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 +3.505082408E-7
S +3.505082408E-7
S +3.505082408E-7
S +3.505082408E-7
S +3.505082408E-7
S +3.505082409E-7
S +3.505082408E-7
S +3.505082409E-7
S +3.505082408E-7
S +3.505082408E-7
S +3.505082408E-7
I converted it to following form:
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082408000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
0.0000003505082409000000
Then I tried to use ADEV by tvb (long life to Tom!). See attached file
1b.bmp
And I tried to create the charts for the collected data. See attached
file 1a.bmp.
But it seems I am doing something wrong. Any advises will be greatly
appreciated. Thanks !
