Sequential Triggering
In applications that involve two or more signals, you may be able to use
sequential triggering to capture more complex events. Sequential triggering uses
the A (Main) trigger to arm the trigger system, and then uses the B (Delayed)
trigger to trigger the oscilloscope if a specific condition is met. You can choose
one of two trigger conditions:
H Trigger After Time: After the A trigger arms the trigger system, the
oscilloscope triggers on the next B -trigger event that occurs after the trigger
delay time. You can set the trigger delay time with the keypad or the
multipurpose knobs.
H Trigger on nth Event: After the A trigger arms the trigger system, the
oscilloscope triggers on the nth B event. You can set the number of B events
with the keypad or the multipurpose knobs.
NOTE. The traditional delayed trigger mode called “Runs After” is served by the
TDS5000 feature Horizontal Delay. You can use horizontal delay to delay
acquisition from any trigger event, whether from the A (Main) trigger alone or
from a sequential trigger that uses both the A (Main) and B (Delayed) triggers.
See Triggering with Horizontal Delay On on page 3-- 93 for more information.
Keep in mind the following when using sequential triggers.
Trigger Sources. In most cases, you will set separate trigger sources for the A
(Main) and B (Delayed) triggers.
Trigger Types. Sequential triggering for Trigger after Time or Trigger on nth
Event is available for the Edge, Glitch, and Width types. It is not available for
the rest of the trigger types.
The B trigger is always the Edge type.
