Preparations
Setting the trigger level
When the trigger type is set to “Level” (level of signal at input connector),
the actual level to be used as a trigger level must be set as a percentage
[%] of the full-scale value of the current input range.
Make the setting using the “Level” item in <Trigger> menu. The actual
trigger level is indicated on the bar graph for the trigger channel (see
page 26).
Setting the trigger channel
When the trigger type is set to “Level”, the channel to be used as trigger
channel must be set.
Make the setting using the “Ch” item in <Trigger> menu.
The indication “TRG” is shown at the left of the trigger channel. (For
information on level trigger target channel indication, see page 24).
Setting the start and stop time
When the trigger type is set to “Time”, set the start time and stop time
as follows.
Make the setting using the “Start Time” and “Stop Time” items in <Trigger>.
Note
When the start time setting is before the current time,
the setting automatically becomes “current time +
5 minutes”. When the stop time setting is before
the current time, the setting automatically becomes
“Start Time + 24 hours”.
