The table below summarizes these assignments. All assignments are fixed. The firmware
application instances of the two sub-instruments are named identically, but are inde-
pendent of each other.

Assigned Instrument = 1
Assigned Instrument = 2
Each signal path and RF connector is fix assigned to one specific sub-instrument. The
RX and TX modules of both sub-instruments are named identically but refer to different
physical modules.
For an instrument with two RX and TX signal paths and two frontends, each sub-instru-
ment contains one RX module, one TX module and three RF connectors. If two RX and
TX signal paths and only one advanced frontend are available, one sub-instrument con-
tains two RF connectors and the other sub-instrument one RF connector. For more details
refer to the following table.

4.2 Generators
A generator provides a configurable RF signal for test purposes. The R&S CMW500
provides the "General Purpose RF" (GPRF) generator and generators for various network
standards.
All generator applications are similar in structure, although the generated signals differ
in many of their properties. The following topics describe common features of the gen-
erators. For a sample session refer to
4.2.1 Generator Control
Generators can be in the "ON" or "OFF" states. In the default configuration, all generators
are switched off; no output signal is available. The generator state is shown in the gen-
erator control softkey.
