Trigger out and In using ZC706 and FMCOMMS3

Category: Hardware
Product Number: ZC706 and FMCOMMS3
Software Version: Vivado 2015.4 and matlab R2021a


I am trying to build a transceiver including a signal generator and signal analyzer using ZC706 and FMCOMMS3. I wrote most of the codes in matlab for signal generation and signal analysis. 

What I want to do next, is that:

  • To generate a external trigger output which is an rising edge at the start time of the signal generation
  • To allow a trigger input to enable signal capture in signal analysis

The question is: 

  • For the trigger output, is there any signal that can indicate the transmission start in AD9361/FMCOMMS3?
  • For the trigger input, can I use the J57/58 in ZC706 routed to ENSM?

Thanks a lot,

  • You can configure the chip in FDD independent mode and pincontrol mode. As per the triggers to the two pins, the RX and TX paths will get enabled.

    In this mode, the ENABLE and TXNRX pins are internally remapped to Force Rx On and Force Tx On, respectively as below: Refer to the "FDD independent control" section in UG:
