THE XYZs OF USING A SCOPE If you watch an electrical engineer tackling a tough design project, or a service engineer troubleshooting a stubborn problem, you’ll see them grab a scope, fit probes or cables, and start turning knobs and setting switches without ever seeming to glance at the front panel. To these experienced users, the oscilloscope is their most important tool but their minds are focused on solving the problem, not on using the scope. Making oscilloscope measurements is second nature to them. It can be for you too, but before you can duplicate the ease with which they use a scope, you will need to concentrate on learning about the scope itself: both how it works and how to make it work for you. The purpose of this primer is to help you learn enough about oscilloscopes and oscilloscope measurements that you will be able to use these measurement tools quickly, easily, and accurately. The text is divided into two parts: The first four chapters of Part I describe the functional parts of scopes and the controls associated with those parts. Then achapter on probes concludes the section. Part II allows you to build on the knowledge and experience you gained from Part I. The signals you’ll see on the screen of an oscilloscope are identified by waveshape and the terms for parts of waveforms are discussed. The next two chapters cover safety topics and instrument set-up procedures. Then Chapter 9 describes measurement techniques. Exercises there let you practice some basic measurements, and several examples of advanced techniques that can help you make more accurate and convenient measurements are also included. The last chapter in this primer discusses oscilloscope performance and its effects on your measurements. Having a scope in front of you while working through the chapters is the best way to both learn and practice applying your new knowledge. While the fundamentals will apply to almost any scope, the exercises and illustrations use two specific instruments: the Tektronix 2213 and 2215 Portable Oscilloscopes. The 2213 is a dual-channel, 60 MHz portable designed as an easy-to-use, lightweight, general-purpose oscilloscope. The 2215 is a dual time base oscilloscope with more features and capabilities; it’s included so you will understand dual time base scopes and appreciate the additional measurement capabilities they offer.

Information

The Digital Storage Oscilloscope This primer is about digital storage oscilloscopes: how they work; how you can make one work for you; and how to choose one that fits your needs. The concepts governing the operations of digital storage scopes are described in the first chapter. The subjects include analog-to-digital conversion, digital time bases, sampling, aliasing, and the features some digital storage scopes use to counter aliasing. The features of digital storage scopes are covered in the next chapter. General descriptions of how you might want to apply these features are also included there. CHOOSING A DIGITAL STORAGE SCOPE is the last chapter. It describes how you can determine whether a digital scope will perform well enough for your needs. The subjects include measurement parameters you can use to make this judgement: Useful Storage Bandwidth — which tells you the maximum frequency sine wave a digital scope can store; and Useful Rise Time — which describes how fast a pulse the instruments will store accurately. There is also a discussion of timing measurements in which you’ll find that a digital storage oscilloscope can make timing measurements much finer than its sample interval. After reading this chapter you will have the performance indicators you need to choose an instrument and to make comparisons between digital and analog storage scopes. The chapter, and this booklet, ends with a summary of the features you’ll want to consider when you finally pick your digital storage scope. Throughout the primer, digital storage scopes are compared to and contrasted with their closest cousins, the analog storage scopes, but some other storage instruments are neglected here. Chart recorders, scope cameras, waveform digitizers (or “transient recorders” as they are sometimes called), and oscillographs are all perfectly suited for their intended applications, but reviewing them here would have resulted in greater length than is practical in this primer.
