I managed to borrow a Tek TDS 2024B 200 MHz scope from work and hooked
it up to the output of my MV89A. I get a peak-to-peak measurement of
2.3 V which if I have converted it right is ~11 dBm ? Alternatively if
I turn on the FFT mode on the scope I get a peak value of -2.17 db if
I am driving the cursor mode correctly. With the 10 MHz from the
radioshackus GPSDO used for triggering, it takes ~18 seconds for the
MV89 waveform to drift 1 cycle (this is without anything connected on
the Uin or Uref pins).
