WaveAlert Key Points.
H You can use WaveAlert to monitor up to four waveform s or DPO
Math waveforms. Howeve r, adjacent waveforms can not touch or
overlap on the screen.
H To inc rea se your chances of capturing an a nomaly by acquiri ng
the maximum number of waveforms per second, set
ACQUIRE > Horizontal Resolution to Fast Trigge r
(500 points).
H When WaveAlert is on, the front-panel WAVEFORM INTENSI-
TY knob controls the persistance of t he anomalous waveform
instead of waveform intensity.
H To ca pture a very random eve nt (minutes to hours), enable the
Wfms to Disk on Anomaly function to write anomalous
waveform data to a disk file in .isf format. The number of files
you can save depends on the waveform record length. You can
determine when the anomaly occured by checking the file create
date and time.
H You can use WaveAlert on DPO math waveforms.
H Changing the vertical or horizontal oscilloscope settings does not
affect the sensitivity setting. The sensitivity is calculated from
the new waveform data after changing the oscilloscope settings.
