465

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

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.

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