DDG-210 is a Digital Delay Generator which can control experiments as a master device. Timing is referenced to the leading edge of the START pulse. There are 6 signal outputs available on which a sequence of up to 64 pulses can be defined. This sequence is called a cycle. The hardware allows to execute one to 65,535 cycles without interruption or
indefinite repetition of the cycle.The polarity of the start and signal outputs is selectable.
