Trigger
Delay Trigger Mode
Delay Softkey
The delay softkey selects between delay by time and delay by count. Delay
time disables the trigger circuit for a selected period of time, from 30 ns to
160 ms after the trigger is qualified.
Time delay is not available in the time qualified pattern settings of when
present greater than, when present less than, and when present for a range
of times. Delay count (delay by edges) disables the trigger circuit for a
selected count from 1 to 16,000,000 after the trigger is qualified. After the
selected count is met, the oscilloscope looks for the selected trigger edge.
Trigger On Softkey
The trigger on softkey selects a specific edge to trigger on after the
qualification and delay conditions are met. All the other softkeys in this
menu dealt with defining qualifying conditions. The trigger on softkey
sets the trigger point. You can select the number of counts, slope, and source
for the trigger event.
