2.3.5 EMI Protective Measures
To avoid electromagnetic interference, the unit may only be operated when it is closed
and with all shielding covers fitted. Use only appropriate shielded signal and control
cables; see
chapter 2.1.3, "RF Connectors"
, on page 8. Observe the EMI classifications
of both the R&S
ZVAX24 and the R&S ZVA24 in their data sheets.
Electrostatic discharge
To protect the extension unit against Electrostatic Discharge (ESD) damage use the wrist
strap and grounding cord supplied with the network analyzer and connect yourself to the
GND connector at the front panel. For details refer to the Quick Start Guide of your ana-
lyzer.
2.3.6 Connecting the Extension Unit to the AC Supply
The extension unit is automatically adapted to the AC supply voltage. 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 rear panel.
► Connect the extension unit to the AC power source using the AC power cable deliv-
ered with the unit.
The maximum and typical power consumption of the extension unit is listed in the data
sheet. The extension unit is protected by two fuses which can be replaced as described
in
chapter 2.3.9, "Replacing Fuses"
2.3.7 Power on and off
The mains connector and switch is located at 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 extension unit is in standby or ready state, depending on the state of
the standby key at the front panel of the unit.
2.3.8 Standby and Ready State
The standby key connects/disconnects all internal modules of the extension unit to/from
the DC supply voltage generated by its internal power supply.
