Trigger Level Settings/Alarm Level Settings
If the start side source setting or stop side source setting is "Level", specify detailed conditions for
each channel.
The overall structure of level triggers are as shown below.
<Trigger Level Settings> <Alarm Settings>
CH n Mode Level

Logic n Mode Level
CH n Mode Level
OrPulse n Mode Level

Logic n Mode Level
* Pulse and Logic are toggled back and forth.
* Specify an alarm output destination for Pulse and Logic for each channel.
The conditions are ORed for each alarm output destination.
Example) Suppose CH1 and CH2 are set to Output 1 and CH3 and CH4 to Output 2.
If either CH1 or CH2 meets the conditions, Alarm Output 1 occurs.
If either CH3 or CH4 meets the conditions, Alarm Output 2 occurs.
* Pulse and Logic are toggled back and forth.
Setting Description
(1) Combination Sets the combination of trigger conditions set for each channel.
Level OR :
Starts (stops) capturing data when at least one trigger condition is met.
Each condition is a level operation.
Level AND : Starts (stops) capturing data when all trigger conditions are met. Each
condition is a level operation.
Edge OR : Starts (stops) capturing data when at least one trigger condition is met.
Each condition is an edge operation.
Edge AND : Starts (stops) capturing data when all trigger conditions are met. Each
condition is an edge operation.
(2) Mode Specifies the mode for trigger comparison for each channel.
Of
f : Disables triggers for the set channel.
↑
H (Rising) : Generates a trigger when an input signal is above the specified level.
↓
L (Falling) : Generates a trigger when an input signal is below the specified level.
Win In : Generates a trigger when an input signal is (has come) between the
upper and lower limit levels set for each channel.
* There is no setting for a logic channel.
Win Out : Generates a trigger when an input signal is not (has moved out from)
between the upper and lower limit levels set for each channel.
* There is no setting for a logic channel.
(3) Level Specifies the level for trigger comparison.
Set one level for comparison if the mode is set to
↑
H (Rising) or
↓
L (Falling).
Set two levels for comparison if the mode is set to Win In or Win Out.
(4) Hold Generated Alarm Specifies the operation that occurs when the alarm conditions are met once and then
are no longer met.
