3.4 Sub-Instruments
An instrument with several RX and TX signal paths can either be used as one (sub-)instru-
ment or it can be split into several sub-instruments which operate independently. This
section provides basic information related to both modes.
In the factory default configuration, all resources are grouped together in a single sub-
instrument. Splitting the instrument can help to run tasks in parallel, and minimize the risk
of resource conflicts between these tasks.

3.4.1 One Sub-Instrument
This section describes an instrument with all resources grouped together in a single sub-
instrument. As an example, the instrument provides two RX and TX signal paths and two
firmware application instances.
The instances are distinguished by the suffixes 1 and 2, e.g. in the "Measurement Con-
troller" dialog or in window titles.
For remote control the instances are also distinguished by these suffixes. All firmware
applications can be controlled using the same remote channel. In the "Remote Set-
tings" of the "Setup" dialog the sub-instrument is identified as "Assigned Instrument" = 1.
The table below summarizes these assignments. The firmware applications GPRF Gen-
erator and GPRF Power are listed as examples. The instances of all other firmware
applications are assigned in the same way.

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.
