This document is a quick reference guide for the Tektronix 2440 digital oscilloscope, first printed in 1987. Its core positioning is a "practical operation manual" - it does not replace the complete "2440 Operation Manual" (070-6695-00), but focuses on step-by-step operation and menu logic analysis of the instrument's core functions. The document structure is centered around the "front control panel buttons" and follows the process of "basic power on → functional modules → data output". It covers 19 key functional chapters, including 19 hardware schematics and menu screenshots, clarifying the hierarchical menu relationship, parameter adjustment range, and typical application scenarios of each button. It is suitable for engineers who have already understood the basic principles of oscilloscopes and need to quickly get started, especially focusing on practical guidance for characteristic functions such as dual trigger systems, multi-mode acquisition, GPIB communication, etc.
Abnormal measurement result: 1. waveform truncation; 2. Inappropriate adaptation of time base/sensitivity; 3. Measurement standard error: 1. Adjust VOLTS/DIV to avoid waveform truncation; 2. Adapt to time base/sensitivity; 3. Adjust the measurement level by pressing MEASURE → SETUP
GPIB communication failure: 1. Address/code mismatch; 2. Cable malfunction; 3. Equipment not ready. 1. Check GPIB parameters; 2. Replace the cable; 3. Confirm that the external device is in a ready state
