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