HP 03582 Extender Card Set 03582-66531 -66532 -66533 3582A Spectrum Analyzer
The HP 03582 Extender Card Set is a three-board service accessory designed for use with the HP 3582A Spectrum Analyzer. Extender cards allow a technician to access the circuitry of a normally seated board while it remains electrically connected and operational within the instrument — making it possible to probe, measure, and troubleshoot live signals that would otherwise be inaccessible with the board fully seated in its card cage. This set includes all three extender boards plus a plastic-cased component kit.

Applications
Extender card sets like the HP 03582 are essential tools for bench-level service and repair of HP modular spectrum analyzers. The HP 3582A is a dual-channel FFT spectrum analyzer introduced by Hewlett-Packard in the late 1970s and widely used through the 1980s for low-frequency signal analysis (DC to 25 kHz), vibration analysis, audio testing, and electroacoustic measurement. Because the 3582A uses a card-cage architecture with plug-in circuit boards, extender cards are required to access live board signals during service — a technician seats the extender between the motherboard connector and the plug-in card, raising the card out of the cage so test probes can reach its components while the analyzer continues to run. These sets are rarely found new and are particularly valuable to engineers and technicians maintaining 3582A units still in service today in acoustic labs, vibration test facilities, and legacy signal-analysis setups.
This HP 03582 Extender Card Set for the HP 3582A Spectrum Analyzer is new old stock — unused and in original unissued condition. All three extender cards (03582-66531, 03582-66532, and 03582-66533) are present, each marked Rev A, made in the USA. The included plastic component case contains its foam-backed component kit: a 3000 pF ±5% disc capacitor, glass fuses, and a resistor, all appearing unused. The boards and components show only minor shelf storage wear consistent with long-term storage. Please view our photo set and contact us if you have any questions.
