Crest Factor - Digital Impairments
Indicates the crest factor of the baseband signal.
The crest factor is calculated from the two level parameters as follows:
Crest[dB]=Peak_Power[dBFs]/Signal_Power[dBFs]
Remote command:
[:SOURce<hw>]:BB:CFACtor?

Peak Power - Digital Impairments
Indicates the peak power of the baseband signal relative to full scale of 0.5 V (in terms
of dB full scale).
Remote command:
[:SOURce<hw>]:BB:POWer:PEAK?
