selects between positive peak, sample, and negative peak detection. Negative
peak detection is only available with option 101. When sample detection is
selected, SMPL appears in the upper-left corner of the screen. 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, during
video averaging, and for FFT measurements.
When positive peak detection is selected, PEAK appears in the upper-left
corner of the screen. Positive peak detection obtains the maximum video
signal between the last display point and the present display point and stores
this value in the trace memory address. Positive peak detection is selected at
power on and by pressing (PRESET].
Negative peak detection functions the same as positive peak detection but
selects the minimum video signal. The PEAK message does not appear in the
upper-left corner of the screen.
