To start the R&S SMA100B
Starting the R&S SMA100B requires that it is connected and turned on.
► At the front panel, press the [On/Standby] key briefly.
The instrument boots the operating system and starts the instrument firmware.
After booting, the instrument is in the state before the last power off (standby
or ready), indicated by the color of the [On/Standby] key's LEDs:
● Green: the R&S SMA100B is running and ready for operation.
All modules are power-supplied.
● Orange: the R&S SMA100B is in standby mode (main AC power switch is
in position "I").
The standby power mode keeps the power switch circuits and the oven-
controlled crystal oscillator OCXO active. In this state, it is safe to switch
off the AC power and disconnect the instrument from the power supply.
To switch between standby and ready state, briefly press the [On/Standby]
key.
If a previous session was terminated regularly, the instrument uses the last setup
with the relevant instrument settings.
► To set up a new configuration, press the [Preset] key to return the instrument
to its defined reset/preset state.
To shut down and turn off the R&S SMA100B
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.
