Pattern Trigger
Pattern trigger mode identifies a trigger condition by looking for a specified pattern. The pattern
trigger can be expanded to incorporate delays, similar to other triggers. Pattern durations are
evaluated using a timer. The timer starts on the last edge that makes the pattern “true”. Potential
triggers occur on the first edge that makes the pattern false, provided that the time qualifier criterion
has been met. The oscilloscope provides 4 patterns: logical AND, OR, NAND and NOR combination
of the channels. Each channel can set to low, high or invalid.
To trigger on a pattern:
1.
Press
Trigger Setup
on the front panel to enter the TRIGGER function menu.
2.
Press the
Type
F key; turn the
Universal Knob
to select
Pattern
, and then push down the knob
to confirm.
3.
Press the
Source
F key to select
channel, and then press the level type F key to select
Don’t care
,
High
or
Low
.
l
Low
sets the pattern to low on the selected channel.
Low
means the channel’s voltage is
less than its trigger level.
l
High
sets the pattern to high on the selected channel. A
High
voltage is greater than the
channel's trigger level.
l
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.
l
Note: 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 pressing
Trigger Level
and
turning the
Universal Knob
.
Don’t care
channels don’t need their trigger levels set.
4.
Press the
Next Page
F key to enter the second page of the pattern trigger menu.
5.
Press the
Logic
F key and then turn the
Universal Knob
to select the desired logic combination
AND
,
OR
,
NAND
or
NOR
.
6.
Press the
Time
F key; then turn the
Universal Knob
to select the desired time value.
