Hi
Either the output data is with the counter set to time mode (and it’s in 100’s
of ns) or you have it
set to frequency mode and have a very stable system.

The counter is in TIME MODE. And simple calculation could transform it
to frequency as necessary. For example:
1/(350.50824*10^-9)
2852999.97512184021693755330
OR
1/0.00350508240900
2852999.96779619226350692058
Which is pretty close to my DDS VFO freq. value [2853000]

Hello,
I would like to create some charts for ADEV for following setup:
HP5386A counter connected to External REF. (OCXO). The input of counter
connected to my DDS VFO. The frequency on VFO is 2853000 Hz.
Here is what I got from counter via GPIB:
S +3.505082408E-7
S +3.505082408E-7
S +3.50
