Detector Type
The analyzer displays the sweeped signal on the screen in the form of trace.
For each trace point, the analyzer always captures all the data within a specific
time interval and processes (Peak, Average,etc.) the captuered data using the
detector currently selected, then display the processed data (one point) on the
screen .
Key Points:
 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, RMS Avg,
Voltage Avg and Quasi-Peak. The default is Pos Peak.
 The corresponding icon (as shown in the figure below) of the detector type
selected is displayed in the status bar at the left side of the screen.
1. Pos Peak
For each trace point, Positive Peak detector displays the maximum value of
data sampled within the corresponding time interval.
2. Neg Peak
For each trace point, Negative Peak detector displays the minimum value of
data sampled within the corresponding time interval.
