Chapter 2. Product Overview

About Bluetooth

Bluetooth wireless technology will simplify connections between everyday appliances such
as mobile phones, PCs and PDAs. Bluetooth will not be confined to the office - home
applications will include portable music players, digital cameras, video recorders and
children’s toys. In future, Bluetooth technology will be found in the automotive, avionics
and industrial controls markets. Bluetooth technology will provide individuals with a
personal networking environment that can be found in public places, such as shopping
centers, sports stadiums and airports.

The success of the Bluetooth standard will depend on users of the technology enjoying
products that are reliable with high-quality connections that can be used “out of the box” to
provide immediate connectivity.

The combination of leading-edge RF and protocol technologies, coupled with the
requirement to get implementation costs down to a few dollars, puts particularly high
demands on the test department to develop test procedures that are comprehensive in
terms of both RF and functionality. These tests need to be fast and initiated through a
simple user interface. The integration of a module into an OEM product will not necessarily
produce predictable results, and the performance of every item will be different, this
makes it essential to test to a known set of parameters using an instrument traceable to
National Standards.

Anritsu knows the importance of test for RF products. We know that in an OEM production
environment, the key requirement will be to validate performance in the shortest time.
Production engineers will need to decide on a subset of the Bluetooth RF test specification
that is appropriate to their product’s requirements.

Working with RF, especially RF at over 2 GHz is not easy, but with Anritsu as your test
partner you can be certain of having the most up-to-date and relevant testing capabilities
for your Bluetooth products.

The MT8850A/MT8852A

Anritsu have developed the MT8850A/MT8852A, a Bluetooth Test Set to test Bluetooth
modules and Bluetooth products - quickly and at low cost.

Anritsu has a century of experience in RF technology, and today has a reputation for
developing solutions to test the newest wired and wireless technologies. Our test and
measurement products are used by customers in over 100 countries worldwide, and our
experience in the measurement business is second-to-none.

13000-000109 2-1
June 2003 About Bluetooth

MT8850A / MT8852A Bluetooth Test Set Product Overview

MT8850A/MT8852A Features

Three test modes •

• Standard mode in which the MT8850A/MT8852A uses full Test Mode signalling

and all the defined test controls to test the EUT in the fastest and most efficient
way possible.

• Single payload mode in which Test Mode signalling is performed in a very
restricted manner. The customer can define the packet length, packet payload,
select loopback or TX mode and hopping on or off.

• Null packet mode enables measurements to be made on EUTs that do not have
test mode support, by performing a limited subset of measurements on packets
without payloads. None of these measurements are performed in accordance
with the Bluetooth test specifications.

•

Fast

Keep your production lines flowing with the rapid “Quick Test” measurement script.
Production test scripts can run in as little as 10 seconds, measuring power, frequency,
modulation and receiver sensitivity (BER).

•

One touch testing

Once the MT8850A/MT8852A has been configured, each device is tested with a
single keystroke. Press Run to initiate a link, activate Test Mode, perform the
measurements and report the results.

•

Authoritative

Under standard operation, tests are made exactly as defined in the Bluetooth RF Test
Specification. All measurements are traceable to National Standards so that you can
be totally confident in both your production testing and design proving.

•

Reference Bluetooth transceiver

A custom design transceiver offers <1 kHz frequency accuracy at the start of any
packet and full compliance with the requirements for the “Dirty Transmitter” for true
receiver sensitivity measurements. In addition to the standard dirty transmitter table,
you can define customized stress conditions with user settable values of Carrier
Frequency Offset, Modulation Index, Symbol Timing Error and simulated carrier
frequency drift.

•

Remote control

Both GPIB and RS232 interfaces are offered as standard. Creating test programs has
been simplified by the ability to send single commands for initiating a test and
returning all results in a single string.

•

Small size and weight

MT8850A/MT8852A takes up minimal space in your test system thanks to its half rack
size and low weight. Where Bluetooth interfaces are being introduced into existing
products, the disturbance to the test system is minimized.

Product Overview MT8850A / MT8852A Bluetooth Test Set

•

Editing tests

Define your own test scripts to customize the test measurements to your specific
requirements. Each test can be enabled or disabled and within any test, parameters
such as hopping can be enabled or disabled, the number of measured packets
defined, and the specific frequencies of testing set up.

•

Making a link

The BT address can be acquired by entering it manually at the keyboard, by
performing an inquiry, or by means of an RS232 or USB HCI link. Once the EUT BT
address is known a Bluetooth link is established using Paging.

•

Field upgradeable

The Bluetooth protocol stack is held in FPGA so that future versions of the core
Bluetooth specification can be installed locally. The instruments main program is held
in flash memory and so product enhancements are also field downloadable.

