1 Introduction

Each test is explained in an example. Since each of the different measurements requires specific

settings, this application note includes a set of sample save files. The explanation in Section 1.1

describes how to create and recall such files.

The tests described here are limited to the ones that don’t need complicated external instruments,

such as spectrum analyzers and filters. Spurious measurements, transmitter intermodulation, and

out-of-band blocking tests, for example, are not covered. To see which other tests can be

performed when using such additional equipment, please always refer to the latest

R&S®CMW500 capability list, which can be found on the CMW customer web:

settings for the R&S®CMW500 parameters. Save files can also be used to easily move settings

from one R&S®CMW500 to another by storing the settings on the first device and then recalling

them on the target R&S®CMW500. For your convenience, this application note comes with a set

of save files for all the described tests.

To use them, begin by pressing the SAVE/RCL key on the top left of the R&S®CMW500’s front

panel.

Then follow the dialog prompts to locate your save files and select the one you want to recall.

Choose the desired file by pressing the Recall button on the top right of the screen. When

The duplex mode can only be selected at Signal OFF state.

For most test cases, the FDD and TDD test configurations and test steps are the same.

Differences in the individual tests are specified in this document.
