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 of CW signals accurate.

When Normal is selected, Norm appears on the left side of the display.

State Saved: Saved in Instrument State.

Remote Command: See “Detector 2" on page 371.

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) is set to

Pwr Avg, and Detector is set to Average, the RMS method is selected.

When Average is selected, Avg appears on the left side of the display.
