Basic safety instructions

1. The product may be operated only under

the operating conditions and in the
positions specified by the manufacturer. Its
ventilation must not be obstructed during
operation. Unless otherwise specified, the
following requirements apply to
Rohde & Schwarz products:
prescribed operating position is always with
the housing floor facing down, IP protection
2X, pollution severity 2, overvoltage
category 2, use only in enclosed spaces,
max. operation altitude max. 2000 m.
Unless specified otherwise in the data
sheet, a tolerance of ±10% shall apply to
the nominal voltage and of ±5% to the
nominal frequency.

2. Applicable local or national safety

regulations and rules for the prevention of
accidents must be observed in all work
performed. The product may be opened
only by authorized, specially trained
personnel. Prior to performing any work on
the product or opening the product, the

product must be disconnected from the
supply network. Any adjustments,
replacements of parts, maintenance or
repair must be carried out only by technical
personnel authorized by Rohde & Schwarz.
Only original parts may be used for
replacing parts relevant to safety (e.g.
power switches, power transformers,
fuses). A safety test must always be
performed after parts relevant to safety
have been replaced (visual inspection, PE
conductor test, insulation resistance
measurement, leakage current
measurement, functional test).

3. As with all industrially manufactured goods,
the use of substances that induce an
allergic reaction (allergens, e.g. nickel)
such as aluminum cannot be generally
excluded. If you develop an allergic
reaction (such as a skin rash, frequent
sneezing, red eyes or respiratory
difficulties), consult a physician immediately
to determine the cause.

1171.0000.42-02.00 Sheet 2

Safety Instructions

4. If products/components are mechanically
and/or thermically processed in a manner
that goes beyond their intended use,
hazardous substances (heavy-metal dust
such as lead, beryllium, nickel) may be
released. For this reason, the product may
only be disassembled, e.g. for disposal
purposes, by specially trained personnel.
Improper disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.

5. If handling the product yields hazardous
substances or fuels that must be disposed
of in a special way, e.g. coolants or engine
oils that must be replenished regularly, the
safety instructions of the manufacturer of
the hazardous substances or fuels and the
applicable regional waste disposal
regulations must be observed. Also
observe the relevant safety instructions in
the product documentation.

6. Depending on the function, certain products
such as RF radio equipment can produce
an elevated level of electromagnetic
radiation. Considering that unborn life
requires increased protection, pregnant
women should be protected by appropriate
measures. Persons with pacemakers may
also be endangered by electromagnetic
radiation. The employer is required to
assess workplaces where there is a special
risk of exposure to radiation and, if
necessary, take measures to avert the
danger.

7. Operating the products requires special
training and intense concentration. Make
certain that persons who use the products
are physically, mentally and emotionally fit
enough to handle operating the products;
otherwise injuries or material damage may
occur. It is the responsibility of the
employer to select suitable personnel for
operating the products.

8. Prior to switching on the product, it must be
ensured that the nominal voltage setting on
the product matches the nominal voltage of
the AC supply network. If a different voltage
is to be set, the power fuse of the product
may have to be changed accordingly.

9. In the case of products of safety class I with
movable power cord and connector,
operation is permitted only on sockets with
earthing contact and protective earth
connection.

10. Intentionally breaking the protective earth
connection either in the feed line or in the
product itself is not permitted. Doing so can
result in the danger of an electric shock
from the product. If extension cords or
connector strips are implemented, they
must be checked on a regular basis to
ensure that they are safe to use.

11. If the product has no power switch for
disconnection from the AC supply, the plug
of the connecting cable is regarded as the
disconnecting device. In such cases, it
must be ensured that the power plug is
easily reachable and accessible at all times
(length of connecting cable approx. 2 m).
Functional or electronic switches are not
suitable for providing disconnection from
the AC supply. If products without power
switches are integrated in racks or systems,
a disconnecting device must be provided at
the system level.

12. Never use the product if the power cable is
damaged. By taking appropriate safety
measures and carefully laying the power
cable, ensure that the cable cannot be
damaged and that no one can be hurt by
e.g. tripping over the cable or suffering an
electric shock.

13. The product may be operated only from
TN/TT supply networks fused with max.
16 A.

14. Do not insert the plug into sockets that are
dusty or dirty. Insert the plug firmly and all
the way into the socket. Otherwise this can
result in sparks, fire and/or injuries.

15. Do not overload any sockets, extension
cords or connector strips; doing so can
cause fire or electric shocks.

16. For measurements in circuits with voltages
V

> 30 V, suitable measures (e.g.

rms

appropriate measuring equipment, fusing,
current limiting, electrical separation,
insulation) should be taken to avoid any
hazards.

17. Ensure that the connections with
information technology equipment comply
with IEC 950/EN 60950.

18. Never remove the cover or part of the
housing while you are operating the
product. This will expose circuits and
components and can lead to injuries, fire or
damage to the product.

1171.0000.42-02.00 Sheet 3

Safety Instructions

19. If a product is to be permanently installed,
the connection between the PE terminal on
site and the product's PE conductor must
be made first before any other connection
is made. The product may be installed and
connected only by a skilled electrician.

20. For permanently installed equipment
without built-in fuses, circuit breakers or
similar protective devices, the supply circuit
must be fused in such a way that suitable
protection is provided for users and
products.

21. Do not insert any objects into the openings
in the housing that are not designed for this
purpose. Never pour any liquids onto or into
the housing. This can cause short circuits
inside the product and/or electric shocks,
fire or injuries.

22. Use suitable overvoltage protection to
ensure that no overvoltage (such as that
caused by a thunderstorm) can reach the
product. Otherwise the operating personnel
will be endangered by electric shocks.

