Glitch trigger
A glitch trigger occurs when the instrument detects a pulse narrower (or wider) than some specified time. You can set the
instrument to trigger on glitches of either polarity or to reject glitches of either polarity.
Pattern trigger
A pattern trigger occurs when the inputs to the selected logic function cause the function to become True or False. When you use
a pattern trigger, you define:
■
The precondition for each logic input: logic high, low, or "don't care"; the logic inputs are the instrument channels
■
The Boolean logic function: AND, NAND, OR, or NOR
■
The condition for triggering: the Boolean function becomes True (logic high) or False (logic low), and whether the True
condition is time qualified
Pattern trigger logic choices are summarized in the next table.
Pattern State Definition
1
,
2
AND
Clocked AND
If all the preconditions selected for the
logic inputs
3
are TRUE, then the
instrument triggers.
NAND Clocked NAND
If not all of the preconditions selected for
the logic inputs
4
are TRUE, then the
instrument triggers.
OR
Clocked OR
If any of the preconditions selected for the
logic inputs
5
are TRUE, then the
instrument triggers.
NOR
Clocked NOR
If none of the preconditions selected for
the logic inputs
6
are TRUE, then the
instrument triggers.
1
For state triggers, the definition must be met at the time the clock input changes state
2
The definitions given here are correct for the Goes TRUE setting in the Trigger When menu. If that menu is set to Goes False, swap the definition for AND with that for
NAND and for OR with NOR for both pattern and state types.
3
The logic inputs are channels 1, 2, 3, and 4 when using Pattern triggers. For State triggers, channel 4 becomes the clock input, leaving the remaining channels as logic
inputs.
4
The logic inputs are channels 1, 2, 3, and 4 when using Pattern triggers. For State triggers, channel 4 becomes the clock input, leaving the remaining channels as logic
inputs.
5
The logic inputs are channels 1, 2, 3, and 4 when using Pattern triggers. For State triggers, channel 4 becomes the clock input, leaving the remaining channels as logic
inputs.
6
The logic inputs are channels 1, 2, 3, and 4 when using Pattern triggers. For State triggers, channel 4 becomes the clock input, leaving the remaining channels as logic
inputs.
