Anritsu announced new addition to Inline Power Sensor family –the MA24103A


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

Operation with PC

The power sensor can be used with a PC running Microsoft Windows via USB. It comes with PowerXpert application data display, analysis, and sensor control. The application has abundant features like data logging, power versus time graph, single sensor display, Real time settings update, and offset table that enable quick and accurate measurements.

Operation with Anritsu Handheld Instruments 

Handheld instruments having the high accuracy power meter software Option 19 can operate both Inline Peak Power Sensors. The power sensor easily connects to these instruments via a USB A/Micro-B cable. The MA2410xA sensors are currently compatible with most Anritsu handheld instruments. Refer to your instrument technical data sheet or contact your sales representative to ensure compatibility.
