Dear Ed,
You just hit the nail in the head. That is exactly the unit I am talking about.
But instead of showing Datum as the brand in the spec sheet you kindly sent to
me, it says Efratom. With all those mergers among T&F companies who knows!
I assume that the design is the same, unless someone
Dear John Ackermann,
I find your reply to my request to be very interesting. Without fear of asking.
May I know how do I achieve a Tau 0 measurement in a 1 second interval with my
setup? (HP-53132A + TimeLab).
Please tell me if I am wrong. I assume I would take the 10 MHz output from the

I don't know about the '202' part, but here's a data sheet for the PRFS:

The data sheet doesn't say which Rb oscillator is inside. Is it one of
the standard Datum models or a special one?

"MINI-TIC" for DMTD work
Hi Everyone!
Hi Bert,
What kind or sort of documentation is needed?
schematics?
PC layout?
software / firmware documentation?
I've been programming PICs intermittently for 10+ years. Some of my
projects use 2 or 4 line LCD displays. I have given other
microcontrollers a short test spin.
I've also done s
There is one calibration that can only be started by a GPIB command. I ran
into that, my unit constantly said something like "xxx calibration
required" or similar during power on. No way to do it with the front panel
buttons.
It is easy to start that cal using Visi, or via sending a GPIB com
Count me in, preferably for the 4 channel model.

Hi,
The Wavecrest DTS 207X has a number of proms and also battery back-up

Or are you sure that it is hardware? How old is your DTS?
