Measurement
Setting on analyzer:
AMPT/MIXER/MIXER LVL MANUAL –5 dBm
First the level is measured at the test frequency as reference, th
en a
s
ignal is searched for at the analyzer frequency.
The nonharmonic spacing is the measured level referred to the
reference level (dBc = referred to the carrier).
Note:
Some of the nonharmonics suppression values to be measured are
outside analyzer specifications. In case of doubt, the measurement
should be repeated with a 3 dB attenuator at the analyzer input. If
the nonharmonic spacing changes, the nonharmonic comes from
the analyzer.
Recommended settings and sampling frequencies:
Nonharmonics of the synthesis without option R&S B22 at test level 3.0 dBm, unmodulated
