Tracking generator
The frequency of the internal generator can be coupled to the input frequency of the
analyzer, so that the input signal for the DUT tracks (or follows) the input signal of the
analyzer. This function is referred to as a tracking generator.
Frequency coupling is useful for test scenarios for which a signal generator is required,
but an additional instrument is too expensive or takes up too much space.
When using the internal generator as a tracking generator, the R&S
FPL1000 also
allows you to set a frequency offset for frequency-converting measurements.
Using the internal generator as a tracking generator is only available in the Spectrum
application for frequency sweeps. If you switch to another application, a currently
active tracking generator is disabled.
Power sweep
For a power sweep measurement, the internal generator signal remains at a fixed fre-
quency, but increases its power level within a specified range over time. The default
frequency of the internal generator is coupled to the (center) frequency of the analyzer
and can be set from 5
kHz to the maximum frequency of the R&S
FPL1000. However,
you can define an offset for the internal generator frequency.
