I recently ran into a problem using PSDR/VAC/WINMOR.. The Winmore two
tone test produced unstable ( braking up ) output from PSDR and the
Flex.. After some trial and error, I discovered that the output became
stable if I change the VAC "Ms per int" from the default of 7 to 8..
This may have something to do with fact that my PSDR sample rate of
48000 becomes a integer number of samples per int at 8 ( 48000
samples/sec / 8 Ms per int ) = 6000 samples / int ). At 7 it's, 48000/7
= 6857.14....
( on the other hand 44100 / 7 = 6300 )
If anyone concurs, I would recommend changing VAC setup recommendation
to 8 Ms per int.
