To shut down and turn off the R&S SMB100B
Risk of losing data
If you switch off the running instrument using the rear panel switch or by
disconnecting the power cord, the instrument loses its current settings. Fur-
thermore, program data can be lost.
Press the On/Standby key first to shut down the application properly.
1. Press the [On/Standby] key.
The current setup is saved, the operating system shuts down and sets the
instrument to standby state.
The [On/Standby] LED must be orange.
2. Turn off the main AC power switch at the rear panel of the R&S SMB100B
(position "0" (off)).
The instrument is no longer supplied with AC power.
Turning off the AC power
You can leave the AC power on permanently. Switching off is required only
if the instrument must be disconnected from all power supplies.
3.1.7 Functional Check
When the instrument is switched on, it automatically monitors the main functions.
A detected fault is indicated by an "Error" message displayed in the "Info" line of
the instrument together with a brief error description. For an in-depth identification
of the error, tap on the "Info" indication. In response, a description of the errors is
displayed. For more information, refer to the "Troubleshooting and Error Mes-
sages" section in the user manual.
Apart from the automatic monitoring, the R&S SMB100B provides internal adjust-
ments to check correct functioning. See the corresponding sections under "Main-
tenance" in the user manual.
