Hi Bert:
The PRS10 can use it's external 1 PPS input two ways.
1) as the input for a GPSDO, or
2) Time Tag (RS-232 command TT) of the input pulse

Have Fun,

Have you actually done it with the PRS10 and what was the result?

No problem for the PRS10 - there is an external pps input.
For the FRK-RbO I don't have a practical solution yet,
because I don't have a manual with circuit diagram found
for this 5 MHz model. This RbO is actually running free,
drift controlled by an external resistor set by two 10 turns
potentiometers. I think it should be possible to inject a
current instead. The control by eg. the Shera controller
need some modifs for this purpose which I have not yet done.
The time constant need to be modified too I think.

how are you controlling the Rb with the Tbolt? Bert

Bert,
I'm using at the moment a thunderbolt (with spare for testpurposes
using ext. other oscillators), a nice PRS10, a FRK-HLN-1A (5MHz with
external doubler to 10 MHz) and several HP10811.
I would like to build up with this a good and reliable reference
(PPS and Frequ.). My dream would be a good autonom. TIC with timestamp
possibility. At the moment the 53132A is doing a good job, but I miss
the time stamp possibility and single measurements at defined time
steps...

what do you use? Bert Kehren

I do, and I am also interested on other improvements!

Hi
I think it would be nice to have a show of hands as to how many are
locking
a Rb to GPS and what they use.

Uhm, isn't this exactly where you want to use the
still-smelling-like-brand-new-car PICTIC II with a good DAC
and a microcontroller ?
I guess the PICTIC II is not very good when stop pulses arrive
BEFORE
start
pulses which is a normal condition if a average time interval of
zero
between local pps and GPS pps is the aim.
So configure it to use a standard offset of one Xtal/Rb period ?
