7.2.1 Segmentation, Addressing and Resource Management
The R&S CMU and the R&S CMW500 both use a modular concept, with the instrument
functions grouped together in various "function groups" or "firmware applications". The
chief difference between the instruments is that R&S CMW500 does not use secondary
addressing.

Sub-instruments divide the instru-

7.2.2 RF Path Settings
The following settings control the routing of input and output signals, the correction of the
generator level or input power, the RF analyzer and the trigger system. The
R&S CMW500 provides more flexibility for connection control settings.