•

Design proving

Because measurements are made in accordance with the RF Test Specification,
MT8850A/MT8852A is the ideal instrument for pre-conformance testing and design
proving. Gain confidence in your product before submitting to a Bluetooth Qualification
Test Facility for approval. To perform tests such as TX output spectrum and spurious
emissions not supported by the MT8852A, use the Anritsu ME7865A Bluetooth Pre
Qualification Test System that addresses all 16 test cases defined in the RF test
specification.

•

Audio testing (MT8852A only)

The MT8852A Bluetooth Test Set can be used to perform audio measurements by
establishing a Synchronous Connection Oriented (SCO) link between the MT8852A
and the EUT.

BlueSuite Analysis Software

A BlueSuite software package gives PC control of the MT8850A/MT8852A for advanced
design proving measurements on Bluetooth radios. Use BlueSuite to view burst power
profiles, modulation eye diagrams, display graphs of the output power of the 79
frequencies and many other advanced diagnostic tools.

Chapter 3. Installation

Introduction

This chapter provides information for the initial inspection and preparation for use of the
MT8850A/MT8852A Bluetooth Test Set. Shipping and storage information is also
included.

Initial Inspection

Inspect the shipping container for damage. If the container or cushioning material is
damaged, retain until the contents of the shipment have been checked against the packing
list and the instrument has been checked for mechanical and electrical operation.

If the Test Set is damaged mechanically, notify your local sales representative or Anritsu
Customer Service Center. If either the shipping container is damaged or the cushioning
material shows signs of stress, notify the carrier as well as Anritsu. Retain the shipping
materials for the carrier's inspection.

Power Requirements

The MT8850A/MT8852A Bluetooth Test Set is operated from AC line power. The
MT8850A/MT8852A is intended as an Installation (Overvoltage) Category II, Insulation
Category I device.

At power-on, the instrument will perform a brief power-on self test (POST). If a POST error
occurs, information and available options will be displayed on the screen. If the POST is
successful, the instrument will then go to the top-level script or single test screen that was
active when it was powered down.

AC Line Power

The MT8850A/MT8852A can operate on AC input power of 85-264V, 47-63 Hz, 150 VA
maximum. The Test Set automatically configures itself for the voltage applied. An internal
fuse protects the AC line input.

Fuse Protection

The MT8850A/MT8852A Bluetooth Test Set is protected on the AC input by an internally
mounted fuse. Only qualified service personnel should change this fuse. Replace only with
a fuse of the same type and rating, which is 5 mm x 20 mm, 250V, 2.5A T (T= time lag or
slo-blo).

Grounding

The MT8850A/MT8852A Bluetooth Test Set must be properly grounded. Failure to ground
the instrument could be hazardous to operating personnel. The instrument is supplied with
a three-wire power cord.

The instrument is properly grounded when the plug is correctly installed in a grounded
receptacle. A grounding terminal is provided on the instrument rear panel.

June 2003 Introduction

MT8850A / MT8852A Bluetooth Test Set Installation

Environmental Requirements

The MT8850A/MT8852A is designed to operate within the temperature range of 5 to 40° C
(41 to 104° F) with a maximum humidity of 90% at 40° C (104° F), non-condensing. Full
accuracy is specified at 5 to 35° C (23 to 95° F).

Although not recommended, operation in temperatures to –20°C

(–4° F) is possible. At these temperatures, however, the liquid crystal display may exhibit
excessively slow response.

CAUTION

The instrument is cooled by a fan at the rear, which circulates air
round the instrument through the vent holes in the base. The fan and
the vent holes should not be blocked.

Rack Mounting

The MT8850A/MT8852A Bluetooth Test Set can be ordered with rack mounting hardware
that allows the instrument to be mounted into a standard 19-inch equipment rack. There
are two rack mount option kits available:

The MT8850A-01 Rack Mount option allows the installation of a single
MT8850A/MT8852A in either the left or right side rack position.

The MT8850A-03 Rack Mount option allows side-by-side mounting of two
MT8850A/MT8852A Test Sets.

Single Unit Rack Mounting (Option 01)

This section describes the assembly procedure for fitting a single MT8850A/MT8852A
Bluetooth Test Set into an instrument rack. The MT8850A/MT8852A universal top and
bottom covers have removable feet to allow the rack mount kit to be fitted. The procedure
involves fitting the support bracket, front plate, base panel, and a rear support bracket to
the MT8852A. The MT8850A/MT8852A can then be loaded and secured in the rack
position.