23. Rohde & Schwarz products are not
protected against penetration of water,
unless otherwise specified (see also safety
instruction 1.). If this is not taken into
account, there exists the danger of electric
shock or damage to the product, which can
also lead to personal injury.

24. Never use the product under conditions in
which condensation has formed or can form
in or on the product, e.g. if the product was
moved from a cold to a warm environment.

funcionamiento).

3. Como en todo producto de fabricación
industrial no puede ser excluido en general
de que se produzcan al usarlo elementos
que puedan generar alergias, los llamados
elementos alergénicos (por ejemplo el
níquel). Si se producieran en el trato con
productos R&S reacciones alérgicas, como
por ejemplo urticaria, estornudos frecuentes,
irritación de la conjuntiva o dificultades al
respirar, se deberá consultar inmediatamente
a un médico para averigurar los motivos de
estas reacciones.

4. Si productos / elementos de construcción son
tratados fuera del funcionamiento definido de
forma mecánica o térmica, pueden generarse
elementos peligrosos (polvos de sustancia
de metales pesados como por ejemplo
plomo, berilio, níquel). La partición elemental
del producto, como por ejemplo sucede en el
tratamiento de materias residuales, debe de
ser efectuada solamente por personal
especializado para estos tratamientos. La
partición elemental efectuada
inadecuadamente puede generar daños para
la salud. Se deben tener en cuenta las
directivas nacionales referentes al
tratamiento de materias residuales.

5. En el caso de que se produjeran agentes de
peligro o combustibles en la aplicación del
producto que debieran de ser transferidos a
un tratamiento de materias residuales, como
por ejemplo agentes refrigerantes que deben
ser repuestos en periodos definidos, o
aceites para motores, deberan ser tenidas en
cuenta las prescripciones de seguridad del
fabricante de estos agentes de peligro o
combustibles y las regulaciones regionales
para el tratamiento de materias residuales.
Cuiden también de tener en cuenta en caso
dado las prescripciones de seguridad
especiales en la descripción del producto.

6. Ciertos productos, como por ejemplo las
instalaciones de radiación HF, pueden a
causa de su función natural, emitir una
radiación electromagnética aumentada. En
vista a la protección de la vida en desarrollo
deberían ser protegidas personas
embarazadas debidamente. También las
personas con un bypass pueden correr

peligro a causa de la radiación
electromagnética. El empresario está
comprometido a valorar y señalar areas de
trabajo en las que se corra un riesgo de
exposición a radiaciones aumentadas de
riesgo aumentado para evitar riesgos.

7. La utilización de los productos requiere
instrucciones especiales y una alta
concentración en el manejo. Debe de
ponerse por seguro de que las personas que
manejen los productos estén a la altura de
los requerimientos necesarios referente a
sus aptitudes físicas, psíquicas y
emocionales, ya que de otra manera no se
pueden excluir lesiones o daños de objetos.

los fusibles correspondientes del prodcuto.

9. Productos de la clase de seguridad I con
alimentación móvil y enchufe individual de
producto solamente deberán ser conectados
para el funcionamiento a tomas de corriente
de contacto de seguridad y con conductor
protector conectado.

10. Queda prohibida toda clase de interrupción
intencionada del conductor protector, tanto
en la toma de corriente como en el mismo
producto ya que puede tener como
consecuencia el peligro de golpe de corriente
por el producto. Si se utilizaran cables o
enchufes de extensión se deberá poner al
seguro, que es controlado su estado técnico
de seguridad.

11. Si el producto no está equipado con un
interruptor para desconectarlo de la red, se
deberá considerar el enchufe del cable de
distribución como interruptor. En estos casos
deberá asegurar de que el enchufe sea de
fácil acceso y nabejo (medida del cable de
distribución aproximadamente 2 m). Los
interruptores de función o electrónicos no
son aptos para el corte de la red eléctrica. Si
los productos sin interruptor están integrados
en construciones o instalaciones, se deberá

Technical Information

Audio Analyzer UPL16

Acoustic Tests of GSM Mobiles

The latest member in the family of Audio Analyzers
UPL, the new model UPL16 is especially designed
for acoustic tests of GSM mobiles. Therefore the
instrument is equipped with the Digital Audio Inter­face DAI, artificial voice generator and the
necessary software routines. Together with the
Digital Radiocommunication Testers CRTx or CMU,
and completed with an artificial mouth/ear combina­tion, the UPL16 provides a complete system hand­ling the acoustic testcases according to 3GPP
TS 51.010-1, section 30, up to release 99.

• Digital Audio Interface DAI built-in

• Test cases according to 3GPP TS 51.010-1

• All kinds of analog and digital test signals

including artificial voice

• Measurements in analog and digital domain

• UPL16 is part of Type Approval System TS8916

• UPL16 + CRTx or CMU for type approval mea-

surements

• Validated Measurements via Air Interface with
Option UPL-B9

Brief description

UPL16 as part of GSM Simulator TS8916

The Audio Analyzer UPL16 offers the same superi­or analysis concept as all members of the UPL fa­mily. The instrument is able to handle both analog
and digital processing, it performs practically all
types of measurements in the audio range from
frequency response measurements through distor­tion measurements, FFT analysis, etc. All the de­tails about test functions and the concept of opera­tion can be found in the data sheet of the Audio
Analyzer UPL.
The UPL16 is especially designed for acoustic tests
of GSM mobiles. It is equipped with the Digital
Audio Interface DAI as defined in 3GPP TS 44.014.
With this interface the UPL16 can act as a system
simulator or it can simulate a mobile.
To drive an artificial head directly without the need
of additional amplifiers, the generator output of the
UPL16 is matched to the impedance of the artificial
mouth by a built-in transformer.
3GPP TS 51.010-1, section 30 defines so called
speech teleservices tests for GSM mobiles, gene­rally referred in this document as acoustic testca­ses. All measurements via DAI are supported by the
software package delivered with the instrument.
The acoustic tests via Air Interface are available
with option UPL-B9.

