A list member did some experimenting with the unit and came up with this very useful information:
"press and hold RST button, then MODE toggles LPF (low pass filter), GATE toggles input
impedance"
I wonder what the LPF cutoff freq is?
I am currently doing a noise floor test (connect ref out to input) on my FA2. The initial (12 hour) results are REALLY good... ADEVs at long (10000+) tau are in the high E-15 range. I'll post results after I get 24 hours of data.
That annoying freq offset of the FA1 is gone. A 12 hour average of the FA2 freq readings is 10,000,000.000 001 Hz (FA2 clocked by a 5071A).
