Source Setting
•
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.
–
If all channels in the pattern are set to
Don’t
care
, the oscilloscope will not trigger.

Limit Range
.
•
When the logic is
AND
or
NOR
, the time limit condition is available. This setting is particularly useful to filter
the hazard signals of combinational logic.
•
When the logic is
OR
or
NAND
, the time limit setting is not supported.
Holdoff, coupling, and noise reject can be set in edge trigger, see the sections
for more details.
