Dear Glenn,

As far as I remember, the RA6793A scale is in decibel-microvolt, with 
3 vertical bars for every 10 dB, to a maximum of 120 dB.

Due to a quirk (actually a design blunder) in the definition of the 
decibel, the amount in decibel is doubled for voltages as compared to 
powers.  Furthermore, the impedance of your source must be matched to the Rx.

Keeping all this in mind, 10 microvolt amounts to 20 dB, 100 
microvolt to 40 dB, 1 mV to 60 dB etc., and 120 dB to 1 V.

Hope this helps.
