Remote command:
CALCulate<Measurement>[:CHANnel<Channel>]:FEED<Channel>
"POWer:FORWard:AVERage"
CCDF ← Forward
Complementary cumulative distribution function. Probability that the envelope power is
higher than the threshold set under
Suitable for assessing the power distribution of spread-spectrum signals, for example
CDMA.
Remote command:
CALCulate<Measurement>[:CHANnel<Channel>]:FEED<Channel>
"POWer:FORWard:CCDFunction"
Peak Envelope Power (PEP) ← Forward
Peak power of an amplitude-modulated signal. Depending on the selected
, this parameter allows detecting short-time overshoots at the beginning of a
burst.
The peak envelope power (PEP) is an important parameter for describing the modula-
tion characteristics of transmitter output stages.
Remote command:
CALCulate<Measurement>[:CHANnel<Channel>]:FEED<Channel>
"POWer:FORWard:PEP"
Absorption Average ← Forward
Absorbed average power. Difference between the forward and reverse
mea-
surement.
