The HP Model 4342A Q Meter is designed to meet the requirements for making easy and accurate quality factor measurements in the laboratory, on the production line, or in QA incoming inspection areas. The direct reading, expanded scale of the 4342A permits measurement of Q from 5 to 1000 and the reading of very small changes in Q resulting from variation in test parameters. The long frequency dial scale and the pushbutton range selector continuously cover the frequency range of 22kHz to 70MHz (in seven - 1/3 decade steps) and permit setting the frequency to an accuracy of 1.5% with 1% resolution.
