Note about Faceless Instruments
Chapter 1 of this manual gives an overview of the front panel controls and connectors
of the R&S CMW 500 Wideband Radio Communication Testers with display and gives
all information that is necessary to put the instrument into operation and connect
external devices. The application examples in Chapter 2 and the following chapters are
also based on a R&S CMW 500 with display.
The measurement functionality of the two instrument types is identical. You can test all
measurement examples reported in this manual using an R&S CMW 500 without
display that is controlled from the Graphical User Interface displayed on an external
monitor or PC.
For specific information concerning faceless instruments refer to your quick start guide.
