Hi ,
these jumps when tapping is normal when the HP5065A is restored to the life
ater a long storage time, they disappears after a long warmup (weeks).

Imagine having a source and fixed resistors with TC equal to zero.
The current variation of the coil varies between 2.5 and 6 mA.
In addition, the relationship between current and frequency variation of the
HP5065A is not linear.
If the pot is short-circuit, the current
Hi Corby,
I would first like to thank you for sharing your precious studies with us.
I love the HP5065A because it's an extremely interesting project and I'm
convinced like you we have a lot of room for improving its performance.

Hi Corby,
about the C field ten turn pot you write is a low TC pot. Normally a good
Vishay pot is 20 PPM/C, This is in conflict with the 1PPM resistors ad voltage
reference.
What kind of pot do you have used?

Hi Charles,
what you refer is the resistance relation referred to the LM299 source
around 14VDc but you have to consider
the tuning range of the pot, in the original HP5065A is 2E10-9.
Of course, it depends on the setting value of the variable resistance, but
you have to consider a

Hi all,
Thank you all for the precious answers and the links you sent me.
I'm studying them very carefully.
I still continue to look for the manual of the 5950 because I like to keep
the manuals of all the measuring instruments I have in my laboratory.
Thanks again

I have four EROS 5MHz oscillator brand new. The external connections are via

On the top there are coarse and fine tuning trim.
Does anyone have the pin connection and technical data?

Hi Attila,
I am doing the long therm stability test on a couple of HP5065, one original
A type, the second B or "super" compared with my best long therm stability, a
GPSDO HPz3816A.
This test will be 30 days long. It is a second test, with a second couple of
HP5065A/B, to verify the
stability and not the short term stability of the Super
version I agree it is improved..

Corby,
thanks for the information.
I'm definitely interested in the short therm ADEV but especially for Tau
from 1 day and over to test high stability standard over the time.
I will have further tests.
Cheers,

Very interesting news.
It would be nice to be able to set the RS232 port to work with the TICC in

Hi Corby,
I did several tests to verify the system noise floor using the same source
for both input channels. I have seen that the result varies a lot as the
difference in time between the two channels varies.
