The move to use a 3” CRT rather than a 5” was to produce a “portable” oscilloscope, which the 315-D was promoted as. With dimensions considerably smaller than the 5” models and only weighing a modest 36 pounds, it offers a lot of performance in a small package. In [[introduced_in_1956|1956]], Tek introduced a rack mount version, the 315R. One has to wonder what the benefit of a 3" screen is when it was packaged is a rack sized instrument. | The move to use a 3” CRT rather than a 5” was to produce a “portable” oscilloscope, which the 315-D was promoted as.
