Triggering
Explanation
This function activates a trigger on the OR logic of edge triggers. You can set trigger
conditions on all channels (CH1 to CH16). For example, a trigger can be activated on the
rising edge of CH1 or CH2.
Edge Trigger of Each Channel (Set Pattern)
Select from the following:
• CH1 to CH16 (Other Than Logic Inputs)
: Rising edge
: Falling edge
–: Don’t Care
• 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)
Trigger Level
The trigger level setting applies to both simple and enhanced triggers.
See “Trigger Level” in 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
, , and .
See “Trigger Hysteresis” in section 6.5.
Hold Off
See section 6.4.
Note
The OR trigger is equivalent to setting the pattern of condition A of Edge on A trigger to all Xs
(Don’t Care).
