==== Digital pattern generator ====
{{Main article|Digital pattern generator}}
A logic signal generator or data pattern generator or [[digital pattern generator]] produces logic signals—that is, logical 1s and 0s in the form of conventional voltage levels. The usual voltage standards are [[LVTTL]] and [[LVCMOS]].
It is different from a "pulse/pattern generator", which refers to signal generators able to generate logic pulses with different analog characteristics (such as pulse rise/fall time, high level length, ...).

A digital pattern generator is used as stimulus source for digital integrated circuits and embedded systems - for functional validation and testing.
