Hi,
the BVA has a very small frequency calibration range.
I have solved this analogous problem on two 1000B by replacing the fixed
capacitor which determines the base frequency of the resonance inside the
oscillator.
I think it's the only way to solve the problem.
There are no

Dana,
As described in the following HP GPS splitter the isolation is > 40dB.
https://www.febo.com/time-freq/gps/hp58516a/HP_58516A.pdf
I use one of these 8-channel splitters.
I had a bad experience using a passive splitter of the minicircuits in the
10MHz distribution in my lab.

Hi Paul,
here the TICC noise floor.
Regarding the GPS/TICC versus a good Rubidium standard like the HP5065A ,
you cannot apreciate the Rubidium ADEV stability lower than 10Kseconds.

good job.
Have you made an analysis of the results and made some considerations about

Hi Bob,
I would like to know if there is a program to communicate with the F9T.
If I understand the acquisitions you have made with the TICC, they include
a direct input from the 1PPS of the F9T and a PPS by dividing the 5MHz of the
5065.
Is it correct?

Hi all,
I have not found details about the new product of the Jackson Labs, the Phase
Station.
The new driver is now added to the V1.32 Beta version of Timelab.
It seems to be an alternative of Timepod.
Can anyone anticipate something?

Hi,
This request interests me a lot because there is not a good technical product
on the market.
I would like something similar to the model 6460 TRAK Systems but with more
advanced features

I was wondering, and I do it to you too, if this Texas Instruments device

Gilles,
what manual you refer? (Part number)
Heating transistor are NPN.TO220 similar to TIP120
Driver is Q6 and NPN similar to 2N3904
U1 is LM2904N
U3 is uA208M

Hi Jan,
this is precisely the instrument that is lacking at a hobbyist price.
It would be excellent to have the possibility of measuring phase noise.
Can you anticipate the features of the Sampling DMTD?
Can it be used with Timelab?
We are waiting for your new ones.
Hi Mark,
the tests you did are between two different sources, so it is not a test
that can determine the noise floor of the instruments under test.
I understand that it is still a comparison on the field between the two
measuring instruments,
however I think it is interesting to
Hi Perrier,
The HP8405A is an analog vector analyzer that allows you to make phase
measurements like the oscilloscope with Lissajous shapes. This method is the
simplest one but allows quite approximate measurements and does not give you a
complete view of stability (Allan Deviation).
