SENSe:AVERage:RESet
SENSe:AVERage:RESet initializes the averaging filter for the Continuous Average, Burst Average or
Timeslot Average modes. This is useful if a high averaging factor is set in the SENSe:AVERage
:TCONtrol MOVing filter mode and if the power to be measured has significantly decreased since the
previous measurement, e.g. by several powers of ten. In this case, previous measurement results still
contained in the averaging filter strongly affect the settling of the display; as a result, the advantage of
t
he SENSe:AVERage:TCONtrol MOVing filter mode, i.e. the ability to detect trends in the measurement
result while the measurement is still in progress, is lost. The SENSe:AVERage:RESet command solves
this problem by deleting all previous measurement results that the averaging filter contains. After
initialization, the filter length gradually increases from 1 to its nominal value SENSe:AVERage:COUNt,
so that trends in the measurement result become quickly apparent. However, this procedure does not
shorten the measurement time required in order for the averaging filter to settle completely.
SENSe:AVERage:STATe[?] OFF | ON
SENSe:AVERage:STATe switches on or off the averaging filter for the Continuous Average, Burst
Average and Timeslot Average modes.
The query yields
• 1 for OFF,
• 2 for ON.
Default setting: ON
SENSe:AVERage:TCONtrol[?] MOVing | REPeat
SENSe:AVERage:TCONtrol (terminal control) defines the behaviour of the averaging filter in the
Continuous Average, Burst Average and Timeslot Average modes. As soon as a new measured value
is shifted to the FIR filter, a new average value is available at the filter output, which is obtained from
the new measured value and the other values stored in the filter.
The MOVing parameter defines that each new average value is output as a measurement result. This
allows tendencies in the result to be recognized during the measurement procedure.
The REPeat parameter defines that a new result is output after the FIR filter has been filled with new
measured values. This ensures that no redundant information is output.
The query yields
• 1 for MOVing,
• 2 for REPeat.
Default setting: REPeat
SENSe:CORRection:DCYCle[?] 0.001 to 99.999
SENSe:CORRection:DCYCle sets the duty cycle to a percent value for the correction of pulse-
modulated signals. With the correction activated, the sensor calculates the signal pulse power from this
value and the mean power. Since the duty cycle is only useful in the Continuous Average mode, it is
evaluated only there.
The query yields the current duty cycle in percent.
Default setting: 1.0 [%]
