2.3.1.2 Normal
Displays the peak-detected level in the interval (bucket) being displayed when the signal is
CW-like. If the signal is noise-like (within a bucket the signal both rose and fell), the even
bucket shows the peak (maximum) within a two-bucket interval, and the odd bucket shows
the negative peak (minimum). Gain is increased to compensate for the effects of faster
sweep rates, to keep the displayed value accurate.
When Normal is selected, Norm appears on the left side of the display.
Key Path: Det/Demod
Remote Command:
See “Detector” on page 95
Example: DET NORM
2.3.1.3 Average
For each interval (bucket) in the trace, Average detection displays the average of all
samples within the interval using one of the following averaging methods:
•log (also known as video)
•power (also known as RMS)
•voltage envelope
To explicitly set the averaging method, use the BW/Avg,Avg/VBW Type key. The combination
of the average detector and the power method is equivalent to what is sometimes referred
to as “RMS detection.” When the method (Avg/VBW Type)issettoPwr Avg,andDetector is set
to Average, the RMS method is selected.
When Average is selected, Avg appears on the left side of the display.
Key Path: Det/Demod,Detector
Dependencies/
Couplings: Use of Average affects the VBW setting. See BW/Avg,VBW.
When in Average detection, video trigger is not available.
