Triggering
Explanation
Window Trigger Target
You can set trigger conditions on all channels (CH1 to CH16) other than logic waveforms. A
trigger occurs if any of the specified trigger conditions (OR condition) is met.
Trigger Condition (Set Pattern)
• CH1 to CH16 (Other Than Logic Inputs)
IN:
A trigger is activated when the trigger source enters the area between two
preset levels.
OUT: A trigger is activated when the trigger source exits the area between two
preset levels.
• Logic Input
Enable:
Make the combination of the status
1
of each bit the trigger condition
Disable:
Don’t Care
1 Select the status of each bit from the following:
:
When the signal goes above a certain level
2
:
When the signal goes below a certain level
2
– :
Don’t Care
2 Varies depending on the logic probe being used as follows:
702911/702912/700986: Approx. 1.4 V
700987:
6 V
±
50% (for DC input)
700987:
50 V
±
50% (for AC input)
Window (Center/Width)
A window is specified by a center level and width around the center level.
Selectable range of Center:
±
(Voltage range) when measuring voltage, measurement
range of the thermocouple when measuring temperature.
(Resolution: Same as the resolution of the trigger level. See
section 6.5.)
Selectable range of Width:
±
(Voltage range) when measuring voltage, measurement
range of the thermocouple when measuring temperature
around the center level.
(Resolution: Same as the resolution of the trigger level. See
section 6.5.)

Trigger Hysteresis
Sets a width to the trigger level so that triggers are not activated by small changes in the
trigger signal. Select the trigger hysteresis from

See section 6.4.
Notes for Activating Window Triggers
The operation is the same as the OR trigger for logic input.
