Experiments in Modern Physics Introductory Lab: PC-DAQ Rex Tayloe Department of Physics, Indiana University 1/1/03 Last Revised: 9/4/03 Goal Become familiar with operating and writing code to address the National Instruments DAQPad-6020E multifunction I/O device. Introduction In this lab you will get acquainted with the National Instruments [1] DAQPad-6020E multifunction I/O device (the "DAQPad") [2]. After this introduction, you will then be able to use this device to acquire data for other experiments. You will also be introduced to the Microsoft Visual C++ programming environment that is needed to program and readout the device. You will do these tasks: 1. Startup the DAQPad and test it with the provided test software. 2. Create and run a program with Visual C++ (starting with an example provided). 3. Run an existing program to acquire data, and then analyze this data to characterize a battery. 4. Write your own program to investigate a feature of the DAQPad. Equipment - Computer with NI-DAQ software ("MPL3") - DAQPad-6020E - voltmeter, (old) battery, variable resistance, misc. cables. - DAQPad manuals (Paper and/or on the computer) Preparation - Read the Section in Ref [3] about ADCs. - Read the introductory part of the the DAQPad manual[2], available as hardcopy near the computer, on the computer as a .pdf file, or at the National Instruments www site. - Create a voltage source by putting a (sufficiently large) resistance across the battery. You will use this to exercise the DAQPad.
