Test & Measuring Equipment

EE December 1987 TEST 8c MEASURING EQUIPMENT The field of electronic test and measuring equipment is large and still growing. Although not so long ago even an electronics engineer could get by with a multimeter, an oscillo- scope, and a signal generator, nowadays even a small laboratory or workshop is equipped with an array of general purpose instruments, such as multimeters and power meters, various signal generators, a frequency counter, distortion meter, wave or spectrum analyser, and one or two oscilloscopes. In many cases, this is complemented by an LCR meter, Q meter, waveform recorder, a storage oscilloscope, and others. To help readers find their way in this sometimes bewildering variety of equipment, we start this month a regular series of reviews of such equipment. Since the oscilloscope, after the multimeter, is probably the most frequently used instrument in an electronics environment, the series is started with a review of a number of dual-trace oscilloscopes. The aut...
