Trigger Setup
Opens a dialog where you configure the trigger sequence. On the left, the first edge
trigger (A) is defined as usual. On the right, a second edge trigger (B) is defined with
the same parameters: source, level, edge, and hysteresis. The conditions of the B-trig-
ger are considered when the conditions of the A-trigger are met.
In addition, you can set a delay for the B-trigger ("Trigger").
Remote command:
Trigger
Sets a time delay or event delay for the B-trigger. The instrument waits for that delay
after an A-trigger until it recognizes the B-trigger.
"After time"
Sets the time the instrument waits until it checks the B-trigger condi-
tion.
"After events"
Sets a number of B-trigger events that fulfill the B-trigger condition
but do not cause the trigger. The oscilloscope triggers on the n-th
event, the last of the specified number of events.
Remote command:
6.6
Width trigger
The width trigger compares the pulse width (duration) with given time limits. It detects
pulses with an exact pulse width, pulses shorter or longer than a given time, and also
pulses inside or outside the allowable time range. The pulse width is measured at the
trigger level.
