1 Preface
The operation of the R&S CMW is described in several user manuals:
●The R&S CMW user manual describes the base software, common features of the
firmware applications and basic principles for manual operation and remote control.
●Additional user manuals, like this document, describe the firmware applications.
Rohde & Schwarz provides registered users a "CMW Customer Web" section on
GLORIS, the Global Rohde & Schwarz Information System: https://extranet.rohde-
schwarz.com. From this resource you can download software updates, waveform library
updates and documentation updates, e.g. updates of this document.
1.1 How to Read Firmware Application Chapters
Each firmware application is described in a separate chapter. These chapters can be
read independently of each other. However, they are all organized as follows:
1. General Description
2. Application Sheets (optional)
3. GUI Reference
4. Programming Examples
5. Command Reference
The chapters "System Overview" and "Remote Control" in the R&S CMW user manual
provide additional important information independent of the individual firmware applica-
tions. The most important parts are referenced by the firmware application descriptions.
1.1.1 General Description
This section provides a general description of the firmware application, independent of a
specific operation mode (manual or remote control). It gives a high-level introduction to
the capabilities of the firmware application. Background information related to the network
standard is given as far as it is directly related to administrable parameters. For mea-
surement applications a detailed description of measurement results and a description
of configurable limits is given, including the relation to conformance requirements defined
in network standard specifications.
1.1.2 Application Sheets
This optional section provides short application examples for select issues and related
background information.
