The Tektronix 465 is a portable 100 MHz dual-trace oscilloscope with dual time-bases. The 465 was very popular and Tek made them for quite a few years. It is all solid-state except for the CRT. It was introduced in November 1972.

There was no 465A but a 465B (int. 1980) with the same base specs but improved performance. Bill W6WRT Turner said, "there never was an "A" version. Engineering started on it but decided to do a major revamp and went directly to the "B"."

The optional DM44 multimeter attaches to the top of the instrument.

Internals
