NOTICE!

Incorrectly connecting or disconnecting the power sensor can damage

the power sensor or lead to erroneous results. Ensure that you connect or discon-
nect the power sensor as described in

Chapter 3.4, "Connecting to a DUT"

on page 14.
Connect the power sensor to the signal source.

2. Connect the cables as shown in

Figure 5-4

If the power sensor is a R&S

NRP LAN power sensor, you can set up a LAN con-

nection instead of using the sensor input connector of the R&S

NRX. See

Chap-

ter 3.7.3, "Using a LAN connection"

on page 20.

Starting a measurement

For a detailed description of how to measure in this setup, refer to the user manual of
the R&S

NRX.

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.

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".
