The MA2400xA series thermal sensors from Anritsu are designed to work seamlessly with the ML2430, ML2480, and ML2490 power meters. Using Seebeck elements, these sensors provide accurate average power measurements over a wide frequency range, from 10 MHz to 50 GHz, and a dynamic range of -30 dBm to +20 dBm. The use of a thermal gradient combined with charge migration between dissimilar metals ensures that the measurements are accurate for any RF signal, including those used in modern telecommunications.

Anritsu’s thermal sensors are known for their high SWR performance, low rise time, and sensor linearity, ensuring reliability in both laboratory and field environments. The built-in EEPROM stores essential calibration data, guaranteeing precise readings every time. Whether used for low-frequency or high-frequency applications, these sensors deliver consistent and trustworthy results.
