Even with sawtooth correction the performance of the M12+T was found
inadequate for the LOFAR
Perhaps you could up-end the unit and reflect the display off of an adjustable
mirror (front surface, of course...).

Hi Bruce,
the PRS-10 datasheet is pretty smart in not showing the data below 10s
through, it would make their 10s performance not shine as much. There
certainly
could not be any measurement reason for not showing 10s ADEV.
As someone has mentioned, they also used a very bad GPS receiver
Hi Gang,
Does anyone have any documentation or manuals for the Austron 6014
Frequency Multiplier?
Thanks,

The other thing to consider is the noise in the built in FS725 PPS error
measuring system.
Whilst the resolution is 1ns it isn't that accurate and its instability
may also be worse than this.
Internal resolution may be as high as 200ps.

If one used a GPS timing receiver like the M12M + T or equivalent a
single shot PPS phase error measurement resolution of 1ns or better is
desirable.
This is easily achieved using a microprocessor with built in charge
redistribution ADC and a simple interpolation circuit.
One can either
A while back, there was a discussion on how best to use double balanced
diode ring mixers for delay measurements. I came upon a very useful paper
by Enrico Rubiola:
Tutorial on the double balanced mixer, Enrico Rubiola, 21 Aug 2006 , 52
pages, arXiv:physics/0608211v1 [physics.ins-det].
I have a 59992A J06 that needs a home. Before trying *Bay,
it seemed prudent to let the time-nuts list know, as it's of
limited interest there are not many available. If you're
using a 5370A or B, it's a handy accessory.

Here are some fresh, detailed plots of a TBolt for 8 days.

Perhaps this helps with recent VLBI questions.
Note the plots above are against a local standard and should
not be confused with plots people are making through TSIP or
TboltMon or LH, which are
