Abstract

A Personal Computer (PC) based wave form generator for laboratory applications has been thought and developed which is generating Sine, Square and Triangular waves in the range of 1 Hz to 20 MHz. The generation, recording and monitoring of wave forms, controlled through USB Data Acquisition system (DAS) connected to computer which is having 14-bit ADC, 10-bit DAC and 12-I/O lines. In the present work National Instrument’s USB DAS 6009, Maxim Company’s Max038 waveform generator are used for Hardware development. Higher level Graphical language such as ‘LabVIEW’ is used to develop the software. The experimental study reveals that the developed system is quite suitable to perform laboratory applications accurately. The results obtained from system are in agreement with results of standard instruments.
