History

Manuals – Specifications – Links – Pictures

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. The 475 is a 200 MHz sister model. See also 465M.

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

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

Internals

The 465 uses tunnel diodes with Tek part number 152-0125-00, which are equivalent to TD3A, and 155-0032-00 chips (their -01 grade) as trigger amplifiers.
