Hi Rod,

I tried OTM and it works but not as good as we have seen
before. It also requires a gain setting between 50 and 200
to have any effect. Has Brad changed some scaling things?
This signal must be high passed filtered, maybe he changed
something in the filter circuit. Any ideas?

Rod, a question: The spectrum analyzer uses volt/volt scaling
for PSD values, what is it really telling me in volts?
I know it is power verses frequency but how do the volts
figure into this? If we look at acceleration the units are
G's or gal not volts. Maybe you should just tell me how the
PSD function is scaled. Thanks.

Best regards,
Terry
