2.24.3.13.1 Normal PSA Only: 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 of CW signals
accurate.
When Normal is selected, Norm appears on the left side of the display.

Remote Command:
See “Detector 2” on page 224.
2.24.3.13.2 Average PSA Only: 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) is set to Pwr
Avg, and Detector is set to Avera ge, the RMS method is selected.
When Average is selected, Avg appears on the left side of the display.
