General Safety Information
4 E1852B Operating Guide
General Safety Information
The following general safety precautions must be observed during all
phases of operation, service, and repair of this instrument. Failure to
comply with these precautions or with specific warnings elsewhere in
this manual violates safety standards of design, manufacture, and
intended use of the instrument. Agilent Technologies assumes no
liability for the customer’s failure to comply with these requirements.
WARNING T is is a Safety Class I instrument (provided wit a protective
eart ing ground, incorporated in t e power cord). T e mains plug
s all only be inserted in a socket outlet provided wit a protective
eart contact. Any interruption of t e protective conductor inside
or outside of t e instrument is likely to make t e instrument
dangerous. Intentional interruption is pro ibited.
DO NOT defeat the earth-grounding protection by using an extension
cable, power cable, or auto transformer without a protective ground
connector. If you are using an auto transformer, make sure its common
terminal is connected to the protective earth contact of the power
source outlet socket.
DO NOT operate the product in an explosive atmosphere or in the
presence of flammable gasses or fumes.
DO NOT use repaired fuses or short-circuited fuseholders: For
continued protection against fire, replace the line fuse(s) only with
fuse(s) of the same voltage and current rating and type.
DO NOT perform procedures involving cover or shield removal unless
you are qualified to do so: Operating personnel must not remove
equipment covers or shields. Procedures involving the removal of
covers and shields are for use by service-trained personnel only.

General Safety Information
E1852B Operating Guide 5
DO NOT service or adjust alone: Under certain conditions, dangerous
voltages may exist even with the equipment switched off. To avoid
dangerous electrical shock, service personnel must not attempt
internal service or adjustment unless another person, capable of
rendering first aid and resuscitation, is present.
DO NOT operate damaged equipment: Whenever it is possible that the
safety protection features built into this product have been impaired,
either through physical damage, excessive moisture, or any other
reason, REMOVE POWER and do not use the product until safe
operation can be verified by service-trained personnel. If necessary,
return the product to a Agilent Sales and Service Office for service and
repair to ensure the safety features are maintained.

Welcome
6 E1852B Operating Guide
Welcome
Welcome to the E 852B Bluetooth Test Set Operating Guide!
The E 852B Bluetooth Test Set provides a low-cost, stand-alone route
to proving the performance of Bluetooth devices with measurements
on both the transmit and receive paths.
Using the supplied PC user interface you can quickly perform critical
RF measurements such as:
• initial carrier frequency error
•FM deviation
• peak and average power
• Bit Error Rate (BER)
Functional testing includes:
• establishing a link using standard Bluetooth protocol
• using page mode for -second link set up
• using a frequency hopping source and receiver with known
performance
More detailed analysis and fault finding is possible using:
• frequency versus time
• power versus time
• power versus channel number
The CVSD CODEC allows you to send and receive audio signals via rear
panel connections and use external signal generators and analyzers to
measure the audio performance of a DUT.
To help you develop your own applications, all the commands are
logged when using the user interface in ‘debug’ mode. Using standard
Windows’ tools, you can copy the commands and paste them into a
program to quickly create an automated test sequence.

Introduction Introduction
12 E1852B Operating Guide
Introduction
The E 852B Bluetooth Test Set supports a range of different tests as
specified in the Bluetooth RF Test Specifications. It is a stand-alone
piece of test equipment and can be used for high throughput
manufacturing applications, and as a development or service tool.
For some test situations specified in the Bluetooth RF Test
Specifications, additional test equipment, such as an Agilent ESA
Spectrum Analyzer or Agilent ESG Signal Generator, can be used to
compliment the E 852B bluetooth test set measurements. Consult
Agilent Technologies for further details.
The test set is basically a Bluetooth Host Controller with added test
capabilities. Used as a test set it acts as the Bluetooth master and the
Device Under Test (DUT) acts as the Bluetooth slave.
You can operate the test set using the supplied PC user interface or by
sending SCPI format commands, either in the Windows environment
or from within a test executive.
The operation of the DUT is controlled via the Air Interface. Using the
standard test mode commands, you can set the DUT into test mode and
carry out Transmitter and Loop-back Tests.
Bluetooth RF components that are unable to establish a link can be
tested using RF Analysis and RF Generator modes.
In addition to the RF IN/OUT port for connection with the DUT, several
additional front and rear panel connections are provided. These are
shown in the Installation Guide and in External Connections on page
3. With the Counter Input on the front panel, the test set can also be
used as a frequency counter, measuring system frequencies of a
Bluetooth device up to 5MHz.
