2.2.3 Detect
The analyzer displays the sweep signal on the screen in the form of a trace. For each trace
point, the analyzer always captures all the data within a specific time interval and processes
(Peak, Average, etc.) the data using the detector currently selected, then it displays the
processed data (a single data point) on the screen.
Select an appropriate detector type according to the actual application in order to ensure the
accuracy of the measurement.
The available types are Pos Peak, Neg Peak, Sample, Normal, Average and Quasi Peak.
The default is Pos peak.
1. Positive Peak
For each trace point, Positive Peak detector displays the maximum value of data sampled
within the corresponding time interval.
2. Negative Peak
For each trace point, Negative Peak detector displays the minimum value of data sampled
within the corresponding time interval.
3. Sample
For each trace point, Sample detector displays the transient level corresponding to the central
time point of the corresponding time interval. This detector type is applicable to noise or
noise-like signal.
4. Normal
Normal detector (also called rosenfell detector) displays the maximum value and the minimum
value of the sample data segment in turn: Odd-numbered data points display the maximum
value and even-numbered data points display the minimum value. In this way, the amplitude
