Joe,
The single-shot resolution of the Option 040 series input is 10 ns.
The T.I. interval option adds jitter to make the averaging useful.
If your PPS was instead a burst or a clock, comparing it to your clock
would make more sense and you could use that higher resolution.
If I had a GPIB in
The trick is to link /dev/ttyS0 (or whatever) so that it occurs in
~/.wine/dosdevices/com1 which seemed to help a bit.

Hello Time-Nuts,
I have been playing with some Symmetricom SA.22c rubidium oscillators and
wanted to pass on some of the interesting information that I have found.
RDR Electronics has a large number of these units in stock.

I'm not sure what you mean by "the calculated difference to a pure

Sorry for the simple questions. Old hands can simply ignore this
message if it bothers you.
I have an HP 5328A that I have pieced together from broken units. As
soon as I make a ribbon cable for the GPIB card, I want to use it for
T.I. measurements. I know it isn't nearly as good as a 5370, but it

I would like to ask some advice about running TimeLab under Linux with Wine.
The program starts well (at least I guess), but no RS232 interface is found
in the acquire window. I tried the com port of my notebooks docking station,

Martyn,
In working with a 6T receiver we have noticed that sometimes the
reported offset correction is not correct. These instances appear to be
infrequent, and have only been noted as a single instance at a time. For
example you will occasionally get a -10.2nS correction when you should
get
, and how it generates 10MHz?

Both the outputs (REF and OUT, pins 9 and 15) are affected by the jump

Hello all,
I recently acquired a very nice PRS-45A for a very good price (<$500). I wired
up a -48V supply and within 30 minutes it was locked! I am very happy about
that. Now I am trying to communicate with it so I can read parameters such as
the hours on the tube, etc.
I do have the monitor
