– Compatibility & Integration
The 85025C is engineered specifically for the Agilent/Keysight 8757 series scalar network analyzers, with firmware revision 2.0 or greater recommended for the HP 8757A model. The adapter’s waveguide input accepts standard detector types, providing direct connection to the analyzer’s measurement channel. This architecture eliminates the need for external interface components in typical waveguide power measurement configurations.
