Event Trigger (Alarm)
At the given example the Event has been started by the PPV of 5.278 mm/s at
33 Hz. The PPV value meets the condition of Reduction Factor that has been set to
0.5 as the value of 5.278 mm/s is at 50% of the L2 curve height at this point (the
L2 at 32.9 Hz is around 10.5 mm/s). The SVAN 958A stores the value that triggered
the Event as the Alarm value that can be displayed in SvanPC++:
