INTRODUCTIONDrDAQ virtual oscilloscope is a software section of the USB DrDAQ data logger. It enables one togenerate arbitrary waveform from the inputs section. The PICO technology PC enabled programs are easyand intuitive to use. The product offers superior viewing quality and they can be used for training andknowledge transfer sessions. The system has a data logger that captures data and displays it graphicallyon a PC using the virtual oscilloscope software. Electronic properties of materials are closely related tothe structure of the material on the atomic scale. The virtual oscilloscope is useful in displaying theelectrical signals on the PC and measure its value. There are various waveforms generated as output suchas,(i)Square waveform(ii)Triangle waveform(iii)Ramp or sawtooth waveform(iv)Pulse waveformSome of the main electrical parameters that are analyzed in this paper are the amplitude, period,frequency, peak values, rms value and the average values. There is a relationship among some of theparameters for instance the period and the frequency are inversely proportional. The waveformpropagates in cycles and the time taken to complete one full cycle is referred to as the period. Theoscilloscope samples the inputs in terms of 8 bits and provides for 256 possible voltage levels.AIMS AND OBECTIVES(i)To determine the measurement of electronic waveform parameters while testing on a piece ofelectronic equipment.(ii)To describe the operation of measurement techniques, instruments, and their connections withhardware and software.(iii)To use the virtual oscilloscope to analyze waveforms and discuss the values obtained in termsof ac and dc values as well as the relationship of the attributes of a waveform.PROCEDUREEquipment(i)DrDAQ data logger and oscilloscope(ii)BNC-T adapter(iii)Oscilloscope probes(iv)Signal generator(v)BNC to 2 leads(vi)Connectors and cables connecting function/signal generator to oscilloscopes and speaker.(vii)Task 1
(i)Connect a signal generator with a suitable square wave or pulse output to the input of thecircuit as shown below.(ii)Connect a virtual scope DrDAQ as shown below, with suitable software running on theattached laptop and carefully measure the step response of the following circuit:
Task 2(i)Describe the system used in task 1 above(ii)Obtain a copy of the manufactures data sheet and list the key parameters and limitations ofthe device.Some of the key features of the DrDAQ data logger and virtual oscilloscope are,
