Pattern Trigger
Identify a trigger condition by looking for a specified pattern. This pattern is a logical
“AND” combination of the two 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.

L
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 as the channel source for H, L, X or edge condition.
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 threshold level of the channel.

: set the pattern of the channel selected to “L”, namely the voltage level is
lower than the threshold level of the channel.

: set the pattern of the channel selected to “Don’t Care”, namely this channel is
not used as a part of the pattern. When both the channels in the pattern are set
to “Don’t Care”, the oscilloscope will not trigger.

or : set the pattern to the rising or falling edge of the channel selected.
