On/Standby key and standby LEDs
The standby LEDS and the ON/STANDBY key are located in the bottom right corner of
the front panel. The ON/STANDBY key toggles the R&S
NRP2 between standby and
ready state, indicated by the standby LEDs.
The standby LEDs indicate the current instrument state:
●
Yellow LED (AC supply)
The yellow LED indicates that the R&S NRP2 is power supplied and in standby
mode.
●
Green LED (ON)
The green LED indicates when the meter is on, i.e. ready for operation.
The possible operating states are:
The meter is off and disconnected from the AC supply.
The meter is on standby. The AC supply is connected and the power supply is operat-
ing correctly.
The meter is on and is being powered from the AC supply.
1.5.4 Connectors
To the left of the display, the R&S NRP2 provides a power reference signal connector
and two sensor connectors.
If option R&S NRP-B5 is installed, the R&S NRP2 offers two sensor ports at the rear.
Thus, you can perform measurements with a maximum of 4 connected sensors simul-
taneously.
POWER REF
The POWER REF connector (option R&S NRP-B1/-B7, sensor check source) provides
a high-precision sine signal with a power of 1 mW and a frequency of 50 MHz for
checking the sensors. Option R&S NRP-B7 additionally comes with a pulse mode of
the test signal with a modulation frequency of 10 kHz.
Chapter " Sensor Check Source" describes how the generator is turned on and off.