Storage and Shipment

The following paragraphs describe preparing the MT8850A/MT8852A Bluetooth Test Set
for storage and shipment.

Preparation For Storage

Preparing the MT8850A/MT8852A Bluetooth Test Set for storage consists of cleaning the
instrument and packing it with moisture-absorbing desiccant crystals.

Environmental Requirements

Store the instrument in a temperature controlled environment that is maintained
between -40 and +70º C (-40 to ±156º F), with a maximum humidity of 90% at 40º C (104º
F), non-condensing.

Preparation for Shipment

To provide maximum protection against damage in transit, the MT8850A/MT8852A
Bluetooth Test Set should be repackaged in the original shipping container. If this
container is no longer available and the MT8850A/MT8852A is being returned to Anritsu
for repair, advise Anritsu Customer Service Center; they will send a new shipping
container free of charge. In the event neither of these two options is possible, follow the
packaging instructions below.

Use a
Suitable
Container

Protect the
Instrument

Cushion the
Instrument

Seal the
Container

Address the
container

Obtain a corrugated cardboard carton with a 125 Kg (275-pound) test
strength. This carton should have inside dimensions of no less than 150
mm (6 in) larger than the instrument dimensions to allow for cushioning.

Wrap the instrument to protect the finish.

Cushion the instrument on all sides by tightly packing dunnage or
urethane foam between the carton and the instrument. Provide at least
75 mm (3 in) of dunnage on all sides.

Seal the carton using either shipping tape or an industrial stapler.

If the instrument is being returned to Anritsu for service, mark the
address of the appropriate Anritsu service center, the Return Materials
Authorization (RMA) number, and your return address on the carton in a
prominent location.

June 2003 Running a Single Test

MT8850A / MT8852A Bluetooth Test Set Getting Started

Running a Script in Standard Mode

In Standard mode, the MT8850A/MT8852A uses full Test Mode signalling and all the
defined test controls to test the EUT in the fastest and most efficient way possible.
Standard mode is the default mode setting, although it should be noted that for devices
with only a limited implementation of test mode functionality, operation in standard mode
may result in the EUT dropping the link or failing to respond to commands from the
MT8850A/MT8852A. In this case, select single payload or null packet operation.

Running a Script in Single Payload Mode

Single payload mode uses Test Mode signalling but in a very restricted manner. This is
ideal when the test device does not yet have a full Test Mode implemented, and the
repetitive signalling in standard mode may cause it to fail or drop the link. When the user
selects to run a script in single payload mode, a message to this effect displays on the
uppermost line of every page to remind the user that a mode other than standard is
currently selected.

In this mode, the user can define the packet length, packet payload, and set loopback or
TX mode and hopping to on or off. The MT8850A/MT8852A then sends a single test
control to put the EUT into the specified state, and no further test controls are sent. When
the customer views the measurement screens, only measurements that can be made on
the selected packets are presented.

If single payload mode is selected, an additional “single payload edit” line displays on the
screen.

1. Move the cursor to the word “Edit” and press the
pages of configuration for the single payload of their choice.

2. When the payload selection is complete press
measurement screen. Only measurements supported by the selected payload are
available. Invalid measurements have oval symbols beside them.

The table below shows the single payload settings required to enable each of the tests.

.

Running a Script in Null Packets Mode

This mode is used to enable indicative measurements to be made on EUTs that have no
test mode support. In this mode the MT8850A/MT8852A does not use Test Mode
signalling at all, and makes only a limited subset of measurements on packets without
payloads. Measurements are not performed in accordance with the Bluetooth test
specification. When the user selects to run a script in null packets mode, a message to
this effect displays on the uppermost line of every page to remind the user that a mode
other than standard is currently selected.

The MT8850A/MT8852A can be made to link to an EUT and maintain the link by sending
POLL packets. In response to a POLL packet, the EUT will return a NULL packet. A NULL
Packet has no payload but can be used for power, initial frequency, drift, and modulation
measurements without having to activate test mode.

Setting Up Authentication

Authentication is the process of configuring a Bluetooth unit to connect only to one
specified device. A headset, for example, can be configured to connect only to a specific
mobile phone, and in this case, verification processing is used to ensure that the correct
connections have been established. The MT8850A/MT8852A can be configured to use
authentication during the establishment of a connection.

Note: The MT8850A/MT8852A does not use authentication by default.

The process of authentication involves creating a common key, referred to as the link key,
between the master and slave devices. Security could be compromised if this link key
were sent between devices, so instead, it is generated from a random number and a
Personal Identification Number (PIN) which can be entered into the MT8850A/MT8852A.
If authentication is required but the Bluetooth devices do not have a common link key, the
authentication procedure is completed using the PIN input, and a link key is then created
and stored during the authentication procedure. The link key stored in the Bluetooth
device can then be used during any future connection. Follow the procedure below to
configure the MT8850A/MT8852A to use authentication.

