2. Turn on the main AC power switch at the rear panel of the R&S SMB100B
(position "I" (on)).
The instrument is supplied with AC power.
Warm-up time for OCXO
When the instrument is switched on, the OCXO requires an extended
warm-up time (see data sheet).
To start the R&S SMB100B
Starting the R&S SMB100B 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 SMB100B is running and ready for operation.
All modules are power-supplied.
● Orange: the R&S SMB100B 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.
