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 FSP 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 FSP 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

Limit lines are defined and displayed irrespective of the sweep ranges, i.e. they are

not part of the sweep ranges. The unit of the limit lines is restricted to dB or dBm.
