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 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.

Description
Display
Sets the display of the mark icons on or off.
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 amplitude level through which the signal must pass to be considered a valid transition.
Lower Threshold
Sets the lower amplitude level through which the signal must pass to be considered a valid transition.
Copy Trigger Settings to
Search
Sets the search criteria to match the current oscilloscope trigger settings. If the trigger settings are not
valid in Search, this control is either not available or grayed out.
