UNIVERSITY OF CALIFORNIA, DAVIS Department of Electrical and Computer Engineering EEC180A DIGITAL SYSTEMS I Winter 20 12 LAB 2: INTRODUCTION TO LAB INSTRUMENTS The purpose of this lab is to introduce the basic lab instruments - digital oscilloscope, power supply and function generator. You will build two very simple circuits and verify their operation. You should also read the Lab Instrument Reference Guide, best viewed on the web site since it contains color annotation, for an overview and basic operating procedures of the lab instruments you will be using. At the end of this lab, your TA will give you a timed , practical examination on the use of these instruments. Hardware Required: 1 pc. 74LS04 Hex Inverters 1 pc. 74LS163A Synchronous 4-bit Binary Counter Preparation Bring a few sheets of graph paper to the lab for making sketches of signals. Check the 74LS04 and 74LS163A datasheets on the course web site and record the device pin-outs. Read the general description of each part to get an idea of how it works if you don't already know. Determine all pin numbers for connecting circuits, particularly for the ring oscillator. Read this entire lab write-up. Note that each student will be doing the lab individually (i.e. - not with a partner or group) so it is important that you take responsibility for understanding what the lab requires. I. HP 54600B Oscilloscope 1. Turn on the oscilloscope and allow it to warm up for about a few minutes 2. Attach a cable or 10:1 scope probe to Ch. 1 of the scope. Connect the cable or scope probe to the front-panel probe adjust signal on the oscilloscope. Adjust the voltage and time scales as necessary to display the signal. You should see a 0-to-5 V square wave displayed on the screen. Measure the period of the signal based on the time scale and calculate the frequency of the signal. 3. Press the 1 button to display the configuration settings for Ch. 1 of the scope. Make sure the Probe attenuation factor matches the probe or cable that you are using. For a 10:1 probe, the attenuation factor setting should be 10; otherwise, it should be 1. An incorrect
