The '''Tektronix 2465''' is a four-channel 300 MHz portable oscilloscope.   The
The '''Tektronix 2465''' is a four-channel 300 MHz portable oscilloscope from the penultimate generation of analog Tektronix scopes. The '''2445''' is a 150 MHz version.  ''See [[2465A]] and [[2465B]] for the successor versions.''
2465A is a 350 MHz scope and the 2465B is the 400 MHz version.  


It is the same as the [[2467]], except that the 2465 uses a conventional CRT
[[Wink Gross]] was the vertical system engineer for the 2465.  He designed the [[2465]] main vertical amplifier, the channel switch, and the auxiliary input preamp. 
while the 2467 uses a micro-channel plate CRT.   
[[Marv LaVoie]] designed the 2465 attenuator. 
The horizontal amplifier in the 2465 was designed by [[Art Metz]] and [[Ken Schlotzhauer]] ([[155-0239-00|trigger IC]]). Art Metz also worked on the triggers. He and [[Walt Ainsworth]] designed the sweeps.
[[Mike Metcalf]] designed the 2465 [[155-0242-00|Z axis IC]], both under the direction of [[Art Metz]].   
Art had horizontal system responsibility and designed the non-IC part of the horizontal as well.


The 2465 scopes are the last generation of analog scopes from Tektronix.
'''Options'''
* Option 01 (DMM) added a 4½-digit, fully autoranging digital multimeter which measures DC and AC voltage and current, resistance, dBV, dBm, continuity, and temperature.
* Option 05 (TV) added TV (back-porch) clamp circuitry to the Channel 2 input and TV trigger coupling modes, allowing selection of either horizontal or vertical sync pulses to obtain horizontal-line-sync or field-sync pulse triggering. A knob and an on-screen numerical display allows selection of a line number to be displayed. If the scope is in mixed time base mode, an intensified region is shown in the field rate display.
* Option 06 (Counter/Timer/Trigger) allows precision time-interval measurement, event and frequency counting, delay-by-events triggering, and logic triggering.
* Option 09 added option 06, the CTT, plus a 17-bit [[P6407|P6407 word recognizer probe]].
* Option 10 added a [[GPIB interface]] for remote control.
