What are the white edges on my MSO4000?
The MSO4000 has multiple transition detection hardware. When the system detects multiple transitions, the user will see a white edge on the display. White edges indicate that more information is available by zooming in or acquiring at faster sampling rates. In most cases zooming in will reveal the pulse that was not viewable at the previous settings. If the white edge is still present after zooming in as far as possible, this indicates that increasing your sample rate on the next acquisition will reveal higher frequency information than your previous settings could acquire.
