Each sub-instrument uses one specific frontend. The TX and RX module numbering is a
logical numbering per sub-instrument, not per instrument. That means e.g. that within
sub-instrument 1 the value TX1 refers to another physical TX module than within sub-
instrument 2.
The following table lists the supported parameter values and used *RST values for selec-
tion of RF connectors and TX/RX boards.

5.4.6 Resource and Path Management
The R&S CMW500 is a modular platform supporting a wide range of measurement, gen-
erator, and signaling applications. For the remainder of this section, all these applications
are termed "tasks".
In general, the instrument is capable of running several tasks in parallel. E.g. the GPRF
generator can be used to generate a test signal, while the GPRF Power measurement
analyzes the input signal at different powers and frequencies, and the External Power
Sensor measurement is used to monitor the signal power at a particular point in the test
setup. Conflicts between different tasks may occur if they rely upon the same system
resources.
The Resource and Path Management (RPM) of the R&S CMW500 represents a control
mechanism for conflicting tasks, deciding whether and for how long a running task will
persist.
Remote and manual control
The RPM principles described in this section are valid in remote as well as in manual
control. In remote control, running different tasks in parallel enhances the speed and
performance of the tester. In manual control, it allows you to monitor different measure-
ments simultaneously and compare the results.
