• <> (Out of Range) – when the pattern is present for a time outside of
range of values.
Pattern durations are evaluated using a timer. The timer starts on the
last edge that makes the pattern (logical AND) true. Except when the
Timeout qualifier is selected, the trigger occurs on the first edge that
makes the pattern false, provided the time qualifier criteria has been
met.
The time values for the selected qualifier are set using the qualifier
time set softkeys (< and >) and the Entry knob.
4 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.
5 For each channel you select, press the Pattern softkey; then, turn the
Entry knob to set the condition for that channel in the pattern.
