7 GPRF Applications
The General Purpose RF (GPRF) firmware applications provide an RF test and
measurement functionality that is not related to a particular network standard. The R&S
CMW 500 provides the following GPRF firmware applications:

GPRF Measurements
7.1 GPRF Measurements and Generators
General Purpose RF (GPRF) measurements determine the properties of an arbitrary
RF signal. The R&S CMW 500 provides the following GPRF measurements:
Power
External Power Sensor
In addition the R&S CMW 500 can generate an RF signal for test purposes.
GPRF RF Generator
7.1.1 General Purpose RF Generator
The General Purpose RF (GPRF) generator provides a flexible RF signal for test
purposes. The R&S CMW 500 provides several independent RF generator modes:
In constant-frequency mode the RF generator provides a single or dual-tone RF
signal at constant frequency.
In arbitrary mode, the RF signal is based on an arbitrary baseband signal defined
by a waveform file (*.wv, ARB File).
In list mode, the RF generator steps through a list of configurable frequencies and
levels.
The RF generator signal can be routed to any of the RF connectors at the front panel
of the instrument. Moreover, it is possible to take into account a constant external
output attenuation for the RF generator signal in order to compensate for a known loss
or gain in the test setup.
7.1.1.1 GPRF Generator (Constant Frequency)
In constant-frequency mode the RF generator provides a single or dual-tone RF signal
at constant frequency and output level.
The single-tone (CW) signal is configured with its level and frequency. No further
signal settings are needed.
The two sources of the dual-tone signal can be configured separately; see below.