The application UPL16 with CRTx is fully integrated
in the TS8916 system. Performance and operation
concerning the control of UPL, activating testcases
and speech coder via CRTKAUD, as well as the
result handling are practically identical on CRTx and
TS8916.

UPL16 together with Universal
Radiocommunication Tester CMU200

This is the ideal and cost-effective combination for
testing the acoustic quality in type approval, deve­lopment, quality assurance, production, etc.
The CMU sets up a call to the mobile via the RF
link. Then the test cases are started from the user
interface of the UPL16, the results are displayed on
the audio analyzer. For some of the tests, the
speech codec is needed, which is implemented in
the CMU200 with option CMU-B52.

UPL16 in test system applications

The Audio Analyzer UPL16 can be used in system
applications in different ways:

UPL16 together with
Digital Radiocommunication Tester CRTx

This application is ideal for type approval and de­velopment labs. For CRTx the software package
CRTKAUD is required. The test cases are started
from the user interface of the CRTx, the UPL16 is
controlled via IEEE-Bus. The results are displayed
on the UPL16 and transferred to CRTx. Together
with the UPL16 acoustic measurements are now
added to the large variety of tests provided by
CRTx.

Audio Analyzer UPL16 provides all the necessary audio signals and
performs the acoustic measurements. Universal Radiocommunication
Tester CMU is used to establish the call. For some test cases also the
speech codec is used.

UPL16 General

1 Introduction

Audio Analyzer UPL 16 permits acoustic measurem ents to be performed on GSM m obile stations like
those prescribed for the type approval test in line with 3GPP TS 51.010.

The acoustic test cases described in chapter 30, Speech Teleservices, of 3GPP TS 51.010 are
measurement procedures with the aid of which specific characteristics of the mobile can be measured.

A GSM system simulator like CRTx, CMD or CMU is required for call setup to the mobile and for
executing the test cases 30.6.1 (Echo Loss) and 30.6.2 (Stability Margin) which use the speech codec.

1.1 General

This is a supplem entary manual and contains only special cases and extens ions offer ed by UPL 16 as
against the basic model UPL 06. Character istics identical to those of UPL 06 ar e described in the UPL
manual.

A distinction has to be made between references to the supplementary manual and to the UPL
operating manual. The latter is referenced to with "see UPL Manual ...".

No changes have been made to the analog section; in the digital s ection the reduced sam ple rate limits
the frequency range to 4 kHz. There are some differences in the operation of the digital section of
generator and analyzer, and in the analyzer this par ticularly concerns the conf iguration section. Settings
for the digital interface of generator and analyzer are identical and made in the OPTIONS panel.

UPL 16 comprises the following extensions as against the UPL standard model:
The instrument is equipped with a GSM DAI interf ace according to 3G PP TS 44.014 section 10 and an
audio transformer for a direct drive of the artif icial mouth. Options UPL-B4, B6 and B10 are standard
equipment. The software for acoustic m easurements via DAI interfac e in line with 3GPP TS 51.010 is
installed. For acoustic meas urem ents via air interfac e options UPL-B8 Mobile Phone T es t Set and UPL­B9 3G Mobile Phone Tests can be installed.

UPL16 may be equipped in addition with options UPL-B1 and UPL-B5. Options UPL-B2, B21, B22, B23
and B29 cannot be integrated.

UPL16 GSM Digital Audio Interface

2 Hardware Description

2.1 GSM Digital Audio Interface

The demands set on the GSM digital audio interface (DAI) are defined in 3GPP TS 44.014 specs,
chapter 10. The implementation in the UPL fully complies with this specification.

A second (auxiliary) DAI interface is available at unassigned pins.
The EMMI (electrical man machine interface) function is not implemented.

2.1.1 Logic Function

The data exchanged on the interface are 13-bit linear PCM at 8 k samples per second, which are
transferred to and from the mobile on two serial lines at 104 kbit/s (13 bit ∗ 8 kHz = 104 kbit/s).
Another line, controlled by the MS, clocks the data.
One additional line, controlled by the SS, resets the speech trans coder and the speech A/D and D/A
functions and starts data transmission.

Except for this interf ace, which is defined by 3GPP TS 44.014 and called "Interface DAI to MS" in the
UPL, two other variants are implemented in UPL. The following interfaces are therefore available:

Interface DAI to MS The UPL acts as a system simulator and can be connected to a mobile.
Interface DAI to SS The UPL simulates a m obile and can be connected to the DAI of a system

simulator (eg for test purposes).

Interface AUX to SS Second (auxiliary) DAI interface. It has the same f unction but another pin

assignment as the DAI to SS interfac e. Only the pins def ined "not us ed" by
3GPP TS 44.014 are employed.

Only one of the two interfaces (DAI or AUX) can be used at a time.
Two test control lines determine the operating mode of the mobile. They are controlled by the SS.

Having set the appropriate test control signals a reset pulse has to be applied to activate the test mode
in the mobile.

Table 1: test control lines:

Test control line Function

Low Low Normal operation (idle mode)

High Low Test of speech encoder / DTX functions (uplink)
High High Test of acoustic devices and A/D & D/A

UPL16 GSM Digital Audio Interface

2.1.2 Pin Assignment and Signal Flow

The connector for the GSM digital audio interface is placed at the rear panel. A 25-pin sub-D sock et
(male) labelled GSM DAI is used.

A second (auxiliary) DAI interface is implemented in addition to that defined by 3GPP TS 44.014. It has
the same function as the DAI to SS interface. Only one interface can be used at a time.

