None of my two 5065A's have particular good A1's, so I don't know
what the baseline performance should be like.
I have been playing with this DDS (Hi Bo! :-)
And it gives quite an improvement for me.
My plan is to replace the entire chain up to the 60 MHz with that
DDS, and do the modulation digitally, then put one of those
"geophone/optical" 24bit ADC's on the photo-sensor and close the loop.
