5If you select an edge term, one channel must be set to a rising edge or a falling edge. All other channel edges will be set to don’t care (X).

a Press the Channel softkey (or rotate the Entry knob on mixed-signal oscilloscopes) to select the channel.

As you select a channel, the channel is highlighted in the selected pattern list shown in the waveform area.

bThen press the X softkey to select rising edge or falling edge. All other channels will be defaulted to don’t care (X).

If you want to reassign an edge to a different channel, repeat the above step. The value of the original channel edge will be defaulted to X (don’t care).

Trigger on: is the next stage in the trigger sequence. When you select the Stage

Trigger on: softkey, the next softkey to the right will display Trigger: and give you

a list of the terms you can define for the Trigger on: stage. The Trigger on: stage can be set to one of the following conditions:

Pattern 2 Entered – A pattern is entered on the last edge that makes the pattern true (logical AND).

Pattern 2 Exited – A pattern is exited on the first edge that makes the pattern false (logical NAND).
