Figure 5-1. An analyzer operation during the capture of an overspeed event.
Summary
The trigger activated when ABS ACT SPD exceeded 1,050 FPM. The first 4,000 samples of
data collected represent the 11.111 seconds of ABS ACT SPD before ABS ACT SPD exceeded
1,050. The remaining 4000 samples collected represent the 11.111 seconds of ABS ACT SPD
after ABS ACT SPD crossed through the trigger level of 1050 FPM. The signal analyzer data
may be viewed using the keypad display or uploaded to ADDAPT for viewing.
Note that in the above example, if the trigger event occurred within the first 11.111 seconds
after the signal analyzer channel was enabled, the preview time would be reduced to the actual
amount of time that had elapsed between the enable of the signal analyzer channel and
occurrence of the trigger. The signal analyzer would still collect the full 11.111 seconds of data
that occurred after the trigger event.
