Trigger level settings/Alarm level settings
Specifies detailed conditions for each channel when the start and stop side source settings are Level.
The configuration of the level trigger is as shown in the figure below.
* Pulse and Logic are switchable.

* Pulse and Logic are switchable.
* Specify an alarm output destination for each channel and Pulse/Logic.
Each of the alarms is ORed at the output destination.
Example: If you specify 1 as the output destination of 1CH and 2CH and 2 as that of 3CH
and 4CH, Alarm Output 1 occurs when one of 1CH and 2CH meets the conditions,
and Alarm Output 2 occurs when one of 3Ch and 4CH meets the conditions.

Description
(1) Combination
Set the combination of the trigger condition set for each channel.
Level OR: Starts (stops) capturing when a set trigger condition is satisfied.
The level operation is determined by each condition.
Level AND: Starts (stops) capturing when all the set trigger conditions are satisfied.
The level operation is determined by each condition.
Edge OR: Starts (stops) capturing when a set trigger condition is satisfied.
The each operation is determined by each condition.
Edge AND: Starts (stops) capturing when all the set trigger conditions are satisfied.
The each operation is determined by each condition.
* Only for trigger setting.
(2) Mode
Set the mode to compare trigger/alarm for each channel.
Off: Trigger/alarm of set CH is disabled.
H (Rising): Trigger/alarm is established when the input signal exceeds the set level.
L (Falling): Trigger/alarm is established when the input signal is lower than the set level.
Window In: Trigger/alarm is established when the input signal is within the range between
the upper level and lower level.
* Logic CH has no setting.
Window Out: Trigger/alarm is established when the input signal is out of the range between
the upper level and lower level.
* Logic CH has no setting.
(3) Level
Set the level to compare trigger/alarm.
Set the comparison level to one place when the mode is H (Rising) or L (Falling).
Set the comparison level to two places when the mode is Window In or Window Out.
(4) Output
Set the alarm output CH when an alarm occurs.
* Only for alarm setting
* The operation in parentheses () is for edge operation.
* When the alarm is set, the level operation is fixed.
