The '''Tektronix 2465A''' is a four-channel 350 MHz portable oscilloscope. The '''2445A''' and '''2455A''' are 150 and 250 MHz versions. CRT is the [[154-0850-01]]. | |||
The '''[[2467]]''' and '''[[2467B]]''' are the same as the 2465A, except that the 2465A uses a conventional CRT while the 2467 and 2467B use a [[micro-channel plate CRT]] that enables bright traces at fast sweep rates, particularly with one-shot or low repetition rate signals. | |||
The 2465A is from the penultimate generation of analog Tektronix scopes. | |||
The horizontal amplifier in the 2465A was designed by [[Art Metz]] and [[Ken Schlotzhauer]]. Art Metz also worked on the triggers. Art Metz and [[Walt Ainsworth]] designed the sweeps. | |||
'''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. | |||
* 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. | |||
* Option 11 added two [[LEMO S-series connector|probe-power connectors]] on the rear panel of the instrument. Only shown in the 1987 catalogue. | |||
