Question about the Dump function

    Question

  • Hello all,

    I make a dump operation and get a dump file. But I want to ask what stage the dump data is located in the RX procedure.

    For example, I leaned the RX procedure as follows:

    A. RF analog signal captured by RF2450 board, and demodulate by MAX2829 to be  the Baseband analog signal.

    B. Baseband analog signals into ADC(AD9862) to be the baseband digital signals(be already quantized).

    C. Baseband quantized digital signal is sent to RCB.

    D.  PC software algorithm.

    Do I understand corretly? And when I dump to get the signal block,  which step is the program located in?

    Thanks a lot.

  • One step should be added between C and D. That is, RCB sends digital baseband signal into PC memory via DMA. So the dump function is simply writing the data from memory into a file.
