Switches between the Memory trigger, Start trigger, or Memory block menu
(2) Channel: Selects the TRIGn source channel.
(3) Detection: Selects UP, DOWN, INTO WIN, or OUT WIN for the polarity of the trigger signal.
UP The trigger is detected when the value exceeds the trigger level (threshold).
DOWN The trigger is detected when the value is below the trigger level (threshold).
INTO WIN The trigger is detected when the value enters the range of the upper limit
value or lower limit value of the trigger level.
OUT WIN The trigger is detected when the value leaves the range of the upper limit
value or lower limit value of the trigger level.
(4) Threshold: Sets the trigger level (threshold).
For INTO WIN / OUT WIN, there are two settings: the upper threshold and lower threshold.
(5) Filter: Sets the filter time for noise removal.
(6) Close: Ends the setting operation and returns to the trigger list.
CAUTION
The trigger level is a value relative to the set measurement range. The value also changes when the
measurement range is changed.
(Example) When the trigger level is set to 10 mV when the range is 100 mV, and then the
measurement range is changed to 200 mV, the trigger level is changed to 20 mV.
