Description
Source
Lists the source channel or waveform to use to trigger.
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.
Mode & Holdoff
Trigger Mode determines how the instrument behaves in the absence or presence of a trigger event.
Holdoff sets the amount of time the oscilloscope waits after a trigger event before detecting and
triggering on the next trigger event.
For additional information on Trigger Mode, Holdoff, forcing a trigger, and the Trigger Frequency
Counter see
on page 226.
Act On Trigger
Set the actions the instrument takes when a trigger event occurs.
For additional information on the Act On Trigger panel see
on page 227.
