Note: The Tektronix 465M scope has its own page.

The Tektronix 465 is a portable 100 MHz dual-trace oscilloscope with dual time-bases, introduced in November 1972. It is all solid-state except for the CRT. The 465 was very popular and Tek made them for quite a few years. According to microfiche records, 37 variations of the 465 were produced.

There was no 465A but a 465B (int. 1980) with the same base specs but improved performance. The 475 is a 200 MHz sister model. See also 465M.

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

From Tekscope Vol. 4 No. 5, 1972 :

Initial product planning and project coordination was provided by Leon Orchard. The mechanical design team for the 465 and 475, headed by Bob Rossman, was: Neal Broadbent, Bob Leith, Len McCracken, Bob Smesrud, Ilmars Smiltins, and Bob Twigg. Ken Holland and Bill Mark provided the attenuator design while Bob Johnson designed the P6065 and P6075 probes. Low-voltage power supply for the 465/475 was by George Ermini, and Dennis Braatz designed the high-voltage supply. Connie Wilson and Gary Nelson did the CRT development.

Electrical design team assisting R. Michael Johnson in development of the 465 was: Frank Dewater, Pete Janowitz, Dave Laib, Al Schamel, and Bert tenKate.

Bill Turner worked as a calibration technician for the 465 oscilloscope group.
