Thus, two measurements with different level settings are performed in the follow-
ing example. First, a high reference level is used on the carrier frequency, and
then a low reference level is used on the frequency of the third harmonic.
The default setting of the R&S
FSVA/FSV for measurements ("SetupInstrument")
is also used as a starting point here, after which adaptations for the measurement
are carried out.