This auxiliary interface uses only pins which are defined as "not used" in 3GPP TS 44.014.
The pin assignment of the connector and the signal f low at the interface are shown in the two tables

below for the two interfaces:

2.1.3 Timing

Data are read in by the MS or SS at the rising edge and are output by the SS or MS at the falling edge of
the clock, as shown in the figure. T he data c ons ists of 13 bit words in two’s complem ent format, with the
most significant bit transmitted first.

Upon release of the reset pulse the data transmission starts with the first clock pulse. The delay
between reset pulse and start of data transmission is not defined.

The reset signal is active low. This state has to be longer than 4 ms. The res et signal always remains
high when no reset is sent.

The clock signal is high when no clock is sent.

UPL16 Signal Source for Artificial Mouth

2.2 Signal Source for Artificial Mouth

A audio transformer adapts the UPL generator output to the impedance of the artificial mouth
(loudspeaker). The tr ans f ormation ratio is 4:1. Thus a maximum output voltage of 2.5 V is thus available
in the idle mode. The output impedance is typically 1 Ω so that a maximum power of approx. 1 W can be
output.

At the maximum input voltage of 10 V (rms ) a frequency range from 100 Hz to beyond 10 kHz can be
used. If the transformer is overloaded and gets into a s aturated state, the generator output is switched
off. This state is signalled on the UPL by the OUTPUT OFF and GEN OVLD LEDs and the message
OUTPUT OFF in the status line of the generator.

BNC connectors are used for input and output. T hey are located are at the rear of the unit and labelled
4:1 Trans. . The generator output is connected to the transf orm er input, the output of the transf orm er to
the artificial mouth.

2.3 Test Setup for Stability Margin Measurement

The following test setup is prescribed for test case 30.6.2 (Stability Margin) in 3GPP TS 51.010: the
analog output signal of the speech decoder is am plified by 6 dB. A narrowband noise signal in line with
ITU-T Recomm endation O.131 is added to this signal. T he res ulting signal is applied to the analog input
of the speech decoder. An amplif ication of the signal at the input or output of the speech decoder m ust
also be considered when the loop gain of 6 dB is adjusted.

The whole loop between output and input of the speech coder including the user-selec table gain and
addition of noise are digitally implemented in the UPL. T he generator func tion RANDOM+ANLR is used
for this purpose.

The signal from the speec h dec oder is applied to the analyzer. It is multiplied in the UPL by a gain factor
and then the noise signal is added. The signal thus obtained is the generator output signal which is
applied to the input of the speech coder.

The signal gain measured by the analyzer and the amplitude of the noise signal are user selectable. The
measurement r ange of the analyzer and the maximum generator output level are to be selected so that
the signal is not overdriven in the analyzer or the generator.

These new testcases (available with upgrade UPL-U81 only) are com pletely described in Annex C as
well as installation, test setup, calibration and operation.

3.4 Data Transmission on the DAI

The DAI of the UPL should be configured ad follows (see 4.1.1, UPL used as System Simulator):

Interface DAI to MS
Reset START
Test Ctrl ACOUST DEVS
DAI Source AUDIO GEN

A call has to be established between the mobile and the system simulator (for signalling).
The DAI of the mobile has to be configured properly to be ready for being switched to the test mode by
the system simulator.
Note: The details of these steps depend on the DAI of the mobile to be tested.

If the DAI of the mobile is ready it will be set to the test mode by the UPL:
Set the test control lines: Test Ctrl → ACOUST DEVS
Wait more than 1 second, then send a reset pulse: Reset → START

After the rising edge of the reset pulse the m obile has to send the data cloc k and at the s am e tim e star t
data transmission. Upon the first clock edge the UPL also s tarts to transm it data. If the digital generator
is selected in the UPL, the signal set in the generator is s ent to the m obile and should be audible in the
loudspeaker when a suitable level is set.

Upon installation of the UPL software, a test setup DAI_TST1.SAC is stored in the directory
C:\UPL\SETUP which allows the function of the DAI interface to be checked in a simple way:

Load setup DAI_TST1.SAC and start sweep:

The digital generator sweeps the frequency between 300 Hz and 3 kHz.
The digital analyzer displays the measured signal as FFT.

The tones should be audible in the loudspeaker of the mobile. The echo received by the microphone of
the mobile is transmitted to the UPL via the DAI and visible in the spectrum. A whistling tone at the
microphone is visible as a line in the displayed spectrum.

3.5 Artificial Ear and Mouth

The artificial ear (microphone) is to be connected to the input of the UPL analyzer via a suitable amplifier
or a feed unit.

The artificial mouth (loudspeaker) cannot be fed directly from the output of the UPL generator. It has to
be connected to the output via the 4:1 adapter transformer accommodated in the rear panel of UPL16.

1078.2089.52 3.3 E-5

UPL16 Calibration Procedures

3.6 Calibration Procedures

The microphone of the artificial ear has to be calibrated with aid of an sound pressure calibrator
producing a sound pressure level of 94 dBspl which equals a sound pressure of 1 Pa at a frequency of 1
kHz eg. B&K 4231 or B&K 4230

3.6.1 Calibration of artificial ear and artificial mouth

3.6.1.1 Using artificial ear ITU-T Recommendation P.57 Type 1

3.6.1.1.1 Ear Calibration

If the used ear type is changed this step must be repeated!

The microphone has to be detached from the par ts of the artificial ear (Type 1) (switch power supply of
microphone off f or disassembly!). After r eassembling the measuring m icrophone and switching on the
supply the microphone has to be connected to the sound pressure calibrator which has also to be
switched on. After switching on the power supply of the microphone at leas t 1 minute settling time is
needed for the microphone to stabilize The output voltage of the microphone at the output of the
microphone preamplifier and power supply is measured and stored as reference for all subsequent
measurements.

