Rising or Falling
option in the dropdown menu of the pulse direction: Dual edges
of a waveform can be triggered. This mode is especially useful for monitoring pulses
of both polarities at once.
Hysteresis
option: It is used to reduce false triggering on noisy signals. When
hysteresis is enabled, a second trigger threshold voltage is used in addition to the
main trigger threshold. The trigger fires only when the signal crosses the two
thresholds in the correct order. The first threshold arms the trigger, and the second
causes it to fire.

This trigger type helps to monitor when the signal enters or exits a specified voltage
window.
Three options are available for the pulse direction:
Entering, Exiting, Entering or
Exiting
. The
Threshold 1
and
Threshold 2
are the upper and lower voltage limits
of the window.
