Define the "Find" Stage
InfiniiVision Oscilloscopes User's Guide
1 Press the Stage softkey and select Find:.
Find: is the first stage in the trigger sequence. When you select the Stage Find
softkey, the next softkey to the right will display Find: and give you a list of the terms
you can define for the Find stage. The Find stage can be set to one of the following
conditions:
•
Pattern 1 Entered — A pattern is entered on the last edge that makes the pattern
true (logical AND).
•
Pattern 1 Exited — A pattern is exited on the first edge that makes the pattern
false (logical NAND).
•
Edge 1
•
Pattern 1 and Edge 1
2 Press the Find: softkey and select the Find stage condition.
3 To define the term(s) used in the Find stage, press the Term softkey and select the
pattern and/or edge term displayed in the Find: softkey.
4 If you select a pattern term, each channel in the pattern must be set to a 1 (high),
0 (low), or X (don't care).
a Press the Channel softkey (or rotate the Entry knob) to select the channel.
As you select a channel, the channel is highlighted in the selected pattern list
shown in the waveform area and is also shown in the upper-right corner of the
display next to "Seq"
b Press the 0 1 X softkey to set a level for the channel.
•
1 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.
•
0 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.
•
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. 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. Press the [D15-D0] 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.
c Repeat for all channels in the pattern.