Note: after calibration the gain of the preamplifier and other settings of the microphone supply

and preamplifier must remain unchanged for all measurements!

Calling the routine CAL_MIC measures the m icrophone output voltage, calculates the internal r efer ence
value in dBV/Pa and stores it on a file as reference for all later measurements. The microphone
sensitivity in mV/Pa is calculated and shown on the screen for validation with the value delivered with
the calibration chart of the microphone.

3.6.1.1.2

The absolute sensitivity and the frequency response of the artif icial mouth have to be com pensated for
all measurements . The calibration of the m outh is done with the measuring micr ophone of the artificial
ear which has to be calibrated first. The microphone must be disassembled from the ear parts.

The microphone has to be m ounted in a r ectangular pos ition to the m outh refe rence point using the tes t
fixture parts delivered with the mouth.

Calling the routine CAL_MOU measures the sound pres sure level at 1 kHz and adjusts the voltage at
the mouth input until the sound pressure equals 1 Pa (94 dBspl). This voltage is stored on file for
subsequent measurements as mouth sensitivity value.
In the next step the output voltage of the mouth is s et to -4.7 dB relative to the value m easured before
thus adjusting a sound pressure level of -4.7 dBPa (measuring level for most measurements) and a
sweep using the frequencies according to P79 is performed. The measured frequency response is
internally stored as an inverted response as equalisation file f or the generator. Due to nonlinearities in
the mouth speaker small errors may still occur therefore a second response measurement with
equalisation switched on is performed and the small residual error factors due to nonlinearities are
mesured. The initial equalis ation f ile will be corr ec ted by thmeasur ed c orr ec tion f ac tors thus pr oducing a
new equalisation.

Mouth Calibration

For validation a third sweep is started using the new equalisation file. T he measured sound pressure
level is checked for an abs olute sound press ure of -4.7 dBPa ±0.2 dB. The display shows the response
and the limit lines together with a PASS or FAIL indication.

1078.2089.52 3.4 E-5

UPL16 Calibration Procedures

3.6.1.2 Using artificial ear ITU-T Recommendation P.57 Type 3.2

3.6.1.2.1 Ear Calibration Step 1

If the used ear type is changed this step must be repeated!

The microphone in the artificial ear has to be calibrated with aid of an sound pressure calibrator
producing a sound pressure level of 94 dBspl which equals a sound pressure of 1 Pa at a frequency of 1
kHz eg. B&K 4231 or B&K 4230

The microphone of type 3.2 artificial ear cannot be detached! T he ear has to be c alibr ated using adapter
DP 0939 for the calibrator. After switching on the power supply of the microphone at least 1 minute
settling time is needed for the microphone to stabilize. The calibrator has to be switched on and the
adaptor DP0939 has to be attached to the pinna of the artificial ear in a sealed condition. The output
voltage of the microphone at the output of the m icrophone pream plifier and power supply is m easured
and stored as reference for all subsequent measurements.

Note: after calibration the gain of the preamplifier and other settings of the microphone supply

and preamplifier must remain unchanged for all measurements!

Calling the routine C32L_MIC measures the m icrophone output voltage, corrects the sound pres sure
reference due to calibration value of adapter DP0939, calculates the internal refer ence value expres sed
in dBV/Pa and stores it on a file as ref erence for all later m easurements . The microphone s ensitivity in
mV/Pa is calculated and shown on the scr een for validation with the value delivered with the calibration
chart of the microphone.

3.6.1.2.2 Ear Calibration Step 2

The individual calibration data of the artificial ear are needed f or all subsequent measurements , those
data are delivered on a floppy disc together with the artificial ear. The artif icial ear according to ITU-T
Recommendation P.57 type 3.2 simulates a human ear with the microphone placed at the DRP ( Drum
Reference Point), for measurements acc ording to 3G PP T S 51.010 c hapter 30 the sound pressure level
has to be measured at the ERP (Ear Reference Point) so eac h measured value has to be trans formed
from DRP to ERP using the calibration data of the ear.

Calling the routine C32L_EAR reads the data from the calibration disc and stores the correction values
in the internal file EAR_32L.CAL on the harddisc of UPL16. The routine automatically checks the file
name OES_LL.ADA and data format on the calibration disc and displays PASS if the values are correct.

The routine does not check the date of the calibration disc and the calibration values itself, so
the user is responsible to insert the calibration disc with actual valid calibration data!

The calibration data are stored on the harddisc of the UPL16. It is not necessary to repeat this
step as long as the calibration data of the ar tificial ear type 3.2 remain unchanged!

1078.2089.52 3.5 E-5

UPL16 Calibration Procedures

3.6.1.2.3 Mouth Calibration

The calibration files for the artificial mouth are identical for both ear types. So if the mouth was
already calibrated it is not necessary to recalibrate it if the used ear type is changed!

The absolute sensitivity and the frequency response of the artif icial mouth have to be com pensated for
all measurements. For the calibration of the mouth an additional measuring microphone is needed
which has to be calibrated first. The preamplifier used with the artificial ear can be used but an additional
microphone capsule type 4134 is needed (the mic rophone capsule of artificial ear type 1 can be used if
available).

• Switch power supply of m icrophone off and unsc rew microphone pr eamplif ier from artif icial ear type

3.2.

• Complete measuring microphone with additional microphone capsule to form a usual measuring
microphone and switch power supply of micr ophone on. Allow at least 1 minute setup time for the
microphone.

• Attach this microphone to the sound level calibrator, switch calibrator on and call routine
C32L_MMO.

• Mount this microphone in a r ectangular position to the mouth referenc e point using the test fixture
parts delivered with the mouth.

