Aeroflex IFR RD300 Weather Radar Test Set

The Aeroflex IFR RD300 Weather Radar Test Set is a precision simulator-tester engineered for testing, calibration, and fault diagnosis of airborne weather radar systems. It performs routine radar testing, pattern verification, gain checks, and system calibration via a single calibrated coaxial cable connection, eliminating extensive equipment reconfiguration.
