Unit just arrived. Initial testing does not agree with original complaint: "Output at 2Ghz is -10db below what it should be. Won't produce a signal much past 10Ghz and at 10Ghz it is -30db below the RF output level setting. No output past this frequency"
Output is approximately 5 dB below stated level, from 2 to 20 GHz. At the AUX output, I measure also 5 dB low, or -5 dBm, rather than 0 dBm.
With the ALC disabled, output is around 18 dBm, which might also be low (not sure).
So it seems I'm about 5 dB low across the board. Maybe YIG output is weak OR perhaps the MOD/Coupler...?
At any rate, may not be as bad as expected.
Next, open 'er up!
