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.
