safety class I, it must only be connected to an outlet that has a ground contact.
Characteristics of the AC power supply:
●
100 V to 240 V AC
●
50 Hz to 60 Hz; 400 Hz
●
3.5 to 1.6 A, 2HU height unit (R&S SMAB-B92)

2.1.1.6 Turning the Instrument On and Off
To turn on the R&S SMA100B
1. Connect the instrument to the AC supply.
2. Turn on the main AC power switch at the rear panel of the R&S SMA100B (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 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-control-
led 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.
