The Anritsu MA24004A is a thermal power sensor engineered for precise average power measurement across microwave and millimeter-wave frequencies from 10 MHz to 40 GHz. Using true-RMS detection via Seebeck elements, it delivers accurate readings of any incident waveform regardless of signal type. The sensor spans a dynamic range of −30 dBm to +20 dBm with typical measurement accuracy of ±0.5 dB and linearity of 2.0% across its full frequency band.
