9Measuring Spurious Emissions - R&S ESU Series Operating Manual

R&S ESU
4.8.13.9 Measuring Spurious Emissions
All real amplifiers also generate unwanted RF products outside the assigned fre-
quency band. These spurious emissions are usually measured across a wide fre-
quency range, for example from 9 kHz to 7 GHz. The analyzer settings are specified
for each frequency range.

In the Spurious Emissions measurement mode, the R&S ESU performs measure-
ments in predefined frequency ranges with settings that can be specified individually
for each of these ranges.
For this purpose, the SWEEP TABLE settings or the current device settings are
used. Up to 20 subranges can be defined (they need not directly follow one another)
across which the R&S ESU sweeps in subsequent order. However, the measure-
ment ranges must not overlap. The measurement parameters can be selected inde-
pendently from each other in every subrange (SWEEP LIST menu, EDIT SWEEP
LIST).
