Connecting the Instrument to the AC Supply
The R&S FSMR is equipped with an AC voltage selection feature and will automatically adapt itself to
the applied AC voltage (range: 100 to 240 V AC, 40 to 400 Hz). External voltage selection or adaptation
of the fuses are not necessary. The AC power connector is located on the rear panel (see below).
