Anritsu MA2468A Fast Diode Sensor, 10MHz to 6GHz

The Anritsu MA2468A is a fast diode sensor for RF power measurement spanning 10 MHz to 6 GHz. It delivers precise characterization of CW, average, and peak power across dynamic ranges exceeding 80 dB, making it ideal for production test and research applications requiring high-speed signal analysis. The sensor's sub-microsecond rise time and better-than-1.8% linearity enable accurate measurement of radar and communication signals including WiMax, WCDMA, WLAN, and GSM.

Internal EEPROM calibration data stored as a function of frequency, power, and temperature supports automatic interpolation and correction when paired with compatible Anritsu power meters.
