The HP 5370B is spec'ed for a single-shot time interval resolution of 20
picoseconds, not 10 nanoseconds. The Racal 1992 is only spec'ed at 1
nanosecond.
If you're thinking of buying a Racal 1991 or 1992, watch out for bad
switches. One type of switch that was used is failing due to age. If
Current-generation CSACs work like rubidium standards, and perform similarly.
The optical excitation comes from a laser diode rather than a conventional Rb
vapor lamp. They can't be considered primary standards.
Compare the ADEV graphs of some of the 'classical' Cs standards with what you

List,
I’m still confused about the new Symmetricon CS unit. Is it truly a cesium
primary standard or is it a secondary standard that happens to use cesium?
IF it is truly a primary standard, is saving up the $1500 for one a better deal
IN THE LONG RUN than getting a used HP or other brand C.S
List,
Being fatally infected with the Time-Nuts disease I’m inclined to spend ever
more amounts of money in pursuit of greater minutia. Thus the question of the
Racal-Dana 1992.
I have at present two HP 5370B units which are spec’d to 10 nS resolution IIRC.
I believe it was posted on this li
List,
About a bazillion posts ago on the list (this translates to about two months)
there was a discussion about cooling of very hot instruments such as the HP
5370A/B series.
One poster related how he had replaced the stock OEM fans on a HP 5370 with
ones used for cooling computers and achi
A while ago I was asking if anyone had a dist amp for 10mhz and many
suggested looking for video distribution amps. (and a few offered up
real 50ohm 10mhz dist amps, and I thank you!)
To make a long story short, I found a set of 3 VideoTek VDA-16's in a
1U rack mount on ebay for the completely rea

Thanks Jim,
