Agilent Technologies 87512A Transmission Reflection Test Kit

Agilent Technologies 87512A Transmission/Reflection Test Kit is a 50-ohm DC-to-2-GHz test set that measures the reflection and transmission characteristics of 50 Ω devices when used with a compatible Agilent/Keysight network analyzer. The kit uses type-N connectors and is specified for DC through 2 GHz operation, making it suitable for evaluating RF components, cables, and other 50 Ω devices in laboratory and service environments. The product is listed as obsolete in current vendor literature, reflecting its retirement from active catalogs, though historical documentation confirms its intended use as a dedicated accessory for transmission/reflection testing within the Agilent/Keysight instrumentation ecosystem.
