Complements Your Existing Instrument

The Anritsu MA24105A Inline Peak Power Sensor is designed to take accurate average power measurements over
2 mW to 150 W, from 350 MHz to 4 GHz. The sensor employs 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,W-CDMA/HSPA+, WiMAX, and TD-SCDMA. The forward direction path also include a
4 MHz bandwidth channel that has peak and comparator/integrator circuits that add measurement functions such as peak
envelope power (PEP), crest factor, complimentary cumulative distribultion function (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.

Operation with Personal Computer (PC)

The power sensor can be used with a personal computer running Microsoft® Windows via USB. It comes with a
complimentary copy of the PowerXpert™ application (version 2.11 or greater) for data display, analysis, and sensor control.
The software provides a front panel display making the personal computer appear like a traditional power meter.
The application has abundant features like data logging, power versus time graph, 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 the MA24105A Inline Peak
Power Sensor. The MA24105A is currently compatible with
Site Master™ (S3xxE), Spectrum Master™ (MS271xE and
MS272xB), Cell Master™ (MT8212E), BTS Master™
(MT822xB), VNA Master™ (MS202xA/B and MS203xA)
and Economy Benchtop Spectrum Analyzers (MS271xB).
The power sensor easily connects to these instruments via a
USB A/Micro-B cable.
