:''Note: The [[465M|Tektronix 465M scope]] has its own page.''
The '''Tektronix 465''' is a portable 100 MHz dual-trace oscilloscope with dual time-bases, [[introduced in 1972|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.
[[Bill Turner|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.


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.  The 465 uses tunnel diodes with Tek part number 152-0125-00, which are equivalent to [[TD3A]].  
From [[Media:Tekscope 1972 V4 N5 Sep 1972.pdf | Tekscope Vol. 4 No. 5, 1972 ]]:
<blockquote>
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.  


The 465 uses [[155-0032-00]] chips (their -01 grade) as trigger amplifiers.
Electrical design team assisting [[R. Michael Johnson]] in development of the 465 was: [[Frank Dewater]], [[Pete Janowitz]], [[Dave Laib]], [[Al Schamel]], and [[Bert tenKate]].  
</blockquote>


There was no 465A but a 465B (int. 1980) with the same base specs but improved performance.
[[Bill Turner]] worked as a calibration technician for the 465 oscilloscope group.


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