Settings panel (Pulse Width Trigger configuration menu) fields and controls.
Field or control Description
Source Lists the source channel or waveform to use to trigger or search. Types that require multiple
inputs will replace this control with a different source definition control.
Trigger When
■
< Limit: A pulse width is less than the specified time limit.
■
> Limit: A pulse width is greater than the specified time limit.
■
= Limit: A pulse width is equal to the specified time limit (±5%).
■
≠ Limit: A pulse width does not equal (is greater than or less than) the specified time limit
(±5%).
■
Inside Range: A pulse width is in the specified time range (±5%).
■
Outside Range: A pulse width is outside of the specified time range (±5%).
Level
Sets the amplitude level that the signal must pass through to be considered a valid transition.
Set to 50% Sets the threshold at 50% of the measured signal transition range. 50% is calculated as (Top +
Bottom)/2.
Time Limit Sets the time period condition to be met.
High Time Limit
(Trigger When = Inside Range
or Outside Range) Sets the longest acceptable pulse width time period for the range condition.
Low Time Limit
(Trigger When = Inside Range
or Outside Range) Sets the shortest acceptable pulse width time period for the range condition.
Polarity
Sets the polarity of the pulse to detect (positive pulse only, negative pulse only, or a positive or
negative pulse).
Logic Qualification Set to On to enable logic qualification to further refine the trigger condition by setting the
required logic conditions on the source signals to generate a trigger event.
Define Inputs Opens the Logic Qualification - Define Inputs dialog. Use this dialog to set the logic state,
threshold levels, and logic operation of the input signals. See
Logic Qualification - Define Inputs
configuration menu on page 400.
Available when Logic Qualification = On.
