Tektronix 2445 2465 070-4631-00 Option 06 09 Counter Timer Oscilloscope Manual

This is the original Tektronix Instruction Manual (publication number 070-4631-00) for the 2445 and 2465 oscilloscopes equipped with Option 06 (Counter/Timer/Trigger) and Option 09 (Word Recognizer). It is the operators-level reference that covers setup, front-panel controls, operating procedures, and GPIB remote programming for both option features. The manual is printed and spiral-bound in Tektronix's standard blue cover format and dates from a first printing of August 1985, revised October 1986.

Applications

The Tektronix 2445 and 2465 are portable analog oscilloscopes from the mid-1980s that represented some of the most capable bench instruments of their era. The 2445 offered 150 MHz bandwidth and the 2465 offered 300 MHz, both in a compact, lightweight package aimed at field service engineers and lab technicians. Option 06 added a built-in Counter/Timer/Trigger capability — allowing precision time-interval measurements, frequency counting, and advanced delay-by-events triggering directly from the oscilloscope front panel, without a separate counter instrument. Option 09 added a 17-bit Word Recognizer, enabling the oscilloscope to trigger on a specific parallel data word, which was particularly useful for digital circuit debugging and microprocessor-based system development. This operators manual covers both options together and is the reference technicians and engineers need to configure, operate, and remotely control those features via GPIB. It remains a sought-after reference for anyone maintaining, calibrating, or operating a 2445 or 2465 with either option installed.
