The Anritsu MA2400xA series are thermal power sensors engineered for precise average power measurements across RF and microwave frequencies. Built on Seebeck element technology, these sensors deliver true-RMS detection for any incident waveform by measuring thermal gradients and charge migration between dissimilar metals. Each sensor stores calibration factors and linearity correction data in onboard EEPROM, enabling automatic interpolation and correction by compatible power meters.
