[:SENSe]:DETector:TRACe[1]|2|3|4[:FUNCtion]?
Instruction
Specifies the detection mode. For each trace interval (bucket), average
detection displays the average of all the samples within the interval.

Parameter
Range
NEGative: Negative peak detection displays the lowest sample taken during
the interval being displayed.
POSitive: Positive peak detection displays the highest sample taken during
the interval being displayed.
SAMPle: Sample detection displays the sample taken during the interval
being displayed, and is used primarily to display noise or noise-like signals.
In sample mode, the instantaneous signal value at the present display point
is placed into memory. This detection should not be used to make the most
accurate amplitude measurement of non noise-like signals.
AVERage: Average detection is used when measuring the average value of
the amplitude across each trace interval (bucket). The averaging method
used by the average detector is set to either video or power as appropriate
when the average type is auto coupled.
NORMAL: Normal detection selects the maximum and minimum video signal
values alternately. When selecting Normal detection,”Norm”appears in the
upper-left corner.
QUASi: Quasipeak detection is a form of detection where a signal level is
weighted based on the repetition frequency of the spectral components
making up the signal. That is to say, the result of a quasi-peak measurement
depends on the repetition rate of the signal.
