Pattern Trigger
The Pattern trigger identifies a trigger condition by looking for a specified pattern.
This pattern is a logical AND combination of the channels. Each channel can have
a value of 0 (low), 1 (high), or don't care (X). A rising or falling edge can be
specified for one channel included in the pattern. You can also trigger on a hex
bus value as described on “Hex Bus Pattern Trigger" on page 132.
1 Press the [Trigger] key.
2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob to
select Pattern.
3 For each analog or digital channel you want to include in the desired pattern,
press the Channel softkey to select the channel.
This is the channel source for the 0, 1, X, or edge condition. As you press the
Channel softkey (or rotate the Entry knob), the channel you select is highlighted
in the Pattern = line directly above the softkeys and in the upper-right corner of
the display next to "Pat".
Adjust the trigger level for the selected analog channel by turning the Trigger
Level knob. Press the [Digital] key and select Thresholds to set the threshold level
for digital channels. The value of the trigger level or digital threshold is
displayed in the upper-right corner of the display.
4 For each channel you select, press the Pattern softkey; then, turn the Entry knob
to set the condition for that channel in the pattern.
