Each of the four channels can be displayed, vertically positioned, and offset,
can have their bandwidth limited (100 MHz or 20 MHz) and their vertical
coupling specified. Fine gain can also be adjusted.
Besides the four channels, up to three math waveforms and four reference
waveforms are available for display. (A math waveform results when you
specify dual waveform operations, such as add, on any two channels; a
reference waveform results when you save a live waveform in a reference
memory.)
There are three horizontal display modes: main only, main intensified, and
delayed only. You can select among various horizontal record length settings
(see Table A-7).

Both the delayed only display and the intensified zone on the main intensified
display, may be delayed by time with respect to the main trigger. Both can be
set to display immediately after the delay (delayed runs after main mode); the
delayed display can also be set to display at the first valid trigger after the
delay (delayed-triggerable mode).
The delayed display (or the intensified zone) may also be delayed by a se-
lected number of events. In such a case, the events source is the delayed-
trigger source. For any events signal, the delayed-trigger system conditions
the signal by determining the source, coupling, etc., of that signal.
The triggering system is comprised of three types of signals for triggering the
signal acquisition system:
H
Edge (main- and delayed-trigger systems): This familiar type of triggering
is fully configurable for source, slope, coupling, mode (auto or normal),
and holdoff.
