Delayed Triggering
The TDS 600A Series oscilloscopes provide a main time base and a delayed
time base. The delayed time base, like the main time base, requires a trigger
signal and an input source dedicated to that signal. You can only use delay
with respect to the main edge trigger and certain classes of main pulse trig-
gers.
There are two different ways to delay the acquisition of waveforms:
delayed
runs after main
and
delayed triggerable
. Only delayed triggerable uses the
delayed trigger system.
Delayed runs
after main
looks for a main trigger, then waits a user-defined
time, and then starts acquiring (see Figure 3-12).

Delayed triggerable
looks for a main trigger and then, depending on the type
of delayed trigger selected, makes one of the three types of delayed trigger-
able mode acquisitions listed below (see Figure 3-13).
