[time-nuts] Self-contained divider board/design

[Bert, VE2ZAZ]

Mike,

This is neat. I do own a 5328A as well. It does not have option 040, but I believe it does not matter for the application you describe. Just tried it and it works as described. Never knew that!

Could anyone characterize the jitter performance of the Timebase Output at one Hz on a 5328A?

Bert

Just thought I'd mention this, since I haven't seen it here before.

The HP 5328a counter has a function where it can act as a (1:10-1:10e7) 
decade divider. It's in the documentation, but not obvious. One nice 
thing is that the input is subject to the level and slope controls, 
which are much more capable than what's found on a simple divider, so 
you can work with a wider range of input signals.

HP: "START A, STOP. Sets the counter to totalize the number of events 
at the A input until STOP is selected, for N=l on the RESOLUTION 
switch. For N>l, the number of counts divided by N is totalized. The 
scaled output (i.e., frequency of A/N) is available at the Time Base 
Out rear panel connector."

You can often find them for <$100 on eBay, shipping included.

Someone with better equipment than I could probably characterize the 
jitter, etc.
