Physics 3330 Experiment #1 Fall 1999 Electronic Instruments Purpose This experiment introduces the four basic electronic instruments you will use in the course: the oscilloscope, the function generator, the counter/timer and the digital multimeter. Spend enough time in the lab this week to get familiar with the instruments. You do not have to write a report on this experiment. Introduction Any time you develop a new circuit, repair an electronic instrument, or measure the performance of an electronic component or system, you will need to use one or more items of test equipment. Almost every task requires an oscilloscope, the basic instrument for visualizing the time dependence of electronic signals. A signal or function generator is used to produce periodic signals of the frequency, amplitude, and waveform needed for input to the device under test. The counter/timer can measure time intervals and frequencies very accurately, and the digital multimeter measures voltages, currents, resistance, and it can test silicon diodes and transistors. Everything you do in an electronics laboratory depends upon your familiarity with these instruments. The instructions for this experiment are designed help you start seeing patterns on the oscilloscope screen as soon as possible, and to familiarize you with the basic controls of each instrument. They do not cover all of the capabilities of the instruments. For greater detail, consult the manufacturer's manuals kept on the book shelf in the lab. Readings 1. D&H 6.1, 6.3-6.7. Skim 1.1-1.8 2. You also may look at Sections 1.01-1.12 of Horowitz and Hill as well as the first three appendices: The Oscilloscope, Math Review, and The 5% Resistor Color Code. Outline of the Experiment 1. Operation of the Tektronix 2246 oscilloscope, the FG504 function generator, the DC504A counter/timer, and the Fluke 77 digital multimeter. 2. Digital measurement of voltage, time, and frequency with the oscilloscope. 3. Set up test waveforms on the oscilloscope. Experiment #1 1.1 Fall 1999 Problems (You need not turn these in this week): 1. Learn the color code for resistors (See D&H section 1-7). The sequence of colors black brown red orange yellow green blue violet gray w hite can be remembered by memorizing the backpacker's lament: Black bears resting on your gear bring very gray w eather. What are the values and uncertainties of the resistors in Figure 1.1? Write the resistance using the most appropriate units of , k or M, and include the % tolerance. (For example, 1.8 k
