Field or control Description
Trigger 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%).
Polarity Sets the polarity of the pulse to detect (positive pulse only, negative pulse only, or a positive or
negative pulse).
Time Limit Sets the time period condition to be met.
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.

Logic Trigger configuration menu
Use the Logic trigger to trigger the oscilloscope when the specified logic conditions occur. The logic conditions include the state of each
input, the condition to test (inputs go true, false, or are within a time limit), and the Boolean function of the inputs.
To open the Logic Trigger menu:
1. Double-tap the Trigger badge on the Settings bar.
2. Set the Trigger Type to Logic.

Field or control Description
Use Clock Edge? Enables or disables finding logic patterns that occur on the specified clock edge.
Logic Pattern Define Inputs Opens the Logic T
rigger - Define Inputs menu where you define the logic state (High, Low, or Don't
Care), and the signal threshold level that defines the logic state (high or low), for each analog or digital
signal. See Logic Trigger - Define Inputs configuration menu on page 217.
