Abstract
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.
Highlights
Virtual instrumentation is an interdisciplinary field that merges hardware and software technologies in order to create flexible instruments for control and monitoring applications [1]
LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a graphical programming environment which has become prevalent throughout research labs, academia and industry [2]

Summary
Virtual instrumentation is an interdisciplinary field that merges hardware and software technologies in order to create flexible instruments for control and monitoring applications [1]. Contrary to the real instrument, virtual instrument (VI) is developed in a computer environment through the software. It has a lot of advantages according to the real one. LabVIEW can command plug-in data acquisition (DAQ) devices to acquire or generate analog and digital signals. It facilitates data transfer over General Purpose Interface Bus (GPIB) or Universal Serial Bus (USB), Ethernet or serial port [3]. Like the user interface of a real instrument, this panel is used to display control buttons and indicators [4]
