Hum Rejection
(Option 05 Video Trigger)
NTSC and PAL: –20 dB without any trigger spec deterioration. Triggering will continue
down to 0 dB with some performance deterioration.
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 or Interpolated Waveform Rates in Table 1–4, on page 1–10.
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.
