The minimum sensitivity for obtaining a stable trigger. A stable trigger results in a uniform, regular display triggered on the seĆ
lected slope. The trigger point must not switch between opposite slopes on the waveform, and the display must not roll" across
the screen on successive acquisitions. The TRIG'D LED stays constantly lighted when the SEC/DIV setting is 2 ms or faster but
may flash when the SEC/DIV setting is 10 ms or slower.
