Magnus and Bob.
I appreciate the comments and the suggestions are easily implemented.
Technical term "Piece-O-cake".
One other note the the Z3801 uses a more negative voltage to raise
frequency while the Piezo and FRS use a positive voltage.
Absolutely agree on the offset. Been trying to do that.
Hi,
Well, that was the data I was able to find (and I referred to TvBs page
where I found it). If you have more accurate data, please share so we
can get the numbers right.
The Z3801A will do a least square estimate of frequency error and then
translate that into an initial DAC setting assumi
Hi
Ummm ….. er ….
The 10811 that is used in the Z3801 has a *larger* electrical tuning range than
the standard
10811 not a smaller one. It’s tuning range and the TBolt OCXO’s tuning range are
very similar.

Paul,
We just want to help you with that curiosity, it sounds like a fun
little project. :)
The FRS-C [1] has a range of +/- 1E-9 over 0-5V, so EFC sensitivity is
4E-10/V.
The Z3801A has a range of 5.20E-10 [2] over -5V to +5V [3], so EFC
sensitivity is 5.2E-11/V.
So, it looks like you n

Magnus and Bob,
Thank you for your response. As far as the original HO 10811 oscillator
goes there is some well written details on it behavior and sensitivity. It
was not the same as a standard 10811. A far smaller range as I recall. But
the data is there.
Its funny on the RB I have the EFC range f
Is everybody setup to watch it and collect lots of data?
Anybody have a list of tools/toys for collecting data?

Hi
Simple answer - no, you cannot convert one to the other.

The one big difference I know of (there must be others) is that the 131A
"only" has a time resolution of 500ps, whereas on the 132A it is 150ps.

How similar are the 131A and the 132A ? Is it possible to upgrade a 131
into 132 ?

Interesting question!
I suspect not, not in any straightforward fashion anyway, but I'm sure
others would know better than me.
