To set pattern trigger
1. Press the Setup button to enter the TRIGGER menu.
2. Press the Type softkey. Turn the Universal Knob to select Pattern and then push the knob to
confirm.
3. Press the Source softkey to select each channel and press the softkey to the right to select
Don’t Care, High or Low for that channel.
 Low sets the pattern to low on the selected channel. A low is a voltage level that is less
than the channel's trigger level or threshold level.
 High sets the pattern to high on the selected channel. A high is a voltage level that is
greater than the channel's trigger level or threshold level.
 Don’t Care sets the pattern to don't care on the selected channel. Any channel set to
don't care is ignored and is not used as part of the pattern.
However, if all channels in the pattern are set to Don't Care, the oscilloscope will not trigger.
Adjust the trigger level for the selected analog channel by turning the trigger Level knob. An
Invalid channel doesn’t need its trigger level set.
4. Press the Next Page softkey to enter the second page of the pattern trigger menu.
5. Press the Logic softkey and turn the Universal Knob to select the desired logic combination