1. Press the

2. Choose “Equipment Under Test (EUT)”.

3. Press the

Test control delay

The Test Control delay value can be between 0 and 100. When the MT8850A/MT8852A
sends a Test Control command (Loopback, TX or Test Pause) the EUT may require a
period of time to respond before it has actioned the Test Control. This time will vary
between differing Bluetooth developers implementations. Test control delay causes the
MT8850A/MT8852A to pause from measuring returned packets until the EUT has had
time to respond. The number entered is the number of transmitted packets from the
MT8850A/MT8852A that are ignored before measurements are started.

Test Pause Test Control

The Test Pause test control is defined in the Bluetooth specification to improve the
efficiency of device testing. If an EUT does not support test pause, use of test pause can

Testing in Standard Script Mode

Individual tests can be tailored to suit requirements. The setup procedures and limits are
described on the following pages:

Output Power Test (Standard Mode)

The output power test performs power measurements on the EUT transmitted packets in
one of four ways.

With “Hopping On” mode set to “Defined” the MT8850A/MT8852A measures power only
when the link hops to one of the frequencies defined on the LOW, MEDIUM and HIGH set
up screen. Although the measurements are only made at the defined frequencies, it is still
a hopping link. The number of packets measured at each frequency is set by the user in
the “Number of packets” field. This is the test method described in the Bluetooth RF Test
Specification.

With “Hopping On” mode set to “All” the MT8850A/MT8852A measures the power at every
one of the 79 frequencies in the Bluetooth channel structure. The number of packets
measured at each frequency is set by the user in the “Number of packets” field.

With “Hopping On” mode set to “Any” the MT8850A/MT8852A measures the power at the
next frequency that the link hops to after the previous power measurement has been
completed. The total number of packets measured is set by the user in the “Number of
packets” field. This is typically the shortest of the three options as there is no requirement
to measure a large number of packets at specified frequencies.

The MT8850A/MT8852A can perform the test using either loopback test controls or TX
test controls. The default form for this test is to use loopback. The following test
description is described using the default test control.

The MT8850A/MT8852A transmits a pseudo random data payload (PRBS 9) of the
longest supported type (DH5, DH3 or DH1) or the selected packet type, to the EUT. The
EUT loops back the data at its maximum output power and the MT8850A/MT8852A
measures the received power. This test is performed while hopping, and the test is
repeated until the requested number of packets has been measured on each of the
selected frequencies. The LOW, MEDIUM and HIGH frequencies relate to the default
frequencies specified in the Bluetooth RF test specification. The MT8850A/MT8852A
allows all these frequencies to be changed from their default values.

Power Control Test (Standard Mode)

The power control test performs power measurement cycles on the EUT output, if the EUT
supports power control, at each of the defined frequencies (LOW, MEDIUM and HIGH).
This measurement is always performed with hopping off. The MT8850A/MT8852A can
perform the test using either loopback test control or TX test control. The default form for
this test is to use loopback. The following test is described using the default test control.

The MT8850A/MT8852A transmits a DH1 (or the operator selected packet type) packet
with a pseudo random data payload (PRBS 9). This test is performed with hopping off.
The LOW, MEDIUM and HIGH frequency sets relate to the default frequencies specified in
the Bluetooth RF test specification. The MT8850A/MT8852A allows all the frequencies to
be changed.

A power measurement cycle sets the EUT output power to its maximum and then steps
the power down to the minimum power and then up to the maximum again one step at a
time. For each power step a number of data packets are sent to the EUT and looped back
to the MT8850A/MT8852A.

When the test is performed in TX test mode only the TX
frequency settings are used since both RX and TX frequencies
must be the same.

Initial Carrier Test (Standard Mode)

The initial carrier test performs a frequency accuracy test on a DH1 pseudo random data
packet. (PRBS 9) This test can be performed using either the loopback test control or the
TX test control. The default is to use the loopback test control. This test can be made with
either hopping on or off.

With hopping off, the MT8850A/MT8852A measures the initial carrier frequency error at
the three frequencies defined on the LOW, MEDIUM and HIGH set up screen. The
number of packets measured at each frequency is set by the user in the “Number of
packets” field. This is the test method described in the Bluetooth RF Test Specification for
an initial carrier frequency test with hopping off.

With hopping on, the MT8850A/MT8852A can make the measurement in one of two ways.

