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 650 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.
Power on and off
The mains connector is located at the bottom left corner of the rear panel.
To turn the power on or off, press the AC power switch to position I (On) or 0 (Off).
After power-on, the analyzer is in standby or ready state, depending on the state of the STANDBY
toggle switch at the front panel of the instrument when the instrument was switched off for the last time.
The AC power switch can be permanently on. Switching off is required only if the instrument
must be completely removed from the AC power supply.
