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 CMW 500 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 below 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
measurements simultaneously and compare the results.
5.4.8.1 Basic RPM Principles
The principles of R&S CMW 500 Resource and Path Management can be summarized
very briefly:
Non-conflicting tasks can be running in parallel without restriction.
A new measurement or generator that is in conflict with a running task replaces the
running task. Conflicting measurements are blocked until the generators are
switched off by other means.
Generators are released immediately, measurements are released after the
current measurement cycle.
According to the last rule, conflicting measurements are queued. A new measurement
is started only after all previous measurements have been terminated in a regular way.
The RPM principles can be visualized as follows:
