That is great news that your KC901V is back repaired - well done.
You can see signals above 0dBm by going into the level (amplitude) menu and setting the reference level to 20dBm.
Th R3465 will handle up to 30dBm max but I would keep below 20dBm (100mW)
The maximum level I have seen out of my unit is 14dBm.

Good suggestions. I hope that this site starts to be more proactive with members.
In addition I suggest:-
5. The maximum 30kHz limit is a hardware limited but the lower limit of 1kHz could be even lower, though i realise this affects overall span observed. Then again in the application of observing modulation on a carrier, you are looking at signals close-in. I suggest including 300Hz and 100Hz as lower bandwidth options so that Bessel functions (carrier drop out points) can be observed as part of calibration checks for FM deviation with 1kHz mod source.
That way you can resolve and observe the carrier from the FM side bands.