Calling the routine C32L_MOU measures the sound pressure level at 1 kHz and adjusts the voltage at
the mouth input until the sound pressure equals 1 Pa (94 dBspl). This voltage is stored on file for
subsequent measurements as mouth sensitivity value.
In the next step the output voltage of the mouth is s et to -4.7 dB relative to the value m easured before
thus adjusting a sound pressure level of -4.7 dBPa (measuring level for most measurements) and a
sweep using the frequencies according to P79 is performed. The measured frequency response is
internally stored as an inverted response as equalisation file f or the generator. Due to nonlinearities in
the mouth speaker small errors may still occur therefore a second response measurement with
equalisation switched on is performed and the small residual error factors due to nonlinearities are
mesured. The initial equalis ation f ile will be corr ec ted by the m easur ed c orr ec tion f ac tor s thus producing
a new equalisation.

For validation a third sweep is started using the new equalisation file. T he measured sound pressure
level is checked for an abs olute sound press ure of -4.7 dBPa ±0.2 dB. The display shows the response
and the limit lines together with a PASS or FAIL indication.

3.6.2 Calibration of the Speech Codec in the CMD or CRTx

Some measurements have to be performed via the RF interface and thus via the speech coder/decoder.
The gain of the speech path should also be calibrated since the gain is entered directly into the
measurement r esult. For this c alibration it is neces sary to close the RF path via a m obile and to set the
mobile to a so-called loop-C status. The audio data sent to the mobile are directly returned via the RF
interface. This nearly corresponds to a total echo or an echo path with a gain of 0 dB.

The CODEC-CAL routine sets this s tatus or requests the user to perf orm this setting and then carries
out an echo loss measurem ent in c om pliance with test cas e 30.6.1 with artificial speec h. T he m easured
value directly corresponds to the gain of the speech codec and is stored in the CODEC.CAL file.

Selects the operating mode of the interface.
The UPL acts as a system simulator and can be connected to a mobile.

This operating mode, defined in 3GPP TS 44.014 section 10, should
always be used when connecting the UPL to a DAI-Mobile to perform the
acoustic test cases.
The UPL sends a reset pulse and then waits f or the data clock to start
data transmission.

UPL simulates a mobile (MS) and can be connected to a system
simulator (SS). The direction of the signals on the DAI is inverted as
against the DAI to MS status: the UPL waits for a reset pulse and then
sends the data clock at the beginning of data transmission.
In this mode a digital link can be s et up to instrum ents the DAI of which is
permanently configured as system simulator.
This allows the UPL to be connected for ins tanc e to the digital interface of
the speech coded of a system simulator.
The test control lines are switched to high impedance.

The second (auxiliary) audio interface is used. It has the same function as
the DAI to SS interface but another pin assignment.
Only the pins designated "not used" in 3GPP TS 44.014 are used for this
additional interface.

4.2.1 Selecting the Generator

GENERATOR

ANLG

DIGITAL

The standard analog generator can be supplem ented by the low-distortion generator option (UPL-B1)
for sinewave generation in the analog range, thus allowing for generating a particular low-distortion
sinewave signal with a frequency of up to 110 kHz.

In the digital mode this low-distortion generator c an also be used as an analog auxiliary generator s o
that digital and analog sinewave signals can be simultaneously generated with option UPL-B1.

Frequency range of the digital generator:
The generator attains 99% of the Nyquist frequency. The sam ple frequency is 8 kHz and displayed in

the configuration section of the GENERATOR panel using the menu item Sample-Frq. So the maxim um
generator output frequency is given by:

The GENERATOR panel contains the settings for the analog and the
digital generators.

Two-channel analog generator, 2 Hz to 21.75 kHz, with low-distortion
generator (UPL-B1 option) up to 110 kHz

Single-channel digital generator, 2 Hz to 3.96 kHz

f

= 0.5 x sample frequency x 0.99 = 3.96 kHz

max

There are 3 states the active generator (visible in the panel) can assume (see UPL Manual, section

2.3.5 Status Display):

• RUNNING: The set function (generator signal) is output via the specified interface.

• BUSY: The generator output signal is calculated.

• HALTED: The generator is halted, no output signal; the outputs are terminated.

RUNNING is the normal status of the generator, ie a signal is constantly output. The generator is
automatically restarted after a reset.

The generator can be manually restarted at all tim es by calling the generator or the function (open the
respective selection window and confirm using ENTER). This may be required with burst signals to
immediately start a new interval (with the burst phase).

The setting of som e signals (eg specif ic noise signals) involves a lot of computations. Dur ing this tim e,
the generator does not produce any signal and is in the BUSY state. After having successfully
concluded the computations, the generator automatically re-enters the RUNNING state. If further
settings are made or keys are pressed during computation, the computation is aborted and
automatically restarted. The generator shortly assumes the HALTED state.

Other reasons for halting the generator (HALTED):

• Faulty setting (eg wrong file name for an equalization or sweep list).

Remedy: eliminate the cause of error; restart, if required.

• On the digital instrument:

Applying a too high external frequency (generator is ”overrun”).
Remedy: reduce the external clock frequency and restart.

4.2.3.1 Special Features of Digital Generator Functions

The main diff erences of m odel UPL 16 as against UPL 06 with option UPL-B2 are c aused by the lower
sampling rate and the narrower word width.

The lower sampling rate of 8 kHz reduces the available frequency range to 3.96 kHz but it improves the
frequency resolution for the noise signals (RANDOM Domain FREQ, RANDOM+ANLR, MULTI SINE) by
the same degree (below 0.5 Hz). The limit frequencies for each frequency menu item are displayed in
the user information line so that further explanations are not required. Since the word width is limited to
13 bits (audio bits), the level resolution is reduced to -72.25 dBFS.

