Field or control
Description
Trigger When
(Use Clock Edge = No)
Defines the waveform condition on which to trigger.
• Goes True: All conditions change to a true state.
• Goes False: All conditions change to a false state.
• Is True > Limit: Condition remains true longer than a specified time.
• Is True < Limit: Condition remains true for less than a specified time.
• Is True = Limit: Condition remains true for a specified time (within ± 5%).
• Is True ≠ Limit: Condition does not remain true for a specified time (within ± 5%).
Clock Source
(Use Clock Edge = Yes)
Sets the signal to use as the clock. The clock signal can be a digital or analog waveform
Clock Edge
(Use Clock Edge = Yes)
Sets the signal transition edge (rising, falling, or either) for evaluating the logic condition at the clock
transition.
Clock Threshold
(Use Clock Edge = Yes)
Sets the threshold level that the clock signal must pass through to be considered a valid transition. The
clock threshold value is independent of the input signal threshold(s).
Define Logic
Sets the logic condition that must occur with all inputs.
• AND: All conditions are true.
• OR: Any condition is true.
• NAND: One or more conditions are true.
• NOR: No conditions are true.
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.
