figure below. You can also press Type continuously to select the trigger type or
enable the touch screen to tap the desired trigger type and select it.
Source Selection:
Press Source to open the signal source list and select CH1-CH4 or D0-D15. For
details, refer to descriptions in "Trigger Source". The current trigger source is
displayed at the upper-right corner of the screen.
Note: Only when we select the channel (that has been input with signals) as the
trigger source, can we obtain a stable trigger.
Pattern Setting:
Press Code, and rotate the multifunction knob to select the pattern of the
currently selected channel. Press down the knob to select the pattern. The
corresponding pattern is displayed at the bottom of the screen. The patterns of
channels CH1-CH4 and D0-D15 are presented from left to right, as shown in the
figure below. You can also press Code continuously to select the pattern or enable
the touch screen to select it.
 H: sets the pattern of the channel selected to "H", i.g. the voltage level is higher
than the trigger level/threshold level of the channel.
 L: sets the pattern of the channel selected to "L", i.g. the voltage level is lower
than the trigger level/threshold level of the channel.
 X: sets the pattern of the channel selected to "X", i.g. this channel is not used as
a part of the pattern. When all channels in the pattern are set to "X", the
oscilloscope will not trigger.
Trigger Condition:
Press When, then rotate the multifunction knob to select the trigger condition,
and then press down the knob to select the trigger condition. You can also press
When continuously to select the trigger condition or enable the touch screen to tap
the desired trigger condition and select it.
 >: triggers when the duration of the pattern is greater than the preset time.
Press Lower to set the lower limit of the duration of the pattern. Its range is
from 800 ps to 10 s.
 <: triggers when the duration of the pattern is smaller than the preset time.
Press Upper to set the upper limit of the duration of the pattern. Its range is
from 800 ps to 10 s.
 <>: triggers when the duration of the pattern is smaller than the upper limit of
the preset time and greater than the lower limit of the preset time. Press Upper
to set the upper limit of the duration of the pattern, and the range is from 1.2 ns
to 10 s. Press Lower to set the lower limit of the duration of the pattern, and
the range is from 800 ps to 10 s.
