Overview
The Anritsu MA2400xA series thermal power sensors are designed for use with the ML2430, ML2480 and ML2490 series power meters. The series comprises three models that share the same –30 dBm to +20 dBm measurement range and differ in upper frequency limit and RF connector: the MA24002A covers 10 MHz to 18 GHz with an N(m) connector, the MA24004A covers 10 MHz to 40 GHz with a K(m) connector, and the MA24005A covers 10 MHz to 50 GHz with a V(m) connector.
Measurement principle
Thermal sensors use Seebeck elements. The combined effect of a thermal gradient and charge migration between dissimilar metals produces a true reading of the average power of any incident waveform, independent of modulation type or access scheme. This true-RMS detection gives accurate average power measurements over 50 dB of dynamic range.
Calibration and connectors
Each sensor stores its calibration factor and linearity correction data in a built-in EEPROM, so the power meter applies the corrections automatically. The sensors incorporate precision RF connectors with a hexagon coupling nut for attachment with an industry-standard torque wrench, which helps maintain consistent, repeatable connections and protects the connector from damage.
