Chapter 1 — General Information
1-1 Scope of Manual
This manual provides general information, installation, and operating information for the Anritsu MA24104A
Inline High Power Sensor. Throughout this manual, the terms MA24104A, inline high power sensor, and
power sensor will be used interchangeably to refer to the device. Manual organization is shown in the table of
contents.
1-2 Introduction
This chapter contains general information about the MA24104A power sensor. It includes a general description
of the device and information on its identification number, information on initial inspection, and preparation
for storage and shipment.
1-3 Description
The MA24104A power sensor is a highly accurate, standalone instrument that communicates with a PC via
USB. The MA24104A also communicates with many Anritsu handheld instruments, such as Spectrum Master,
BTS Master, VNA Master, Cell Master, and Site Master (Option 19 required in these instruments). The power
measurement capability of MA24104A is intended to mimic that of a traditional thermal (thermo-electric)
power sensor. Therefore, it is ideal for measuring the average power of CW or modulated RF waveforms such
as 3G, 4G, OFDM, and multi-tone signals. In other words, it measures true RMS power regardless of the type
of input signal.
1-4 Initial Inspection
Inspect the shipping container for damage. If the shipping container is damaged, retain it until the contents of
the shipment have been checked against the packing list and the power sensor has been checked for
mechanical and electrical operation. The following items are included with every MA24104A shipment:
•MA24104A, inline high power sensor
•40-168-R, external power supply
•2000-1566-R, USB 2.0A to Mini-B cable
•800-441, RS232 cable
•69747, AA Alkaline batteries (qty 3)
•2300-525, CD containing required software and manuals
If the shipment is incomplete or if the power sensor is damaged mechanically or electrically, notify your local
sales representative or Anritsu Customer Service. If the shipping container is damaged or shows signs of
stress, notify the carrier as well as Anritsu. Keep the shipping materials for the carrier's inspection.
1-5 Identification Number
All Anritsu power sensors are assigned a unique seven digit serial number, such as “0701012”. The serial
number is printed on a label that is affixed to the unit. When ordering parts or corresponding with Anritsu
Customer Service, please use the correct serial number with reference to the specific instrument's model
number (for example, model MA24104A power sensor, serial number: 0701012).

Preparation for Storage/Shipment General Information
1-2 PN: 10585-00016, Rev. A MA24104A UG
Customer Asset Tag Placement
When affixing an asset tag to the MA24104A, please use the area indicated below to insure that the asset tag is
retained with the product during service.
1-6 Preparation for Storage/Shipment
Preparing the power sensor for storage consists of cleaning the unit, packing the inside with moisture-
absorbing desiccant crystals, and storing the unit in the recommended temperature environment. Please refer
to the data sheet for storage temperature recommendations.
To provide maximum protection against damage in transit, the power sensor should be repackaged in the
original shipping container. If this container is no longer available and the unit is being returned to Anritsu for
repair, please advise Anritsu Customer Service; they will send a new shipping container free of charge. In the
event neither of these two options is possible, instructions for packaging and shipment are given below:
• Use a Suitable Container: Obtain a corrugated cardboard carton. This carton should have inside
dimensions of no less than 15 cm larger than the unit dimensions to allow for cushioning.
• Protect the Instrument: Surround the unit with polyethylene sheeting to protect the finish.
• Cushion the Instrument: Cushion the instrument on all sides by tightly packing urethane foam
between the carton and the unit. Provide at least three inches of dunnage on all sides.
• Seal the Container: Seal the carton by using either shipping tape or an industrial stapler.
• Address the Container: If the instrument is being returned to Anritsu for service, mark the address of
the appropriate Anritsu service center and your return address on the carton in one or more prominent
locations.

Chapter 3 — Using the Power Sensor
3-1 Introduction
This chapter provides information on using the Anritsu Power Meter application with the MA24104A inline
high power sensor. It provides a description ofthe Graphical User Interface, various settings ofthe application,
basic procedures for Making Measurements, as well as information about Uncertainty of a Measurement.
3-2 Sensor Overview
The power sensor’s connectors are illustrated in the figure below:

Battery Compartment (supports 3AA size batteries)
Note: When using battery power with the RS232 interface, the MA24104A enables an auto shutdown
(sleep) feature. If the RS232 bus is disconnected or becomes inactive, the power sensor shuts down
(sleeps) to preserve battery power. The sensor automatically powers up (wakes up) when the host is
reconnected or becomes active. Zeroing is then required before taking measurements.
