Fig. 3-2: SSB modulated generator signal
You can now tap the RF generator signal with the selected properties at the RF1 COM
connector. For an instructive configuration check, you can connect RF1 COM to RF2
COM using a coax cable and observe your signal using the "GPRF Power" measurement;

ARB generator
The GPRF dual-tone signal is an example for a real-time generator signal. As an alter-
native, the GPRF generator application provides the arbitrary ("ARB") baseband mode.
The ARB generator signal is based on a "waveform file" which is loaded and processed
at runtime. For details refer to the "GPRF Generator" description.
3.2.2 Measuring an RF Signal
The R&S CMW500 provides various general purpose and network-specific measure-
ments. All measurements are controlled in an analogous manner. The following example
uses the General Purpose RF (GPRF) Power measurement.
The GPRF Power measurement measures a series of power steps at (possibly) different
powers and frequencies and performs a statistical evaluation. As a simple example we
can measure the RF signal generated by the GPRF generator of the R&S CMW500. The
signal is tapped at the RF1 COM connector and measured at RF2 COM.
1. Configure the GPRF generator as described in
.
2. Connect a coax cable between the two RF connectors RF1 COM and RF2 COM at
the front panel of the R&S CMW500 to ensure that the generator signal is fed to RF2
COM.
