Edge Trigger

InfiniiVision Oscilloscopes User's Guide
The Edge trigger type identifies a trigger by looking for a specified edge (slope) and
voltage level on a waveform. You can define the trigger source and slope in this menu.
The slope can be set to rising edge or falling edge, and can be set to alternating edges or
either edge on all sources except Line. The trigger type, source, and level are displayed in
the upper-right corner of the display.
1 Press the [Edge] key in the Trigger section of the front panel to display the Edge
Trigger Menu.

2 Press the Slope softkey and select rising edge, falling edge, alternating edges, or
either edge. The selected slope is displayed in the upper-right corner of the display.
Alternating edge mode is useful when you want to trigger on both edges of a clock (for
example, DDR signals). Either edge mode is useful when you want to trigger on any
activity of a selected source. All modes operate up to the bandwidth of the oscilloscope
except Either edge mode, which has a limitation. Either edge mode will trigger on
Constant Wave signals up to 100 MHz, but can trigger on isolated pulses down to
1/(2*oscilloscope's bandwidth).
3 Select the trigger source.
