To start the analyzer, proceed as follows:
1. Switch the AC power switch to position
I
(On).
After power-on, the analyzer automatically goes to standby or ready state, depend-
ing on the state of the standby toggle key at the front panel when the instrument
was switched off last time.
2. If necessary, press the standby toggle key on the front panel to switch the instru-
ment to ready state (R&S

from amber to green).
The analyzer automatically performs a system check, boots the Windows
®
operat-
ing system and then starts the network analyzer (VNA) application. If it was termi-
nated regularly, the VNA application restores all recall sets and instrument settings
of the previous analyzer session.
To shut down the analyzer, proceed as follows:
1. Press the standby key.
This will cause the instrument to save all loaded recall sets, close the VNA applica-
tion, shut down Windows
®
, and go to standby state. Of course you can also per-
form these steps manually, like in any Windows session.
2. If desired, set the AC power switch to position
O
(Off).