4.2.3.2 Artificial Voice

The artificial voice (m ale and fem ale) is used whenever an excitation signal is required which com es as
near as possible to reality. Such signal is required for echo loss measurements with the acous tic GSM
test cases.

The artificial voice is created via the gener ator function ARBITRARY. Two special waveform files (one
for male the other for female) in CPR format can be loaded and reproduced. They have the designations

• P50M.CPR for male and

• P50F.CPR for female

The CPR files are sent to the generator DSP online and in packed form. T he wider the word width of the
samples, the more data have to be downloaded. For this reason the word width of the artificial voice files
is reduced to the 13 bits required for GSM. Since the artificial voice signal is an analog signal, the
sampling rate must be 48 kHz.

For further inform ation on the generator function used and the CPR format see UPL Manual, section

2.5.4.10 ARBITRARY (User-programmable Signal).

4.2.3.3 Feedback of Analyzer Signal with Additional Noise

With the RANDOM+ANLR generator function, the feedback analyzer signal whose gain is selectable is
superposed on a noise signal whose frequency can be defined. T h is function is required f or the s tability­margin measurements in the acoustic test cases.

The noise signal is defined by specifying an amplitude-frequency distribution in the fr equency domain
(FREQ). This noise is always white.

The superposed analyzer signal can be taken from measurement channel 1 or 2.
This special signal can only be generated if the "Volt Range" in the GENERAT OR panel is set to FIX.

Otherwise the loop signal is set to zero gain (muting), while the noise signal remains active.

• Prior to making analyzer settings, the generator should be configured usefully. Otherwis e, undesired
generator settings could cause superfluous restrictions in the analyzer panel.

• If the generator is not used as a signal s ource, it is adv isable to switch ov er to analog mode in order
to avoid any interference of the generator settings.

Display of (nominal) analyzer clock rate .
The digital analyzer can only be operated with a (fixed) clock rate of 8

kHz. The clock may be internally generated or externally applied. The
signal source is the same f or digital generator and analyzer and can be
selected in the OPTIONS panel,.

Note: The applied digital (generator/analyzer) clock is continually

measured in the UPL irrespective whether one of the two digital
instruments is active or not. The meas ured clock frequency can
be read out as SENS4:DATA via the automatic sequence
controller or by remote control. For a display in the manual
mode, the analyzer has to be set to SAMPLE FREQ.
If not clock is present, a NAN value is supplied.

The maxim um measurement frequency of the digital analyzer is obtained from the s ample frequency
and the (modified) "Nyquist" factor:

UPL16 Analyzers (ANALYZER Panel)

4.3.3 Special Features of Digital Analyzer Functions

The main differences of model UPL 16 as against UPL 06 with option UPL-B2 are due to the lower
sampling rate and the narrower word width.

The lower sampling rate of 8 k Hz reduces the available f requency range to 3.66 k Hz but it im pr oves the
frequency resolution of the FFT-supported measurem ent functions (THD+N, DFD, MOD DIST , FFT) to
the same degree (below 0,5 Hz in the whole frequency range; 7.6 mHz at max. zoom depth). T he lim its
for frequency entries under each frequency menu item are displayed in the user info line so that no
further explanations are required.

Since the word width is limited to 13 bits (audio bits), the level resolution is reduced to -72.25 dBFS.
The measurement function COHERENCE is a 2-channel measurement it cannot be selected.

UPL16 Analyzer Filters

4.4 Analyzer Filters

The FILTER panel has been devised for definition of the filters which can then be used in the
ANALYZER panel. Before you can select a user-definable filter in the analyzer, you must, of course,
create it in the FILTER panel.

Activating the FILTER panel:

UPL front panel: FILTER
External keyboard: ALT + T
Mouse: (repeated) click on the right panel name, until the FILTER panel is displayed.

If the FILTER panel is already displayed on the screen, it can be activated also by actuating one of the
TAB keys (repeatedly) or by a mouse click.
Advantage: The panel need not be set up again.

Filter

For the functions

• RMS & S/N (rms measurement) → 3 filters possible

• PEAK & S/N (peak measurement), → 3 filters possible

• Q-PK & S/N (quasi-peak meas.) → 3 filters possible

• THD+N/SINAD (distortion measurement) → 1 filter possible

• RMS SEL (selective RMS measurement) → 1 filter possible

• FILTSIM (filter simulation) → 3 filters possible

• RUB & BUZZ (loudspeaker measurement) → 1 filter possible

• WAVEFORM (Time domain display) → 1 filter possible

• 1/3-OCTAVE → 1 filter possible

Any desired filter from the filter selection window can be set in the
ANALYZER panel. This window contains user-definable f ilters ( the fir st 9)
and weighting filters, which are referred to by their short names in the
FILTER panel or by a name complying to the standard. You can select
any desired filter (also several times) and assign it to the ANALYZER
measurement function.

The sum frequency response of all selected filters can be graphically
displayed using the FILTSIM analyzer function (see UPL Manual, section

2.6.5.13).

Note: In the WAVEFORM mode, no filter can be selected in the

110 kHz analyzer.

UPL16 Analyzer Filters

4.4.1 Weighting Filters

The user-definable filters in the UPL (see UPL Manual, section 2.7.2 Creating the User-definable
Filters) are complem ented by a set of pre-defined weighting filters, which are automatically matched to
the current sample rate. In the analog analyzer 15 different filters can be s elected; in the digital analyzer
only the CCITT filter because of the low sampling rate.

Note: The weighting filters are always available with the filter command of the respective

measuring function and need not be set in the FILTER panel.

UPL16 Fast Switch-off of Outputs

4.5 Fast Switch-off of Outputs

Switches off all outputs.

