No, guy! The modulator is not the big box with the green display,
nor the small one on top of the first. It is the small board in the bottom
and it is connected to an HP-8563E spectrum analyser and an Agilent 33250A
arbitrary waveform generator for the measure of the unwanted side band
rejection.

SSB modulator” that I presented in September 2002 at the 4th D&RC
meeting in Renon (BZ), Italy.
