Hi, I'll appreciate any help on the following. According to the link below [1], the PPS voltage for N200 should be in the range *[3.3, 5]* V p-p. [1] http://files.ettus.com/manual/page_usrp2.html#usrp2_hw_leds
I am getting a PPS signal through fan-outs from an external Firefly-1A GPSDO. I measured the output PPS voltage using a scope, and it is *2.52 V p-p* (terminated with 50 ohms). Would this relatively low PPS voltage work for N200? I am having a problem syncing two N200 units (2 LFRX/ 1 LFTX ), and I am not sure if this would be the cause? Thank you. Best wishes, Khalid
