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).
