Standby and Ready state

The ON/STANDBY key is located in the bottom left corner of the front panel.

Switching between standby and ready state
 

Press the ON/STANDBY key briefly to switch the instrument from the standby to ready state or vice versa.

 

In ready state, the left, green LED is on. The instrument is ready for operation. All modules are power-supplied and the R&S SMA initiates its startup procedure.

In standby state, the right, yellow LED is on. The standby power only supplies the power switch circuits and the oven-controlled crystal oscillator to keep it at its operating temperature. In this state it is safe to switch off the AC power and disconnect the instrument from the power supply.