If Hopping On mode is set to “All”, the MT8850A/MT8852A will measure the initial carrier
frequency at every one of the 79 frequencies in the Bluetooth channel structure. The
number of packets measured at each frequency is set by the user in the “Number of
packets” field. This is the test method described in the Bluetooth RF Test Specification for
an initial carrier frequency test with hopping on.

If Hopping On mode is set to “Any” the MT8850A/MT8852A measures the power at the
next frequency that the link hops to after the previous initial carrier frequency
measurement has been completed. The total number of packets measured is set by the
user in the “Number of packets” field. This is typically the shortest option as there is no
requirement to measure a large number of packets at every frequency.

When the measurement is made using TX mode the MT8850A/MT8852A sets up the EUT
so that when the EUT is polled it transmits a DH1 packet with a pseudo random payload
for each of the frequencies selected (LOW, MEDIUM and HIGH). This test can be
performed with hopping off and on. The LOW, MEDIUM and HIGH frequencies relate to
the default frequencies specified in the Bluetooth RF test specification. The
MT8850A/MT8852A allows all the frequencies to be changed. When the test is performed
in TX test mode EUT transmitter and receiver frequencies must be the same.

Carrier Drift Test (Standard Mode)

The carrier drift test performs a frequency drift measurement over the length of the packet
received. The test can be carried out for each of the supported packet types with either
hopping on or hopping off. This test can be performed using either the loopback test
control or the TX test control. The default is to use the loopback test control.

In loopback mode with hopping off, the MT8850A/MT8852A sends DH1, DH3 and DH5

packets with a 10101010.... payload at each of the frequencies selected (LOW, MEDIUM

and HIGH). The EUT returns the DH1, DH3 or DH5 packet for measurement. The LOW,
MEDIUM and HIGH frequencies relate to the default frequencies specified in the Bluetooth
RF test specification. The number of packets of each length that are measured is set in
the “Number of packets” field. The MT8850A/MT8852A allows all the frequencies to be
changed. This is the test method described in the Bluetooth RF Test Specification for a
carrier frequency drift test with hopping off.

In loopback mode with hopping on, and hopping on mode set to “All” the
MT8850A/MT8852A sends DH1, DH3 and DH5 packets with a 10101010 payload. The
EUT returns the DH1, DH3 or DH5 packet for measurement. The MT8850A/MT8852A will
measure the carrier frequency drift for each packet length at every one of the 79
frequencies in the Bluetooth channel structure. The number of packets of each length that
are measured is set in the “Number of packets” field. This is the test method described in
the Bluetooth RF Test Specification for a carrier frequency drift test with hopping on.

In loopback mode with hopping on, and hopping on mode set to “Any” the
MT8850A/MT8852A sends DH1, DH3 and DH5 packets with a 10101010 payload. The
EUT returns the DH1, DH3 or DH5 packet for measurement. The MT8850A/MT8852A will
measure the carrier frequency drift at the next frequency that the link hops to after the
previous carrier frequency drift measurement has been completed. The number of packets
of each length that are measured is set in the “Number of packets” field.

In TX mode with hopping on or off the measurement process is the same as for loopback
except that the MT8850A/MT8852A does not send full DHX packets but just POLL
packets. The EUT has been configured by the MT8850A/MT8852A to respond to a POLL
with the appropriate DHX packet. The EUT must support TX mode part of the Test Mode
specification for this to work. The test time is much shorter when run using TX mode
compared with loopback, as the MT8850A/MT8852A does not have to send full packet
lengths. When the test is performed in TX test mode, EUT transmitter and receiver
frequencies must be the same. TX mode complies with the Bluetooth RF Test
Specification for a carrier frequency drift test.

Modulation Index Test (Standard Mode)

This test measures the modulation characteristics on the EUT output for each of the
frequency ranges selected (LOW, MEDIUM and HIGH). The MT8850A/MT8852A can
perform the test using either loopback test controls or TX test controls. The default form
for this test is to use loopback. The following test is described using the default test
control.

The MT8850A/MT8852A transmits a number of packets containing the four ones four
zeros payload (11110000), which are looped back by the EUT. Then packets with the
alternate ones and zeros (101010101) payload are transmitted and are looped back by the
EUT. These packets are the longest supported packet type as reported by the EUT during
link set up (DH1, DH3 or DH5) or the selected packet type.

This test is performed with hopping off, and the test is repeated until the number of
packets has been measured on each of the selected frequencies as set in the “Number of
packets” field. The LOW, MEDIUM and HIGH frequencies relate to the default frequencies
specified in the Bluetooth RF test specification. The MT8850A/MT8852A allows all the
