Overview

The Anritsu MA247xD Series are standard diode power sensors for use with the ML2430, ML2480 and ML2490 series power meters. They are built for high-dynamic-range, high-accuracy CW and TDMA power measurements.

The sensors have a 90 dB dynamic range, from -70 dBm to +20 dBm, and linearity better than 1.8%. Their 4 µs rise time is fast enough for power measurements on GSM and similar TDMA systems that use GMSK modulation.

The series has four models. The MA2472D covers 10 MHz to 18 GHz and the MA2475D reaches 50 GHz. Each sensor stores its calibration factors in EEPROM and has a precision RF connector with a hexagon coupling nut, so it can be attached with an industry-standard torque wrench.
