Nearly every item in this category is the same underlying Agilent test instrument you'll find elsewhere on this site — a multimeter, an attenuator, a frequency counter, a power module — except supplied here already calibrated, often with the calibration data and measurement uncertainties included as part of the order. That's a different buying decision to just needing a working instrument: it's for a lab or QA process that has to show traceable calibration on the paperwork, not only a functioning meter on the bench.
Stock here spans legacy Agilent 34401A digital multimeters, 8494A step attenuators, 53132A frequency counters, 34970A data acquisition switch units, and 66xxx-series DC power modules, most listed with CAL, CALD (calibrated with data) or CALDU (calibrated with data and uncertainties) variants. A handful of Ametek pieces round out the category. We are not Agilent, and not an authorised Agilent distributor — we source and supply genuine Agilent stock through the open market and established distribution channels, with datasheets and certificates of conformity available on request. Agilent's test-and-measurement business became Keysight Technologies in 2014, so this is legacy pre-2014 stock, not a current Agilent-branded catalogue.
If you need the same class of instrument without the calibration certification requirement, our broader Test & Measurement category and Agilent brand page cover the wider legacy range.
