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. |
