: set the pattern of the channel selected to “H”, namely the voltage level is
higher than the trigger level of the channel.
: set the pattern of the channel selected to “L”, namely the voltage level is
lower than the trigger level of the channel.
: set the pattern of the channel selected to “Don’t Care”, namely this channel is

Trigger Condition:
Press When to select the desired trigger condition.
>: trigger when the duration of the pattern is greater than the preset time.
Press Time to set the duration of duration trigger and the range is from 8 ns to
10 s.
<: trigger when the duration of the pattern is lower than the preset time. Press
Time to set the duration of duration trigger and the range is from 8 ns to 10 s.
<>: trigger when the duration of the pattern is lower than the upper limit of the
preset time and greater than the lower limit of the preset time. Press Upper
Limit to set the upper limit of the duration of duration trigger and the range is
from 16 ns to 10 s. Press Lower Limit to set the lower limit of the duration of
duration trigger and the range is from 8 ns to 9.99 s.
Note: The time lower limit must be lower than the time upper limit.
Trigger Mode:
Press Sweep to select the “Trigger Mode” under this trigger type as auto, normal
or single. The corresponding status light of the current trigger mode turns on.
Trigger Setting:
Press Setting to set the trigger parameters (trigger holdoff and noise rejection)
under this trigger type.

Press Source to select CH1-CH4 respectively and use TRIGGER LEVEL to set
the trigger level of each channel. For details, please refer to the description of
“
