Or drive the transverter input with an IF frequency signal generator.
The transverter being linear over some fair dynamic range should allow
varying the 10 GHZ output signal with the IF signal generator attenuator
limited by the maximum output of the transverter and the noise output of
the transverter on the low end.

Otherwise the LO can serve as a signal generator but it doesn't have
much frequency agility or built in attenuation. It needs a different
crystal, probably one on 96 MHz.
