nect the power sensor as described in

Chapter 3.4, "Connecting to a DUT"

on page 12.
Connect the power sensor to the signal source.

2. Connect the power sensor to the computer as shown in

Figure 5-1

For a detailed description, refer to

Chapter 3.7.1.1, "Simple USB connection"

on page 14.

Starting a measurement

For a detailed description of how to measure in this setup, refer to the operating man-
ual of the R&S

NRPV.

1. Start the R&S

NRPV.

2. Execute zeroing.

Note:

Turn off all measurement signals before zeroing. An active measurement

signal during zeroing causes an error.

3. Switch on the test signal of the signal source.

4. Start a measurement.

R&S

Power Viewer

The R&S

Power Viewer is software that simplifies many measurement tasks. It is provi-

ded on your documentation CD-ROM and on the Rohde & Schwarz website as a sepa-
rate standalone installation package.
