Preface
einyone who develops an interest in electronics as a hobby
;oon realises the importance of having a few items of test
equipment. Things can and do go wrong from time to time,
end electronics projects are very unforgiving if even the most
minor of errors are made. Trying to track down something as
;imple as ac racked printed circuit track can be very difficult
end time consuming without the aid of some test equipment.
There is a wide range of test equipment available these days,
ind much of this is at prices within the range of many elec-
tronics hobbyists. The main questions that face someone
;etting up an electronics workshop are what equipment is
relevant to their needs, what can the various items of test
equipment be used for, and how can they be used to good
effect in practice?
This book aims to answer these questions, and is primarily
concerned with oscilloscopes. Chapter 1d eals with the basics
pf oscilloscopes, including their basic function, their controls
end facilities, and advice on buying a suitable instrument.
Chapter 2 is concerned with using an oscilloscope to test
various types of circuit, including digital and linear types. The
third chapter deals with other items of equipment, including
logic probes, pulsers, signal generators, digital frequency
meters and component testing. The capabilities and limita-
tions of these units are discussed, together with some advice
on what to buy and how to set about using them for fault
finding. The obvious omission is the multimeter, but this all-
important piece of test equipment is covered in two other
books (BP239 and BP265), by the same author and publisher.

Warning
Never make tests on any mains powered equipment that is
plugged into the mains unless you are quite sure you know
exactly what you are doing.
Remember that capacitors can hold their charge for some
considerable time even when equipment has been switched off
and unplugged.
