Trigger methods

Pattern

Edge

Edge/pattern combinations













Continuous

Mouse/Keyboard

  

"1", "0" and "don’t care" conditions selectable on all channels
On any one channel. Rising edge, falling edge, or change of state
Edge and pattern triggering may be activated together for single captures or for conditionally continuous capture.

Edge and pattern trigger combinations:
edge up
edge down
edge up OR edge down (Change-of-state)
pattern
pattern OR edge up/down/change-of-state
pattern AND edge up/down/change-of-state
pattern THEN edge up/down/change-of-state
edge THEN pattern up/down/change-of-state
pattern < duration (glitch capture), ± 20ns, 1ms max
pattern > duration, ± 20ns, 1ms max
Unconditionally: Screen updates at regular intervals
Conditionally: Display updates on set trigger condition
A trigger may be forced
Extended capture time
 Varies depending on sampling rate:
200MHz: 10ms max ... 1.25KHz:1677 sec max.
