Explanation
This function activates a trigger the first time condition B becomes true after condition A
has become true and a preset time has elapsed.
Condition A and Condition B (Set Pattern)
Pattern of each channel: CH1 to CH16, Logic A, and 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.
Delay Time
0 to 10 s (resolution is 100 ns)
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
