Re: post modifications
If you like GRC code generation, you will love Python snippets, which
allow for code insertion in the generated GRC file for exactly these
kinds of things.

Hi Marcus,
I tried to improve the situation. I had another look at [0,1].
From [1] (N310 manual)
"[..] which can both be used as time- and clock references. The GPSDO
will function as a reference even when there is no GPS reception."
This helps. I set
Sync: "Unknown PPS"
Clock/Time source: "O

Nope, that doesn't set a time register. You don't actually need a pulse
per second – you need
Hi Marcus,
thanks for your prompt answer.
I don't have a PPS signal readily available. Would a 10MHz reference
suffice as well?
Do I get rid of this issue if I use a GPSDO? We have the hardware
(antennas + modules) available but no GPS signal in our lab.
Besides, I was really hoping that o
