Anritsu MA2482D Universal Sensor, 10MHz to 18GHz

The Anritsu MA2482D is a true RMS power sensor engineered for broadband RF measurement across 10 MHz to 18 GHz. Its triple-diode architecture operates in the square-law region to deliver accurate average power readings of CW, multi-tone, and modulated waveforms - including 3G, 4G, and OFDM signals - independent of bandwidth. The 80 dB dynamic range spans six measurement ranges for versatile laboratory and production applications.

Key Features

• True RMS detection across signal bandwidth for reliable readings on any waveform type


• Option 1 enables TDMA measurement capability and calibrates a diode pair for enhanced linearity across the full dynamic range


• Internal EEPROM stores frequency-, power-, and temperature-dependent calibration data for automatic meter configuration


• Precision N-Type connector rated for standard torque wrench attachment

Typical Applications Broadband power measurement of modulated RF signals in wireless communications testing, including 3G/4G protocols and OFDM waveforms. Suitable for CW and multi-tone signal characterization across X-band and lower microwave frequencies.

Compatibility & Integration Connects directly to Anritsu ML24xxA/B, ML2480A/B, and ML2490A power meters. Requires ML2407A/08A and ML2437A/38A meter firmware revision 3.10 or higher. Integrates with PowerSuite software on Windows 95 or higher via GPIB or RS232 for trace viewing and data logging.
