The Agilent 772D is a high-performance, dual-directional coupler designed for broadband swept measurements in the 2 to 18 GHz range. This coupler can be combined with Agilent power sensors and power meters for reflectometer applications. Forward and reverse power measurements on transmitters, components, or other broadband systems are made simpler using the Agilent 772D. The broadband design allows the use of a single test setup and calibration for tests spanning the entire 2 to 18 GHz range.
