AWR1642: Internal IF, waveform signal loopout

Adam Yao94020

Part Number: AWR1642

Hi champion,
   Is there any way to loop out below key signals from AWR devices from pin to test?

  1. The IF signal before ADC
  2. FMCW sawtooth waveform  generated from chirp generator but before up-frequency conversion to 77GHz

   Customer think they are important to do some test without the expensive 77GHz instruments.

Thanks,
Adam

    Hello Adam,
    The divided down version of the synth can be brought out on the OSC_CLK_OUT pin. Synth/32 or Synth/16 can be brought out.
    If you are using the Radar studio the "Regop" tab has a debug signal option. There you can select the signal to be brought out on the OSC_CLK_OUT pin.
    Regarding the IF out, we do have that option on analog domain. They can get the data in the digital domain post ADC and perform the analyses on that .

    Regards,
    Vivek
