Trigger if.. State

Behavior. Use the Logic State trigger to trigger the instrument when all of the logic inputs to the selected logic function cause the

function to be True or False when the clock input changes state.

Channels 1, 2, and 3 represent the data inputs, and channel 4 represents the clock input. (The clock input is channel 2 on 2-

channel models.) You can set each data channel to be logic high, logic low, or a "don't care" value. You can set the channel

4 input to a rising or falling clock edge (or channel 2 on 2-channel models). Use the multipurpose knobs to change the

threshold voltages for logic levels other than TTL.

The Pattern Type buttons set the Boolean logic function for the trigger.
