The Anritsu MA2472D is a standard diode sensor engineered for precision power measurement across microwave frequencies. It delivers high dynamic range and exceptional accuracy for continuous wave (CW) and time division multiple access (TDMA) signals, making it ideal for GSM and GMSK-modulated systems. The sensor integrates with Anritsu ML2430, ML2480, and ML2490 series power meters through automatic calibration data retrieval, eliminating manual setup and enabling frequency-, power-, and temperature-compensated measurements.
