1.3.5 EMI Suppression
To suppress generated Electromagnetic Interference (EMI), operate the instrument
only while it is closed, with all shielding covers fitted. Note the EMC classification in the
data sheet.
Use appropriate shielded cables to ensure successful control of electromagnetic radia-
tion during operation, especially for the following connector types:
●
BNC rear panel connectors (10 MHz REF, EXT. TRIGGER): Use double shielded
cables and terminate open cable ends with 50 Ω.
●
USER CONTROL: Use only well shielded cables or disconnect the input pins of the
USER CONTROL connector in order to avoid spurious input signals which may
cause undesirable events. This is of particular importance for the external trigger
input (pin no. 2) if the EXT TRIGGER input is used.
●
USB: Use double-shielded USB cables and ensure that external USB devices com-
ply with EMC regulations.
●
GPIB (IEEE/IEC 625): Use a shielded GPIB cable.
●
LAN: Use CAT6 or CAT7 cables.
●
Test ports: For instruments with 3.5 mm connector types, use double-shielded
measurement cables.
The use of external accessories for the network analyzers may introduce additional
connector, cable, and cable length requirements. Refer to the relevant documentation.
1.3.6 Connecting the Analyzer 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 con-
nector 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 con-
sumption is listed in the "Specifications".
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.
1.3.7 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).
