Lock Detect Signal Output from FMCOMMS-4

Hello,

 

I am trying to use the AD9364 (on a AD-FMCOMMS4-EBZ with ZedBoard) as a sweeping signal generator where I am stepping the frequency from 2GHz to 3GHz with 20MHz steps. I am using the No-OS drivers (hdl_2016_r2 branch) and using the fastlock profiles (saving them in BBP and then loading them). I need to generate an output signal every time a new frequency is locked to trigger some external components. Is there any lock detect output signal that I can get the output from the FMCOMMS-4 board? Or can I drive a GPO pin every time the LO goes to a new frequency?

 

Thanks in advance.