• Digital output set to OFF (0 FS).

• Analog outputs are terminated (impedance is retained);

output level = 0 V.

An LED indicates the state of the key. LED on signifies O UTPUT OFF.
The generator status is also indicated as "Output Off" (yellow) in the
status line so the state is known even if an external monitor is used and
no attention is paid to the UPL.

The outputs are automatically switched off when

• the generator is overloaded or

• the analyzer outputs are overloaded (input voltage into 300 Ω and 600
Ω > 25 V); in this case the input impedance is internally switched to

200 kΩ.

When switched off, the lines can be reactivated only by pressing the
OUTPUT OFF key again. After an overload of analyzer inputs,
measurements can be continued if the overload has been eliminated and
the input impedance switched to 200 kΩ.

Universal Sequence Controller (UPL-B10), IEC/IEEE-bus or RS232 remote control also allow write access to the result buffers.

This is of particular importance for the BASIC-macro mode:

• Measured values calculated by a BASIC macro can be indicated to the user in the usual result windows.

Any floating-point parameters and measured values can be exchanged between the BASIC macro and the controller via the result buffer.

UPL16 Calling test cases

5.15 Calling test cases

With the UPL, setting and measurement sequences can be written as BASIC programs or recorded
using the built-in program generator (see 3.15.3 Comm and Logging-Converting B10 into IEC/IEEE-Bus
Commands). Option UPL-B10 (Universal Sequence Controller) is required. The generated BASIC
programs can be stored (preferred file extension: .BAS) and called and used in various ways (see
Macro-Operation).

The following example illustr ates how a BASIC macro is called by means of an IEC/IEEE-bus control
program in the programming language C and the IEC/IEEE-bus driver GPIB.COM from National
Instruments:

UPL16 Acoustic Testcases

Annex A: Acoustic Testcases for GSM Mobiles

30.1 Sending sensitivity/frequency response

30.1.1 Definition and applicability

The sending sensitivity frequency response is, as a function of the input test tone frequency, the ratio
expressed in dB between the output level, represented by the PCM bit stream at the Digital Audio
Interface (DAI) and the input sound pressure in the artificial mouth required to obtain this.

30.1.4 Method of test

30.1.4.1 Initial conditions

a) The handset is mounted in the LRGP (see annex A of ITU-T Recommendation P.76). The

earpiece is sealed to the knife-edge of the artificial ear.

b) A pure tone with a sound pressure of -4,7 dBPa (in accordance with ITU-T Recommendation P.64)

is applied at the mouth reference point (MRP) as described in ITU-T Recommendation P.64 using
an artificial mouth conforming to ITU-T Recommendation P.51.

c) A digital measuring instrument, or high quality digital decoder followed by an analogue level

measuring set, is connected to the Digital Audio Interface (DAI). The DAI is set to the operating
mode "Test of acoustic devices and A/D & D/A ".

30.1.4.2 Procedure

The SS measures the output level r epres ented by the PCM bit stream at the DAI ( pin 23) at one- twelfth­octave intervals as given by the R40 series of preferred numbers in ISO 3 for f requencies f rom 100 Hz
to 4 000 Hz inclusive.

30.1.5 Test requirement

The sending sensitivity/frequency response (fr om MRP to the DAI) s hall be within a mask given in table

30.1. The mask can be drawn with straight lines between the breaking points in the table on a
logarithmic (frequency) vs linear (dB sensitivity) scale.
All sensitivity levels are dB on an arbitrary scale.

The frequency response is m easured and the lim it files 301.LUP and 301.LLW are invoked. Those files
contain the limit values for sending f requency response according to Table 30.1 of 3GPP TS 51.010-1.
The maximum deviation in upper and lower direction to the initial lim it values are calculated and the
measured curve is then shifted by the mean value of max upper and m ax lower deviation. After that a
new limit calculation is done. If the shifted frequenc y response is within the lim it lines PASS is dis played,
when it is outside FAIL is displayed.

30.2.4 Method of test

30.2.4.1 Initial conditions

The DAI of the MS is connected to the SS and is s et to the operating mode "Test of acoustic devices
and A/D & D/A".

30.2.4.2 Procedure

a) The sending sensitivity is measured at each of the 14 frequencies given in table 2 of ITU-T P.79,

bands 4 to 17.

b) The sensitivity is expressed in terms of dBV/Pa and the SLR is calculated according to ITU-T

Recommendation P.79 formula 4.19 b of ITU-T P.79, over bands 4 to 17, using the sending
weighting factors from ITU-T Recommendation P.79 table 2, adjusted according to table 3 of
ITU-T Recommendation P.79.

Frequencies used are stored in File P79FREQ in Hz, used values No.4 to 17:

201 1002
251 1250
315 1602
402 2002
502 2500
630 3150
802 3950

The weighting factors accor ding to table 2 in ITU-T P79 are stored in file P79W S and are read out by
the program.

1078.2089.52 A.3 E-5

UPL16 Acoustic Testcases

The measured values are converted to levels in dBV according to following calculation:
The digital level is measured via the DAI in dBFS
0 dBFS corresponds to 3.14 dBm0 ´=` 1.11193 V ´=` 0.9216 dBV this leads to the correction formula:
Level in dBV = measured value in dBFS + 0.9216 dB
The sensitivity has to be expressed in dBV/Pa. The level is measured at an acoustic sound pr essure

level of -4.7 dBPa so the sensitivity in dBV/Pa equals :
Sensitivity in dBV/Pa = measured value in dBFS + 0.9216 dB + 4.7 dB
This sensitivity is measured for each frequency, the sending loudness rating is then calculated

according to formula 4.19 b of ITU-T P79 and corrected by -0.3 dB according to table 3 of ITU-T P79
