SquareWave models a simple square wave generator. It takes four parameters, used to specify the time the first pulse should begin, the pulse height and length, and the interval between pulses. It has four outputs, of four different types, so that it can be used to drive systems expecting different types of inputs. Often SquareWave is used to turn on various devices, such as sensors and laser sources, each at a precisely specified moment, to ensure that they are synchronized correctly
