Triggering
Explanation
This function activates a trigger when the N
th
time condition B becomes true after
condition A has become true.
Condition A and Condition B (Set Pattern)
Pattern of each channel:
CH1 to CH16, Logic A, or Logic B
Select from the following:
• CH1 to CH16 (Other Than Logic Inputs)
H: Above the preset trigger level
L:
Below the preset trigger level
X:
Don’t Care
• Logic Input
Enable:
Make the combination of the pattern
1
of each bit the trigger condition
Disable: Don’t Care
1 Select the pattern of each pattern from the following:
H:
Above a certain level
2
L:
Below a certain level
2
X:
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)
Condition
Select from the following:
Enter: A trigger is activated when all channels match the specified pattern.
Exit:
A trigger is activated when any of the channels no longer match the specified pattern.
Number of Times Condition B Is to Be Met (Count)
1 to 255 times
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
•
If you want to use a simple pattern trigger (only one pattern condition for activating the
trigger), set all of the status of condition B to Xs (Don’t care) and set a pattern for condition A.
•
If you want to set the trigger only on the condition of the pattern of each bit of the logic input
(trigger on the AND of each bit), then specify the following settings.
•
Condition A pattern
Set the logic input channels to be used to Enable and all other channels to X (Don’t care)
•
Condition B pattern
All Xs (Don’t care)
•
Bit pattern of logic input
Set arbitrarily.
