Sensor Descriptions

MA244xD High Accuracy Diode Sensors 

Description 

The Anritsu MA244xD standard diode sensors are designed for 
use with the ML2430, ML2480 and ML2490 series power meters. 
They are designed for high dynamic range, high accuracy CW and 
TDMA measurements. With a built-in 3 dB attenuator, the 
MA244xD minimizes input SWR and is best used where the best 
measurement accuracy is required over a large dynamic range, as 
when measuring amplifiers. The MA244xD sensors have a 
dynamic range of 87 dB compared to the 90 dB dynamic range of 
MA247xD standard diode sensors. 

Features 

• Wide dynamic range sensors (-67 dBm to +20 dBm) 
• Accurate CW average power measurements 
• Wide frequency coverage from 10 MHz to 50 GHz (sensor 

dependent) 

• Calibration factors stored in EEPROM 

MA248xD Universal Sensors 

Description 

The MA248xD series are true RMS sensors with a dynamic range 
of 80 dB. These power sensors can be used for average power 
measurements on CW, multi-tone and modulated RF waveforms 
such as 3G, 4G, and OFDM. The sensor architecture consists of 
three pairs of diodes, each one configured to work in its square 
law region over the dynamic range of the sensor. Therefore, it 
measures true RMS power regardless of the type or bandwidth of 
the modulation of the input signal. Option 1 provides TDMA 
measurement capability, calibrating one of the diode pairs for 
linearity over a wide dynamic range, thus making it a truly 
universal sensor. 

Features 

• True-RMS detection enables accurate average power 

measurements of any signal type
