Product Overview
HP 3852A Data Acquisition Mainframe – Used with Multiple Plug-ins
The Hewlett-Packard 3852A is a modular data acquisition and control unit designed for flexible measurement and automation tasks. This unit is equipped with a mix of HP plug-in modules, expanding its capabilities for a wide range of test applications.
In its time, the HP 3852A was a lab workhorse — managing sensors, relays, and automated routines with precision. Its modularity let engineers scale to complex experiments, and this system still reflects that design ethos. Its story continues as a versatile measurement hub, now ready for your bench.
Product Condition
Used. Shows cosmetic signs of handling from lab service. Unit powers on and modules seat securely. Passed self-test with the exception of Error 39 (memory loss), which is most likely related to the backup battery on the main board. The backup battery will need replacement for full functionality, which is like soldered onto the main board. No factory packaging is included.
Product Overview
HP’s 3852A system was part of the company’s trusted test and measurement line, designed for automated data logging and control. With multiple plug-in slots, it supported a wide mix of input, switching, and timing functions. This unit comes preconfigured with several plug-in cards, offering both analog and digital measurement flexibility.

Frequently Asked Questions
What modules are included with this HP 3852A?
This unit comes with four 44710A modules, one 44713B, two 44719A modules, and one 44701A module installed.
What does Error 39 mean?
Error 39 indicates a memory loss condition, typically due to the backup battery on the main board reaching end of life. Replacing the battery resolves this issue.
Is the system functional aside from Error 39?
Yes. The unit powers on, recognizes modules, and passes self-test except for the battery-related memory error.
What differentiates the HP 3852A from other DAQ systems?
Its modular design and wide choice of plug-ins made it adaptable to diverse test needs, from basic monitoring to complex automated routines.
Why is HP instrumentation valued today?
HP’s test equipment legacy is renowned for durability, precision, and design consistency — qualities that remain sought after in labs and collections.
This HP 3852A has already logged data and driven experiments in its past life. With its suite of plug-ins intact and only a backup battery refresh ahead, its next measurements — and their story — belong to you.
