1.5 Starting and Shutting down the Analyzer
To start the analyzer, proceed as follows:
C
If you use the AC power supply, make sure that the instrument is connected to the
mains supply and switch the power switch on the rear panel to position I (On).
C
If you use the DC power supply, make sure that the instrument is connected and
press the power on/off key on the front panel.
The analyzer automatically performs a system check, boots the Windows XP operating
system and then starts the 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:
C
With AC power supply, press the power on/off key to save the current setup, close
the NWA application, shut down Windows XP and set the instrument to standby or
off state, depending on the
SETUP -> More -> Shutdown Off/Standby
settings.
Refer to section
Instrument States with AC Power Supply
. From the standby state,
you can set the AC power switch to position 0 (Off) to turn the analyzer completely
off..
C
With DC power supply or battery, press the power on/off key to switch the analyzer
off.
Power on/off key, OCXO
Do not press the power on/off key longer than 3 seconds.
The AC power switch also interrupts the power supply of the OCXO (option OCXO
Reference Frequency, R&S FSL–B4). When you switch the instrument back on, be
sure to comply with the extended warm–up phase specified in the data sheet.
Saving instrument settings
When using the AC power supply, it is strongly recommended to press the power on/off
key on the front panel before disconnecting the power. If you set the power switch on
the rear panel to 0 while the NWA application is still running, you will lose the current
settings. Moreover, loss of program data can not be excluded if the application is
terminated improperly.
With DC power supply or battery, it is safe to switch off the instrument using the power
on/off key on the front panel.
