[time-nuts] Ublox ZED-F9T - group delay

[rf lab]

Hi All,

I have a ublox ZED-F9T with a very short RF trace to an SMA connector (<
1cm), so I expect the delay due to the RF line to be in the ~100's pico sec
range.  Using a GNSS simulator I measure the average 1pps delay relative to
the simulator to be about 25ns.  This figure is quite close to a typical
GNSS SAW group delay.

My question is if anyone has done something similar or knows what the
actual delay is for a ZED-F9T module.

Thanks
Fred
