The Keysight Technologies (formerly Agilent HP) V8486A is a high-performance V-band waveguide power sensor designed for precise average power measurements from 50 GHz to 75 GHz. Utilizing a sensitive diode power-sensing element, it provides a measurement range from -30 dBm to +20 dBm. It features an exceptionally low VSWR of 1.06 to minimize mismatch uncertainty, a 50 MHz calibration port, and calibration traceability to the US National Institute of Standards and Technology (NIST). It is highly compatible with Keysight/Agilent EPM, EPM-P, and P-series power meters, as well as several legacy meters.
