Applications

The HP 7758A and 7418A are eight-channel thermal-tip (heated stylus) strip chart recorders that produce traces on heat-sensitive Permapaper. They were designed to work with HP's 8800-Series Preamplifiers and could be integrated with a range of signal sources including scopes, tape recorders, computer terminals, and control units. The recorders were available in several configurations: mounted in a mobile cart, as a benchtop enclosure, in an upright cabinet, or as a rack-mount unit. These instruments date from the 1970s–1980s era of HP analog data recording and were used in laboratory, research, and instrumentation environments where multi-channel analog data capture on paper was required. This manual is the essential reference for anyone operating, troubleshooting, or performing maintenance on either model — covering everything from signal connections and system operation through gearbox adjustment, stylus calibration, and circuit-level service procedures.
