•When the trigger setting is the external trigger (
EXT
), measurement is performed once
with the falling (
DOWN
) or rising (
UP
) edge of the TRIG

. The edge direction can be set in
the
SET
screen. (Initial value: Falling [
DOWN
])
See "Disabling the trigger input during measurement and setting the trigger input effective
edge" (p. 182). (Falling: HI→LO, rising: LO→HI)
•
The TRIG signal is invalid when the trigger source is set to the internal trigger (
INT
).
See "Trigger (perform measurements with user-defined timing) (Common)" (p. 63).
