Chapter 5 To Trigger the Oscilloscope

Pattern Trigger

Identify a trigger condition by looking for a specified pattern. This pattern is a logical
"AND" combination of channels. Each channel can have a value of high (H), low (L),
don't care (X), rising or falling edge. When a rising or falling edge is specified for one
channel, the oscilloscope will trigger at the edge of the specified channel if the input
signals for other channels are consistent with the pattern currently set. If no edge is
specified, the oscilloscope will trigger on the last edge that makes the pattern true. If
all channels in the pattern are set to "Don't Care", the oscilloscope will not trigger.
Trigger Type:
Press Type, rotate
trigger setting information is displayed at the upper right corner of the screen.
For example,
trigger source is CH1; the trigger level is 0.00 V.
Source Selection:
Press Source to open the signal source list and select CH1-CH4 or D0-D15. The
current trigger source is displayed at the upper right corner of the screen.
Pattern Setting:
Press Code to set the pattern of the current signal source. At this point, 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.
: 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 not used as a part of the pattern. When all 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.
