HP 3852A Data Acquisition

The HP 3852A Data Acquisition series is a family of modular measurement and control products from Hewlett Packard. Built around the HP 3852A mainframe control unit, the system accepts plug-in modules for signal switching, measurement, digital input, and analog output, and can be expanded using the HP 3853A extender. These products are commonly used in automated test equipment, production testing, laboratory instrumentation, and industrial monitoring where multiple analog and digital signals must be acquired, processed, and controlled.

Products in This Series

• Mainframe and extender units — the HP 3852A control unit and HP 3853A extender that host plug-in modules.
• Multiplexer modules — high-speed FET multiplexers (44711A) and single-ended relay multiplexers (44706A) that route analog signals from many channels to a single measurement point.
• Measurement modules — the 44701A 5½ digit integrating voltmeter for precision voltage measurement.
• Digital input modules — the 44721A 16-channel totalize/interrupt module for pulse counting and event detection.
• Analog output modules — the 44727A 4-channel voltage/current DAC for generating control signals.
• Power supplies — the 3852PS and 3853PS units, with integrated analog and digital extenders, that power the mainframe and associated modules.

Many modules are offered in both component and terminal versions to suit different wiring and integration needs.
