MA244xD Series : High Accuracy Diodes Sensors (CW)

View more

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 their built in 3 dB attenuator, the MA244XD minimize input VSWR and are best used where the best measurement accuracy is required over a large dynamic range, for example when measuring amplifiers. These sensors have a dynamic range of 87 dB compared to the 90 dB of MA247XD standard diode sensors. In all other respects the performance of the sensors is identical to the standard diode sensor.
