Digital-Pattern Trigger

This type of trigger is useful when trying to capture noise, vibrations or some other physical disturbance

that occurs at a particular point in a digitally-sequenced process, such as a relay-logic-control system.

When “Digital Pattern” is selected as the Triggering Type, the 16-bit pattern extension appears (as

indicated in the following figure). The Condition box allows the following choices:

Equal To (=) / Not Equal To (< >) – These options treat each digital line as a separate input to be

compared to logical 1 or 0. Selecting “Equal To” triggers only on the exact pattern of 1’s and 0’s selected,

while “Not Equal” triggers on all others. You can also set any of the inputs to “don’t care” (X), which

excludes it from the comparison.

Greater Than (>) / Less Than (<) – These options interpret the digital inputs as a single 16-bit value and

allow a threshold trigger.
