After more experimenting and measuring, I think the RF is done enough. I
found that the main 20 MHz and the 300 MHz LPFs were letting a lot of HF
above 1200 MHz straight through. I believe the choke I used in the 300
MHz LPF has a self-resonance in that range - it's a wire coil molded in
Hello,
Does anyone know if the Symmetricom 58534A integrated GPS timing antenna module
includes a holdover? Is it a GPSDO or just outputting 1pps from the LEA-M8F? I
know that has an ‘Autonomous 100 ppb hold-over’. Wondering if it makes sense to
feed to a TXCO.
Thanks,
Thom Lauret
There are some NOS FE-405A on ebay.
10MHz output.
They test very well!
Attached is a combined plot of five of the units.

Is the applied Vtune voltage clean?
tin order o do a "sanity" test I would just apply a 1.5v battery
