Preparing the Analyzer for Use

Shock hazard

The instrument is still power-supplied while it is in standby mode.

1.3.9 Replacing Fuses

The DC inputs PORT BIAS at the rear panel are each protected by a fuse IEC 127 - F
250 L (250 mA quick acting).

► To replace the fuses open the fuse holder by slightly turning the lid counterclock-

wise.

Replacement fuses are provided with the instrument.

1.4 Starting the Analyzer and Shutting Down

To start the analyzer, proceed as follows:

1. Make sure that the instrument is connected to the AC power supply and the power

switch on the rear panel is in position I (On).

2. If necessary, press the STANDBY toggle switch on the front panel to switch the

instrument to ready state (the green LED is on).

In ready state, the analyzer automatically performs a system check, boots the Win-
dows

operating system and then starts the network analyzer (NWA) application. If the

last analyzer session was terminated regularly, the NWA application uses the last
setup with all instrument settings.

To shut down the analyzer, proceed as follows:

1. Press the STANDBY key to save the current setup, close the NWA application,

shut down Windows

and set the instrument to standby state. Of course you can

also perform this procedure step by step like in any Windows session.

2. If desired, set the AC power switch to position 0 (Off).
