Description
Overview
The Tektronix DA 4084 is a programmable distortion analyzer providing completely automatic operation for measuring harmonic distortion and signal analysis. Designed to military specifications, the instrument automates level setting, tuning, nulling of the fundamental, and display ranging to minimize testing time and human error while delivering accurate, repeatable measurements. The system includes a dedicated power supply and supports IEEE-488 (GPIB) programmable control for integration into automated test systems.
Key Features
- Frequency range from 10 Hz to 100 kHz with 10-step input range (200 μV to 200 V)
- Auto-ranging distortion measurement in modes: 100%, 20%, 2%, 0.2%, and dB
- 3.5-digit LED display with 2000-count resolution and analog-style bar graph
- Four built-in frequency weighting filters with user-selectable filter option
- Automatic level and dB ratio measurements
- IEEE-488 interface for ATE system integration
- Rugged military-spec construction with integrated power source
Applications
- Automated harmonic distortion measurement and analysis
- Signal quality assessment in manufacturing test
- Frequency-weighted audio and audio frequency measurements
- Automated test equipment (ATE) integration for batch testing
