order harmonic distortion = 2
nd
order harmonic measurement value – base waveform
measurement value
For example, when the output waveform frequency of the channel is 10MHz, if the base
waveform measurement value is 0.8dBm and the 2
nd
order harmonic measurement value
is -56.2dBm, the 2
nd
order harmonic distortion = (-56.2) -0.8=-57dBc<-55dBc and the
test result fulfills the specification requirement.
