1
The trigger position errors are typically less than the values given here. These values are for triggering signals having a slew rate
at the trigger point of ±0.5 division/ns.
2
The waveform interval (WI) is the time between the samples in the waveform record. Also, see the footnote for the characteristics
Sample Rate Range and Equivalent Time or Interpolated Waveform Rates in Table 1Ć11 on page 1Ć12.
3
The minimum sensitivity for obtaining a stable trigger. A stable trigger results in a uniform, regular display triggered on the
selected 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.
