Agilent/Keysight 85047A

The Agilent/Keysight 85047A is a two-port S-parameter test set that enables precise characterization of RF and microwave devices across an extended frequency range. This test accessory connects directly to compatible network analyzers and measures reflection and transmission characteristics bidirectionally with a single connection, eliminating the need for device reorientation. The 85047A delivers 15 dBm output power at the test port with insertion loss below 5 dB, making it suitable for accurate device tuning and component validation in production and development environments.
