Holdoff, Variable, Main Trigger
Minimum: For any horizontal scale setting, the
minimum holdoff for a
1x or 5x setting is 10 times
that setting, but is never shorter than 1
m
s or longer than 5 s. The
minimum holdoff for a 2.5x setting is 8
times that setting.
Maximum: For any horizontal scale setting, the
maximum holdoff is
at least 2 times
the minimum holdoff for that setting, but is never
longer than 10 times
the minimum holdoff for that setting.

Typical Signal Level for
Stable Triggering
Same as the DC-coupled limits for fre-
quencies above 60 Hz. Attenuates signals
below 60 Hz.
Three and one-half times the DC-coupled
limits.
One and one-half times the DC-coupled
limits from DC to 30 kHz. Attenuates sig-
nals above 30 kHz.
One and one-half times the DC-coupled
limits for frequencies above 80 kHz. At-
tenuates signals below 80 kHz.
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
w
2 division/ns.
2
The waveform interval (WI) is the time between the samples in the waveform record. Also, see the footnote for the characteris-
tics
Sample Rate Range or Interpolated Waveform Rates in Table A-9, on page A-14.
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.
