EMI Protective Measures
In order to avoid electromagnetic interference, the instrument may only be operated when it is closed
and with all shielding covers fitted. Only appropriate shielded signal and control cables may be used.
Connecting the Instrument to the AC Supply
The network analyzer is automatically adapted to the AC supply voltage supplied. The supply voltage
must be in the range 100 V to 240 V; 50 Hz to 60 Hz. The mains connector is located at the bottom left
corner of the rear panel.
Connect the network analyzer to the AC power source using the AC power cable delivered with the
instrument.
The maximum power consumption of the analyzer is 450 W. The typical power consumption and the
frequency range of the individual analyzer models are listed in the data sheet.
The network analyzer is protected by two fuses as specified on the label on the power supply. The
fuses are located on an AC Fuse Board (order no. 1145.3906.02) which must be replaced to change
the fuses. Replacing the AC Fuse Board requires opening the instrument and is described in the
service manual.
