A Virtual Delay Generator Design and Its Application

A virtual delay generator was developed via software by considering the features of a real ‘gate and delay generator’. The signals supplied from a pulse generator were processed with a preamplifier, an amplifier and a timing single channel analyzer (SCA) and, the SCA output signals were transferred to the real ‘gate and delay generator’ (real instrument) and the virtual delay generator (virtual instrument; VI) simultaneously. They were compared with each other by changing amplitude, delay time and width values of the output signals from both instruments. It was found that the results from the virtual generator were highly in compatible with those of the real one. Obtained results showed that the developed virtual delay generator could be used as the real one.
