Overview

The Anritsu MA248xD series are true-RMS universal power sensors for average power measurements on CW, multi-tone and modulated RF waveforms, including 3G, 4G and OFDM signals. The series comprises the MA2481D and the MA2482D, which differ in frequency coverage.

Measurement principle

The sensor architecture uses three pairs of diodes, each configured to operate in its square-law region over part of the sensor's dynamic range. As a result, the sensor measures true RMS power regardless of the type or bandwidth of the modulation on the input signal.

Option 1

Option 1 (MA2480/01) adds a fast CW mode for high-speed measurements of CW signals, plus TDMA and pulse measurement capability. It calibrates one of the diode pairs for linearity over a wide dynamic range. Calibration factors are stored in the sensor's EEPROM.
