The Agilent/Keysight 8954A is a transceiver test interface that routes signals between measurement instruments and devices under test. It employs microwave switching technology to manage RF paths, audio circuits, and control lines, enabling comprehensive transmitter and receiver characterization across multiple signal domains. The unit integrates up to two RF signal sources, two RF monitors, one audio source, and one audio analyzer. Sixteen programmable Form A relays provide external device control and power supply routing to transceiver control connectors.
