Depending on the installed baseband link option each firmware application instance can
access an arbitrary RX and TX signal path or only a fixed signal path. The available
baseband link options are the flexible link (R&S CMW-S550B/M) and the fixed link (R&S
CMW-S550A).
The following table lists the accessible RX and TX modules for an instrument with two
RX and TX signal paths.

Each RX and TX module is fix connected to one frontend and can only access the RF
connectors of this frontend.
For an instrument with two RX and TX signal paths and two frontends this results in the
following assignments:
●
RX 1: RF 1 COM, RF 2 COM
●
RX 2: RF 3 COM, RF 4 COM
●
TX 1: RF 1 COM, RF 1 OUT, RF 2 COM
●
TX 2: RF 3 COM, RF 3 OUT, RF 4 COM
Instrument with two RX and TX signal paths and one advanced frontend:
●
RX 1 / RX 2: RF 1 COM, RF 2 COM
●
TX 1 / TX 2: RF 1 COM, RF 1 OUT, RF 2 COM
4.1.2 Two Sub-Instruments
This section describes an instrument split into two sub-instruments. Each sub-instrument
is addressed separately and equipped with independent hardware and software resour-
ces in order to run the tasks assigned to it.
As an example, the instrument provides two RX and TX signal paths and two firmware
application instances. Each sub-instrument provides one RX and TX signal path and one
firmware application instance.
In manual operation mode one sub-instrument is visible at a time. The other sub-instru-
ment is active in the background but not visible at the GUI. This applies to all dialogs and
views. The
Generator/Signaling Controller Dia-
show and administrate only the firmware applications assigned to the current sub-
instrument.
The current sub-instrument can be identified by the string "Instrument 1" or "Instrument
2" in the window title and by the background color. In order to change the current sub-
instrument use the
In remote operation mode a remote channel addresses one sub-instrument. To control
two sub-instruments in parallel, two remote channels have to be set up.
