Re: ProgRock/ProgRock2 vs GPSDO (trimble)

 

Over the last few weeks I have been 'watching' a gps conditioned progrock on
42Mhz with a statistical frequency counter whose timebase is locked to GPS via
a second GPS receiver. The progrock deviation from 42000000.0Hz is averaged at
0.7Hz with occasional far larger deviations caused, I believe, by power supply
and progrock gps's 1pps issues. Not awesome performance, but adequate for most
'sensible' people but not for 'Time-Nuts'.

Hi Hans,

any plan to compare ProgRock/ProgRock2 used as GPSDO vs Trimble and/or
others GPSDO for providing 10MHz reference signal? Still I am not sure
it can stay within well less than 1Hz if set for 10MHz. Having just one
GPSDO, even assuming is reliable, I could not simply test it.

Could set up this test for us?

I could volunteer lending you mine, you would need at least three...
