analog or digital channels is found.

Trigger > Setup... from the main menu.
2 In the Trigger Type drop-down list, select OR.
3 Use the Set All buttons to set the edges for all channels to (Rising),

4 To set the edges for individual channels, select the channel; then, select one of
the Set Selected Channel buttons: (Rising), (Falling), (Either), or X (Don't
Care).
