Time-Out Trigger - UNI-T UPO2102 User Manual

User's Manual
(1) Delay Condition
Set delay condition to >, <, <>, ≤≥, >< .
a. >：It will be generated when the time difference (△T) between the edge of source 1 and the edge
of source 2 is greater than the setting lower limit of time, it can set the lower limit of time.
b. <：It will be generated when the time difference (△T) between the edge of source 1 and the edge
of source 2 is smaller than the setting upper limit of time, it can set the upper limit of time.
c. ≤≥：It will be generated when the time difference (△T) between the edge of source 1 and the edge
of source 2 is greater than the setting lower limit of time and smaller than the setting upper limit
of time, it can set the upper limit and lower limit of time.
d. > <：It will be generated when the time difference (△T) between the edge of source 1 and the
edge of source 2 is smaller than the setting lower limit of time or greater than the setting upper
limit of time. It can set the upper limit and lower limit of time.
(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 7-7.
(1) Edge Type
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.
