Connecting to the AC Power Supply
The R&S NRX can be used with different AC power voltages and adapts itself auto-
matically to them. Adjusting the R&S NRX to a particular AC supply voltage is therefore
not required. Refer to the data sheet for the requirements of voltage and frequency.
The power switch can be set to two positions:
●
[0]: The instrument is disconnected from the mains.
●
[I]: The instrument is power-supplied. It is either ready for operation (STANDBY) or
in operating mode.
1. Plug the AC power cable into the AC power connector on the rear panel of the
R&S NRX. Only use the power cable delivered with the R&S NRX.
2. Plug the AC power cable into a power outlet with ground contact. The R&S NRX
complies with safety class EN61010-1.
The required ratings are listed next to the AC connector and in the data sheet.
