Specifying an Edge in a Pattern
N O T E
You are allowed to specify only one rising or falling edge term in the pattern. If you define an
edge term, then select a different channel in the pattern and define another edge term, the
previous edge definition is changed to a don't care.

Hex Bus Pattern Trigger

You can specify a bus value on which to trigger. To do this, first define
the bus. See
You can trigger on a bus value whether you are displaying the bus or not.

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.
the condition for that channel in the pattern.
0 sets the pattern to zero (low) on the selected channel. A low is a
•
voltage level that is less than the channel's trigger level or threshold
level.
1 sets the pattern to 1 (high) on the selected channel. A high is a
•
voltage level that is greater than the channel's trigger level or
threshold level.
X 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.
• The rising edge ( ) or falling edge ( ) softkey sets the pattern to an
edge on the selected channel. Only one rising or falling edge can be
specified in the pattern. When an edge is specified, the oscilloscope
will trigger at the edge specified if the pattern set for the other
channels is true.
If no edge is specified, the oscilloscope will trigger on the last edge
that makes the pattern true.
