"A lot of progress was made in 1949 and 1950. Work was well underway by [[Logan Belleville]], [[Dick Rhiger]] and [[Howard Vollum|Howard]] on the high speed scope, the 517. This used some brand new circuitry, [[distributed amplifier|distributed (or chain) amplifiers]], using 16 to 20 tubes in each stage to get the power needed to handle the high frequencies. Our best prediction at that time was that there were only about 30 to 50 people in the whole world who had need of a scope with 60 to 100 megacycle bandwidth. As it turned out, when we brought out a higher speed scope, people were able to design equipment of greater bandwidth and needed even faster measuring instruments. The cycle was regenerative. Having faster, more accurate measuring tools created a demand for even more measuring tools. We eventually sold several thousand of this instrument." | "A lot of progress was made in 1949 and 1950. | ||
