The Keysight 3458A Multimeter is a high-performance 8.5-digit system multimeter engineered to deliver both high speed and high accuracy in a single instrument. Originally introduced under the Hewlett-Packard banner and carried forward through Agilent into the current Keysight lineup, the 3458A has long served as a reference-class bench and system DMM for production test, R&D, and calibration laboratory environments. The datasheet positions it as a multimeter that shatters performance barriers of speed and accuracy, combining seven measurement functions with digitizing capability in one chassis.
Per the datasheet, the 3458A is applied to test system throughput acceleration, calibration laboratory precision work, and high-resolution waveform digitizing. The instrument is positioned for production test floors where measurement speed and tight test margins drive yield, for calibration labs where 0.1 ppm transfer accuracy and low internal noise are required, and for engineering benches that need digitizing of repetitive or single-shot waveforms alongside conventional DMM measurements. Typical work described includes transfer measurements against intrinsic standards, automated characterization sweeps under GPIB control, and stand-alone measurement sequences executed from non-volatile program memory.
ValueTronics International has been a trusted source for new and pre-owned test and measurement equipment since 1992. Every instrument in our inventory is stored and processed in our 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, where our in-house technicians perform the receiving, inspection, and functional verification work that distinguishes a professionally graded instrument from an unverified marketplace listing. When you order a 3458A from ValueTronics, you are working with a vendor that has the instrument in physical inventory, has tested it, and stands behind it — not a drop-shipper or pass-through broker.
The 3458A originated as a Hewlett-Packard product. In 1999, HP spun out its test and measurement business as Agilent Technologies, and in 2014 Agilent transferred its electronic measurement division to Keysight Technologies. Instruments built under the HP and Agilent labels share the same 3458A model designation and full support continuity through Keysight today.
