WaveAlert Wave
form Anomaly Detection. WaveAlert provides a way to detect
when a waveform deviates from a steady-state condition. WaveAlert monitors
the current waveform acquisition and compares it to the previous DPO waveform
acquisitions, using a sensitivity value to adjust the comparison tolerance. If the
current acquisition exceeds the comparison tolerance, the oscilloscope considers
the current acquisition a s an anomaly.
Anomaly
The osc
illoscope can respond to an anomalous waveform by stopping acquisitions,
emitting a beep, saving the anomalous waveform to a USB flash drive file,
printing the screen image to a hard copy device, or any combination of the above.
You can also select to highlight just the anomalous data in a waveform, or the
entire anomalous waveform.
To us e WaveAlert, follow these steps:
1. Display the waveform or waveforms on the screen.
2. Push the Acquire Menu front-panel button.
3. Pus
htheWaveAlert bottom button.
4. Push the Wfm Anomaly Detection side button to select On.
5. Push -more-1of2andthentheHighlight Anomalies side button to select
On.
6. Push -more-2of2andthentheSensitivity side button.
7. Use the general purpose knob t o set the comparison sensitivity value. As
signal noise and intensity levels affect the displayed waveform, you will
need to experiment with the sensitivity setting to reduce the number of false
anomalies due to signal noise.
8. Use the Waveform Intensity front-panel button to adjust the persiste nce
of the anomaly waveform.
