Explanation
This function activates a trigger on the OR logic of edge triggers. You can set trigger
conditions on all channels (CH1 to CH16) and DSP channels (DSP1 to DSP6 (option)).
For example, a trigger can be activated on the rising edge of CH1 or CH2.
Setting the Edge Trigger of Each Channel
Select from the following:
• CH1 to CH16 (Other Than Logic Inputs) or DSP1 to DSP6 (optional)
: 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:
700986: Approx. 1.4 V
700987: 6 V
±
50% (for DC input)
700987: 50 V
±
50% (for AC input)
Setting the Trigger Level
The trigger level setting applies to both simple and enhanced triggers.
For details, see “Setting the Trigger Level” in section 6.5.
Setting the 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
.
For details, see “Setting the Trigger Hysteresis” in section 6.5.
Setting the Hold Off
For details, see section 6.4, “Setting the Hold Off Time.”
Note
The OR trigger is equivalent to setting the pattern of condition A of Edge on A trigger to all Xs
(Don’t Care).
