POWer:FORWard:AVERage:BURST
Average Burst Power
IThis term is used for pulsed RF signal to define the average
carrier power within the burst. The average burst is equal to the
PEP (Peak Envelope Power) value if the burst is unmodulated
and has no overshoots. The NRT2 measures the average burst
power by multiplying the average power with the ratio of burst
period to burst width. The two burst parameters must either be
user-defined or the ratio is automatically determined by the
NRT2. Manual entry of the parameters is possible any time and
the sensors NRT-Z43/44 also allow automatic measurement.
POWer:FORWard:PEP
Peak Envelope Power
This is the periodically recurring peak value of the carrier power
at maximum modulation. The PEP is an important parameter for
describing the modulation characteristics of transmitter output
stages. The level difference between PEP and AVG may be
between 0 dB (CW signal) and some 10 dB (radar bursts).
POWer:FORWard:CCDFunction
CCDF
This function provides information about the probability of the
peak envelope power exceeding a preset threshold. It is suitable
e.g. for assessing the power distribution of spread-spectrum sig-
nals (CDMA or similar). The sensors NRT-Z43/44 provide this
function. The video bandwidth can be selected.
POWer:ABSorbtion:AVERage
Average Absorbed Power
This function Indicates the difference between forward and
reverse power.
POWer:ABSorbtion:AVERage:BURSt
Average Absorbed Burst Power
This function Indicates the difference between forward and
reverse power (burst).
POWer:ABSorbtion:PEP
Absorbed Peak Envelope Power
This function Indicates the difference between forward and
reverse power (PEP).
POWer:REVerse
Reverse Power
Reverse power (in W or dBm. according to power indication).

POWer:AVG
[SENSe<Sensor>:][POWer:][AVG:]APERture[:VALue]
<integration_time>
Determines the integration time for a single measurement in the ContAv mode. To
increase the measurement accuracy, this integration is followed by a second averaging
procedure in a window with a selectable number of values. The filter window is config-
ured with the
[SENSe<[1]..4>]:AVERage
commands.
