VENTS
Select a positive or negative slope and a number of events. An event is the
number of times the trigger condition is met after the last trigger. A trigger
is generated when the condition is met after this number, counted from
the last trigger. The count is restarted on each trigger. For example, if the
event number is two, the trigger occurs on the third event.
Edge Trigger with Holdoff by Events (in this example, two events). The bold edges
on the trigger source indicate that a positive slope has been selected. The broken,
upward-pointing arrows indicate potential triggers, while the bold ones show
where triggers actually occur after the holdoff expires.
Auxiliary Input Trigger
Some instrument models provide auxiliary input trigger capability. It's done
as a pattern trigger, on the Ext dialog.
Select X1, or ÷10. You can also select from DC50Ω, Gnd, and DC1MΩ
Impedance values.
