ANRITSU: Inline Power Sensor MA2410xA

The Anritsu MA2410xA Inline Peak Power Sensors are designed to take accurate average power measurements over 2mW to 150 W, from 25 MHz to 4 GHz. The sensors employ a "dual path" architecture that enables True-RMS measurements over the entire frequency and dynamic range allowing users to measure CW, multi-tone and digitally modulated signals such as GSM/EDGE, CDMA/EV-DO, WCDMA/HSDPA, WiMAX, and TD-SCDMA. The forward direction path also includes a 4 MHz bandwidth channel that has peak and comparator/integrator circuits that add measurement functions such as PEP power, crest factor, CCDF, and burst average power. Another detection circuit on the reverse direction adds reverse power measurement capabilities including reverse power, reflection coefficient, return-loss, and SWR. The presence of a micro-controller along with signal conditioning circuitry, ADC, and power supply in the sensor makes it a complete miniature power meter.

Anritsu has two variants of Inline Sensors

MA24103A - with frequency range from 25 MHz to 1 GHz
MA24105A - with frequency range from 350 MHz to 4 GHz
