(2) The upper/lower limit of time
Compare the setting time value with
△
T, it will be triggered when the condition is met. The range can
be set 8ns ~ 10s.
7.9 Time-out Trigger
Timeout trigger can generate the signal when the time interval (
△
T) from the rising edge (or falling edge)
of the input signal to adjacent falling edge (rising edge) across the trigger level is greater than the set
timeout time. As shown in Figure 7-6.
Figure 7-6
(1) Slope
Select which edge that the input signal can be triggered. It can select rising edge, falling edge,
random rising. The current slope is displayed in the upper right corner of the screen.
a. Rising edge
：
Set the timer to start when the rising edge of the input signal through the trigger
level.
b. Falling edge
：
Set the timer to start when the falling edge of the input signal through the
trigger level
.
c.
Random edge
：
Set the timer to start when the rising edge or the falling edge of the input
signal through the trigger level
.
(2) Timeout
Compare timeout with
△
T, it will be triggered when the condition is met. The range can be set 8ns
~ 10s.
