and
REFERENCE VALUE
softkeys the unit of the power
sensor display is changed from the absolut unit dBm or Watt to the relative unit dB or %. Use the
UNIT/SCALE
key if absolute units are required again.

DUTY
CYCLE
The DUTY CYCLE softkey opens a dialog to set the duty cycle to a percent
value for the correction of pulsemodulated signals. With the correction
activated, the sensor calculates the signal pulse power from this value and the
mean power. The softkey is highlighted if the correction is switched on.
Press the softkey again to switch the Duty Cycle correction off.
Valid entries are from 0.001 % to 99.999%; the stepsize is 0.1 %; the maximum
resolution for numerial entries is 0.001 dB. The default setting is 99.999%

Remote Control Commands
:[SENSe<1|2>:]PMETer:DCYCle:STATe
ON | OFF
This command controls the calculation of the signal pulse power from the mean power. The duty cycle
has to be set by SENS:PMET:DCYC:VAL according to characteristics of the input signal if the calculation
is switched on.
Example:
":SENS:PMET:STAT ON"
' activate power meter
":SENS:PMET:DCYC:STAT ON"
' switch the correction on
":SENS:PMET:DCYC:VAL 50.0"
' set the duty cycle to 50 %
