Might want to dial that back a bit.
Since 12V/7ah batteries are mentioned I am assuming standard small
gelcell units.
Proper fl
use nickel-iron battery [Edison Accumulator] which is not sensitive to
deep discharge, over charge and last for min twenty years -
unfortunately it does not fit into the American business model --because
it last to long--so it is not produced in the US any more.

I think they're reporting the phase offset of the 10MHz to the PPS, but as you
say, I haven't measured it yet.

Regarding my comment earlier that my GPSDO and this Z3812A don't agree on
phase. I see just now a fairly quick phase movement of the phase between the
two, and I see that there is a line on the Satstat program that may explain
this: 1PPS TI +50.0 ns relative to GPS. Just a few minutes ago, it

Hi
One of the interesting things about these little receiver modules is that they
don’t all report the same survey location. There are NIST papers with examples.
You could probably spend a lot of time on the “why”.
If you are getting “poor geometry” errors, either you have an antenna issue, or

If REF-0 is the only one that can output the data that would certainly put
me in a shot myself in the foot position wouldn't it?:-)
However, we do know from Arthur that REF-1 will operate stand alone, so

Sorry if these comments are a bit naive, but this is my first exposure to a
Z38xx.
I've got mine powered on and connected to the antenna. After referring to
Stewart's original post (once again) I've managed to download HP's SATSTAT and
get it running. When I connected to the REF-1 unit (with
