Define logic 6. Select the Boolean logic function for the combination of
the input channels. The oscilloscope will trigger on a

when the oscilloscope should trigger. Select True to
trigger the oscilloscope when the logic patterns go true.

the chosen pattern function (for exampl e, from AND to
NAND or NOR to OR).
