Parameters:
<mode> string
"POWer:AVG"
ContAv
After a trigger event, the power is integrated over a time interval
(averaging) set with SENS:POW:APER.
"POWer:TSLot:AVG"
Timeslot
The power is simultaneously measured in up to 26 time windows.
The number of time windows is set with SENS:POW:TSL:COUN.
The length of a time window is determined via
SENS:POW:TSL:WIDT. The measurement result is represented
by a vector that can contain up to 26 indices and contains the
power of a time window at each index.
"POWer:TGATe:AVG"
Timegate
The Timegate mode is a pseudo-mode. It is used to determine
accurate measured values in the gates defined with the aid of the
Trace mode in manual operation. If one of the four gates is
selected (SENS:TRAC:SEL), the sensor is internally put into the
Timeslot mode and configured such that it determines the average
power in this gate with high accuracy.
"POWer:BURSt:AVG"
Burst
In remote control, this measurement mode is very similar to the
ContAv mode. The integration time is, however, not predefined but
determined by the sensor with the aid of a burst detector. The start
of a burst is detected when the measurement signal rises above
the set trigger level. The end is set when the signal drops below
the trigger threshold. SENS:POW:BURS:DTOL defines the time
interval during which a signal drop below the trigger level is not
interpreted as the end of the burst. In the Burst mode, the set trig-
ger source is ignored and TRIG:SOUR INT is implicitly assumed.
"XPOWer:CCDF"
CCDF
The power in a settable time interval is measured and subse-
quently subjected to a statistical evaluation (CCDF). The mea-
surement time is set using the SENS:STAT commands. The
R&S NRP2 returns in response to READ? or FETCh? an array of
density values which are spread over the power axis. The value
range of the power axis is also set using the
SENS:STAT:SCAL:X commands.
CDF
The CDF does not represent a separate mode in the sensor. It is
calculated in the R&S NRP2 by way of the relation
CDF = 1-CCDF.
