"No trigger": if all the channels are in this mode, the device records indefinitely.
•
"Lower than": triggering takes
place when the signal drops
below the threshold.
•
"Lower/higher than": triggering
takes place when the signal
drops below or rises above the
threshold.
•
"Higher than": triggering takes
place when the signal rises
above the threshold.
•
"Outside window": triggering
takes place when the signal goes
outside the window defined by
the two thresholds.
A half-division hysteresis is applied to prevent ill-timed triggers.
- Channel 1 is set with a 1.25V "higher than" trigger.
- Channels 2 and 3 do not wait for a trigger.
- Channel 4 is set with an "outside" type trigger.
- Channel 1 and 4 lines are highlighted: they wait for a trigger.
Toggle through the trigger conditions for the different channels using the key
shown opposite.
If this option is activated, all the traces acquired are saved to a .REC file as
soon as the acquisition memory is full, then acquisition is restarted.
Delayed triggering offers the possibility of starting up an acquisition at a date
and time chosen by the user.
This option can be related to the previous trigger conditions.
