Standard Dialogs
The standard dialog for setting up an analog Pattern trigger includes all the controls for setting the pattern
and the voltage threshold on the same dialog.
1. Select the Boolean Operator (AND, NAND, OR, or NOR) that describes the relationship among analog
inputs (e.g., C1 must be High NAND C2 must be Low).
2. For each input to be included in the trigger pattern, and select what State it must be in (High, Low, or
Don't Care) compared to the threshold Level you will set. Leave "Don't Care" selected for any input you
wish to exclude.
3. For each input included in the trigger, enter the voltage threshold Level.
4. Use Time Condition is settings to specify how long the pattern must persist for the trigger to fire. This
may be:
l Any time Less Than an Upper Value.
l Any time Greater Than a Lower Value.
l Any time In Range or Out Range of values. You may describe the range using either:
l Limits, an absolute Upper Value and Lower Value.
l Delta, any Nominal width plus or minus a Delta width.
