5 = Sensor input connector of the R&S NRX
6 = R&S NRX base unit

Incorrectly connecting/disconnecting the R&S NRPxxTWG power sensors can damage
the power sensors or lead to erroneous results.
Ensure that you connect/disconnect your power sensor as described in

Chapter 3,

"Preparing for Use"

on page 11.

Starting a measurement

1. Preset the R&S NRX and the connected R&S power sensors.

a) Press the [Preset] key.
b) Tap "Preset".

All parameters are set to their defaults.

2. If measuring in zero-IF mode (RBW

> 40

MHz), consider to zero the power sensor:

Note:

Turn off all measurement signals before zeroing. An active measurement

signal during zeroing causes an error.

a) Switch off the power of the signal source.
b) Press the [Zero] key of the R&S NRX.
c) Tap "Zero All Sensors".

3. Configure the measurement.

a) In the "Measurement Settings" dialog, select the "Measurement Type", for

example "Continuous Average".

b) Tap "Quick Setup"

> "Auto Set".

4. Switch on the signal source.
