Complements Your Existing Instrument

The Anritsu MA24104A Inline High Power Sensor is designed to take
accurate average power measurements from 600 MHz to 4 GHz and power
levels from 2 mW to 150 W. 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,WCDMA/
HSDPA, WiMAX, and TD-SCDMA. 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 PC

The power sensor can be used with a PC running Microsoft® Windows
via USB. It comes with PowerXpert™ application (version 2.0 or greater)
for data display, analysis, and sensor control. The software provides a
front panel display making the PC 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 MA24104A Inline High Power Sensor.
The MA24104A 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/mini-B cable. An
additional benefit of using the USB connection is that a separate DC
supply (or battery) is not needed since the necessary power is supplied by
the instrument.

In contrast, instruments with an RS-232 serial interface require an external
DC supply or three AA batteries in addition to the RS-232 serial cable.
These RS-232 instruments include the Site Master™ (S3xxD), Cell Master™
(MT8212B and MS2711D) and LMR Master™ (S412D) products. Mea­surements outside of the laboratory, such as during cellular base station
installation, maintnence, and repair are easy when battery power is used.
