Hi Didier
Many thanks for that, nice to hear it arrived ok:-), and the changes sound
good.

Well I've scored a nice 5370B and now I'm thinking of a function generator
that is better than I have now. What's most important (apart from generating
the usual shapes) is a reference frequency input.
Whilst the HP 3325A/B (what's the difference?) looks good and would match
perfectly, I'd
The HP 33120A goes up to 15MHz, and can be uploaded with data to make
any arbitrary waveshape you can imagine. If it doesn't come with it,
a small customer-installable upgrade board can be added to lock to an
external reference. The 33220A is the current model, which runs up
to 20MHz. They
One problem with the HP3325 is the max frequency of the triangle and ramp waves
is rather low (10 KHz). Ebay item 290241023737 is a 3325A with a rubidium
timebase.
If you can do with sine and square waves, the FEI-5650A and 5680A rubidium
oscillators can be made into nice stable sources

Only Gets Slightly Warm.I Know Its A Subjective Thing But It Seems It Should
Feel Warmer.Maybe The Oven Controller Has A Problem.I'm Hoping
Hi,
The tube is in a vacuum so the ovens heat only has roundabout physical
paths to get to the outer case. If the tube feels warm at all at both
ends the oven and hotwire are probably working OK.
If you have a T type thermocouple temperature meter you can connect it to
the copper and silver

Also, check the Cs oven meter reading. If it's zero, the heater
controller/heater/thermocouple is suspect. Normally, when you turn the
unit on, the Cs oven will read up near the top of scale, gradually
declining as the oven warms up. Mine goes down to about 10 steady-state.
If it's doing this,
Does anybody have their Thunderbolt working directly with ntpd?
It's working now.
I haven't sorted out what I did wrong, but it was some type of operator error.
