Manuals – Specifications – Links – Pictures

The Tektronix 2465 is a four-channel 300 MHz portable oscilloscope. The 2445 is a 150 MHz version.

CRT is the 154-0850-01.

The 2465 is from the penultimate generation of analog Tektronix scopes.

The horizontal amplifier in the 2465 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 word recognizer probe.
• Option 10 added a GPIB interface for remote control.
