in the diagrams in this manual.
This indicates a prohibited operation. The prohibited operation is
indicated symbolically in or near the barred circle.
This indicates a compulsory safety precaution. The required operation
is indicated symbolically in or near the circle.
This indicates a warning or caution. The contents are indicated
symbolically in or near the triangle.

MA24xxA/B/D, MA2400xA OM PN: 10585-00004 Rev. T Safety-3
For Safety
Warning Always refer to the operation manual when working
near locations at which the alert mark, shown on the
left, is attached. If the operation, etc., is performed
without heeding the advice in the operation manual,
there is a risk of personal injury. In addition, the
equipment performance may be reduced. Moreover,
this alert mark is sometimes used with other marks
and descriptions indicating other dangers.
Warning When supplying power to this equipment, connect
the accessory 3-pin power cord to a 3-pin grounded
power outlet. If a grounded 3-pin outlet is not
available, use a conversion adapter and ground the
green wire, or connect the frame ground on the rear
panel of the equipment to ground. If power is
supplied without grounding the equipment, there is a
risk of receiving a severe or fatal electric shock.
Warning
This equipment can not be repaired by the operator.
Do not attempt to remove the equipment covers or
to disassemble internal components. Only qualified
service technicians with a knowledge of electrical
fire and shock hazards should service this
equipment. There are high-voltage parts in this
equipment presenting a risk of severe injury or fatal
electric shock to untrained personnel. In addition,
there is a risk of damage to precision components.

Safety-4 PN: 10585-00004 Rev. T MA24xxA/B/D, MA2400xA OM
Caution
Electrostatic Discharge (ESD) can damage the
highly sensitive circuits in the instrument. ESD is
most likely to occur as test devices are being
connected to, or disconnected from, the
instrument’s front and rear panel ports and
connectors. You can protect the instrument and test
devices by wearing a static-discharge wristband.
Alternatively, you can ground yourself to discharge
any static charge by touching the outer chassis of
the grounded instrument before touching the
instrument’s front and rear panel ports and
connectors. Avoid touching the test port center
conductors unless you are properly grounded and
have eliminated the possibility of static discharge.
Repair of damage that is found to be caused by
electrostatic discharge is not covered under
warranty.

Chapter 1 — General Information
1-1 Introduction
This manual provides descriptions and specifications for Anritsu Power
Sensors that are used in conjunction with Anritsu power meters. It
includes care, handling and performance verification information.
Anritsu offers the world's most comprehensive range of power meters:
•The ML2490 series has the performance required for narrow fast
rising-edge pulse power measurements (e.g., radar).
•The ML2480 series is suited for wideband power measurements
on signals such as W-CDMA, WLAN, and WiMAX.
•The ML2430 series is designed for CW applications, offering a
combination of accuracy, speed and flexibility in a low cost
package.
With various families of Power Sensors to choose from, you can trust
you'll find the right combination for precision power measurement.
Anritsu Power Sensors include:
•MA247xD Series Standard Diode Power Sensors
•MA244xD Series High Accuracy Power Sensors
•MA248xD Series Universal Power Sensors
•MA249xA Series Wideband Power Sensors
•MA2411B Pulse Power Sensor.
•MA2400xA Thermal Sensors
All Anritsu power sensors contain an internal EEPROM for storage of
calibration data as a function of frequency, power, and temperature.
This allows the power meter to interpolate and correct readings
automatically.
Note
Anritsu ML2407A/08A and ML2437A/38A Power Meters
must have meter firmware revision 3.10 or higher when
used with Anritsu MA24xxD and MA2400xA Series power
sensors.
Note USB sensors are not covered in this manual.

1-3 Documentation Conventions
The following conventions are used throughout this document:
Instrument Identification
Throughout this manual, the terms MA24xxA/B/D and MA2400xA,
Power Sensor, or DUT (device under test) are used to refer to the power
sensor. When required to identify a specific model, the specific model
number is used, such as MA2496A. Manual organization is shown in the
table of contents.
Hard Keys or Front Panel Keys
When testing sensors, the power meter and test equipment front panel
hard keys are denoted with a bold Sans Serif font such as “Press the
front panel Frequency key.”
User Interface, Menus, and Soft Buttons
The power meter user interface consists of menus, button lists,
sub-menus, toolbars, and dialogboxes. All of these elements are denoted
with a special font, such as the Calibration menu or the AutoCal button.
User Interface Navigation Conventions
Navigation in Power Meter and Test Equipment
Elements in navigation shortcuts or paths (identified as
“Navigation”) are separated with the pipe symbol (“|”). Menu and
dialog box names are distinctive Sans Serif font. Button names
are in Title Case. For example, you would enter the power meter
Service Mode by pressing the front panel keys in the following
sequence:
System | Service | Diag | 0 |Enter
This string means you would: press the System hard key |press
the Service soft key |press the Diag soft key |press the 0keypad
hard key |Press the Enter soft key.
