Pattern Trigger
Identify a trigger condition by looking for a specified pattern. This pattern is a logical
“AND” combination of the valuesof the four channels. Each channel can have a value
of high (H), low (L) or don’t care (X). A rising or falling edge can be specified for one
channel included in the pattern. When an edge is specified, the oscilloscope will
trigger at the edge specified if the pattern set for the other channel is true (H or L). If
no edge is specified, the oscilloscope will trigger on the last edge that makes the
pattern true. If both the channels in the pattern are set to “Don’t Care”, the
oscilloscope will not trigger.

Trigger Type:
Press Type to select “Pattern”. At this point, the trigger setting information as shown
in the figure below is displayed at the upper right corner of the screen.
Channel Selection:
Press Source to select CH1-CH4 respectively. The current signal source is displayed
at the upper right corner of the screen.
Pattern Setting:
Press Code to set the pattern of the current channel. At this point, the pattern
setting area (as shown in the figure below) is displayed at the bottom of the screen.

: 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.
