(12)-3 Mode
Sets the trigger comparison mode for each channel.
High: Condition where a trigger/alarm occurs when the input signal exceeds a set level.
Trigger (alarm) occurrence area
CH n
Low: Condition where a trigger/alarm occurs when the input signal exceeds a set level.
Trigger (alarm) occurrence area
CH n
Win in: Condition where a trigger/alarm occurs when for any channel, the upper and lower limit value is
set, and an input signal between those levels is input (when a signal is input).
Trigger (alarm) occurrence area
CH n
Win out: Condition where a trigger/alarm occurs when for any channel, the upper and lower limit value is
set, and an output signal between those levels is output (when a signal is output)

* These figures explain Trigger modes, but also work with alarm mode.
Detection of the trigger
To improve the detection rate of the trigger in the GL7000, the detection of the trigger is performed in the
following interval, regardless of the sampling interval.
Therefore, when the sample interval is slower than the following detection interval of the trigger, or the
measured signal is changed faster than the sample interval, the data at the trigger establishment may not
recorded, even if the trigger is successfully established.
<Trigger detecting interval>
• High Speed Voltage module (GL7-HSV) : 1 μs
• Voltage module (GL7-V)
• Voltage/Temperature module (GL7-M) : Sampling interval is 10 ms or less (10 ms).
• Logic/Pulse module (GL7-L/P)
• High Voltage module (GL7-HV)
