6.13 Setting the B>Time, B<Time or B Time Out
Trigger (ENHANCED)
≡
For a description of this function, refer to page 1-9.

Function
B>Time : Trigger occurs when condition B goes false after holding true for the preset pulse
width.
B<Time : Trigger occurs when condition B goes false after holding true for less than the
preset pulse width.
B TimeOut : Trigger occurs when condition B has held true for the preset pulse width.
When B > Time, CH1 = H, Time = 4

Channel H/L status for condition B
Same as for A
→
B(n) trigger (H/L/X). For details refer to page 6-10.
Channel to use for condition B: Source
The channels that can have trigger conditions set are CH1 to CH16. The trigger occurs when all
conditions are met.
The channel that has the logic input module installed cannot set condition B.
Pulse width
B>Time, B Time Out : 200 ns to 1 s (The setting resolution is 100 ns)
B<Time : 200 ns to 1 s (The setting resolution is 100 ns)
B>Time, B<Time and B TimeOut setting precaution
• Correct operation is not guaranteed if adjacent pulses are less than 200 ns apart or if pulse
width is less than 200 ns (typical).
200 ns or more
• The B>Time, B<Time and B TimeOut trigger cannot be used on channels which have logic
input modules installed.
Other settings
Refer to sections 6.1 to 6.7 for details on how to set the trigger mode, trigger level, coupling,
HF rejection, and holdoff time.
