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 as 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.

The delay line was offered as a “delete” option on early scopes, with the version without the delay line selling for $50 less. Apparently most customers ordered the delay line versions, and the 315 was the last scope introduced with the D suffix. | The delay line was offered as a “delete” option on early scopes, with the version without the delay line selling for $50 less.

Even so, the [http://bitsavers.org/pdf/tektronix/catalog/Tektronix_Catalog_1953-03.pdf 1953 catalog] which was the first the 315-D appeared in did not list the version without the delay line. It is quite possible that no plain 315 models were ever sold. | Even so, the [http://bitsavers.org/pdf/tektronix/catalog/Tektronix_Catalog_1953-03.pdf 1953 catalog], which was the first the 315-D appeared in, did not list the version without the delay line.
