What is the bandwidth of the measurement?
Very low.
The measurements show here are made with an RC lowpass filter (5k/1µF)
on the output, but it doesn't change the statistical properties of
the noise at all.

Hi Ed,
I had a good look around for 45 minutes and I can't find where I saw it
expressly stated as a NVR command.
However, referring to the Z3801a manual, for instance, page 4-8 (page 74)
states that:

Hi,
I recieved a very odd communication, apparently from eBay, this morning.
It is a request to contact Congress about sales taxes on internet sales.
It APPEARS to be genuine, but I'm unconvinced.

Hi:
I opened up my Z3805A and after looking at the bottom of the main board think
it's already jumpered for RS-232.
See the bottom photo at: http://www.prc68.com/I/Z3805A.html#DB-25 near the
DB-25 connector.
There's only 3 zero Ohm jumpers and none of them are where the Z3801 jumpers
were.
I agree with Hal and if you have a reference you can tell how much the
crystal is off. My timing GPS receiver after 1 hour has a total uncorrected
wander of 112ns. Never seen 400ns on a timing receiver (maybe I haven't
waited long enough).

How good is your antenna? 112 ns is roughly 112 feet. That's not at all

You might watch the number of satellites and/or watch the position while it
does a survey.

Ummm, apologies for the errant posting
I'd bet you could determine a lot about the cause by looking at the spectra
of the error.I'm guessing that if the cause is an inaccurate survey
location then the wondering will be periodic because at one point in the
satilite's orbit it will be too close and then the distance will be to
far.
