or mag+angle) to CSV text files (or equivalent) for off-line processing?

Thanks in advance,

Nath

    Nath, we can support No.1. No.2 formtat is below. So we don't have the complex FFT resutls. while when you get No.1 data, you can run fft in Matlab for complex data.

    Thanks!

    Hi Xiaochen,

    Thanks for your response.

    I have downloaded HSDC Pro v5.00 to have a look through the menus and I've found 'Save Integer (I32) Codes as CSV File' under 'File'.

    Does this allow me to save all four time-aligned ADC sample slices in one CSV file as decimal values that I can pull directly into Excel?
