Runt Search configuration menu
Use the Runt search to mark a waveform where a pulse crosses one threshold but fails to cross a second threshold before
recrossing the first threshold.
To create a new runt search:
1. Tap Add New... Search.
2. Set the Search Type to Runt.
3. Select the search Source.
4. Use the menu fields to set the search parameters.
To change the settings on an existing search, double-tap the search badge and make necessary changes.
Runt Search configuration menu fields and controls.
Field or control Description
Display Sets the display of the mark icons on or off. If you have multiple searches defined, the control
turns off just the marks for the selected search.
Stop Acquisition if Event
Found Stops input acquisition when the search event occurs. Default is not enabled.
Search Type
Set to Runt.
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.
Mark When
■
Occurs: A runt signal event occurs.
■
< Limit: A runt signal event occurs that has a pulse width less than the specified time limit.
■
> Limit: A runt signal event occurs that has a pulse width greater than the specified time
limit.
■
= Limit: A runt signal event occurs that has a pulse width that is equal to the specified time
limit (±5%).
■
≠ Limit: A runt signal event occurs that has a pulse width that does not equal (is greater
than or less than) the specified time limit (±5%).
Time Limit Sets the time period condition to be met.
Only available when Mark When = < Limit, > Limit, = Limit, or != Limit.
Polarity Sets the polarity of the pulse to detect (positive pulse only, negative pulse only, or a positive or
negative pulse).
Upper Threshold
Sets the upper threshold amplitude level through which the signal must pass to be considered a
valid transition.
Lower Threshold Sets the lower threshold amplitude level through which the signal must pass to be considered a
valid transition.
