This performance verication test must be performed with the EMC analyzer set
in the spectrum analyzer mode.
A 50 MHz CW signal is applied to the INPUT 50 of the analyzer through
two step attenuators . The attenuators increase the eective amplitude range
of the source . The amplitude of the source is decreased in 10 dB steps and
the analyzer marker functions are used to measure the amplitude dierence
between steps . The source's internal attenuator is used as the reference
standard. The test is performed in both log and linear amplitude scales .
