sinusoidal (spectral) components. Peak detection obtains the maximum
video signal value between the last display point and the present
display point and stores this value in memory. Peak detection is

corner of the display. Sample detection is used primarily to display
noise or noise-like signals. This detection should not be used to make
the most accurate amplitude measurement of non noise-like signals. In
sample mode, the instantaneous signal value at the present display
point is placed in memory. Sample detection is activated automatically
for noise level markers or during averaging.
Negative peak detection functions the same as peak detection, but
selects the minimum video signal value. When
