Triggering the Oscilloscope 4
6000 Series Oscilloscope User’s Guide 143
To use Pattern triggering
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 high (H), low
(L), don't care (X). A rising or falling edge can be specified for
one channel included in the pattern.
1 Press the Pattern key in the Trigger section of the front panel
to display the Pattern trigger menu.

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 H, L, X, or edge condition.
As you press the
Channel softkey (or rotate the Entry knob on
mixed-signal oscilloscopes), 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
“

”. External trigger may also be specified as a channel in
the pattern when using the 2-channel and 4-channel
oscilloscopes.
