The Anritsu MA2481B Universal Power Sensor delivers true RMS power measurements across 10 MHz to 6 GHz, supporting CW, multi-tone, and complex modulated waveforms including 3G, 4G, and OFDM signals. Built around three cascaded diode pairs operating in the square law region, it captures accurate average power from -60 dBm to +20 dBm with 3% linearity across its full frequency and dynamic range. The sensor integrates internal EEPROM calibration storage indexed by frequency, power, and temperature, enabling automatic correction through compatible Anritsu power meters.
