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
1171.0000.42-02.00
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.
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.
1171.0000.42-02.00
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
Vrms > 30 V, suitable measures (e.g.
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.
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.
25. Do not close any slots or openings on the
product, since they are necessary for
ventilation and prevent the product from
overheating. Do not place the product on
soft surfaces such as sofas or rugs or
inside a closed housing, unless this is well
ventilated.
26. Do not place the product on heatgenerating devices such as radiators or fan
heaters. The temperature of the
environment must not exceed the maximum
temperature specified in the data sheet.
27. Batteries and storage batteries must not be
exposed to high temperatures or fire. Keep
batteries and storage batteries away from

General
1 Introduction
Audio Analyzer UPL 16 permits acoustic measurements to be performed on GSM mobile 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 supplementary manual and contains only special cases and extensions offered by UPL 16 as
against the basic model UPL 06. Characteristics identical to those of UPL 06 are 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 section the reduced sample 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 particularly concerns the configuration 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 interface according to 3GPP TS 44.014 section 10 and an
audio transformer for a direct drive of the artificial mouth. Options UPL-B4, B6 and B10 are standard
equipment. The software for acoustic measurements via DAI interface in line with 3GPP TS 51.010 is
installed. For acoustic measurements via air interface options UPL-B8 Mobile Phone Test 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.

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 transcoder and the speech A/D and D/A
functions and starts data transmission.
Except for this interface, 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 mobile 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 function but another pin
assignment as the DAI to SS interface. Only the pins defined "not used" 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.

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 socket
(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 flow at the interface are shown in the two tables
below for the two interfaces:

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. The data consists of 13 bit words in two’s complement 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 reset signal always remains
high when no reset is sent.

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 transformation 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 saturated 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. They are located are at the rear of the unit and labelled
4:1 Trans. . The generator output is connected to the transformer input, the output of the transformer 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 amplified by 6 dB. A narrowband noise signal in line with
ITU-T Recommendation O.131 is added to this signal. The resulting signal is applied to the analog input
of the speech decoder. An amplification of the signal at the input or output of the speech decoder must
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-selectable gain and
addition of noise are digitally implemented in the UPL. The generator function RANDOM+ANLR is used
for this purpose.
The signal from the speech decoder 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 range 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.

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 mobile has to send the data clock and at the same time start
data transmission. Upon the first clock edge the UPL also starts to transmit data. If the digital generator
is selected in the UPL, the signal set in the generator is sent to the mobile 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.

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 parts of the artificial ear (Type 1) (switch power supply of
microphone off for disassembly!). After reassembling the measuring microphone 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 least 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 microphone output voltage, calculates the internal reference
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
Mouth Calibration
The absolute sensitivity and the frequency response of the artificial mouth have to be compensated for
all measurements. The calibration of the mouth is done with the measuring microphone of the artificial
ear which has to be calibrated first. The microphone must be disassembled from the ear parts.
The microphone has to be mounted in a rectangular position to the mouth reference point using the test
fixture parts delivered with the mouth.
Calling the routine CAL_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 set to -4.7 dB relative to the value measured 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 for 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 equalisation file will be corrected by thmeasured correction factors thus producing a
new equalisation.
For validation a third sweep is started using the new equalisation file. The measured sound pressure
level is checked for an absolute sound pressure of -4.7 dBPa ±0.2 dB. The display shows the response
and the limit lines together with a PASS or FAIL indication.

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! The ear has to be calibrated 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 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 C32L_MIC measures the microphone output voltage, corrects the sound pressure
reference due to calibration value of adapter DP0939, calculates the internal reference value expressed
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.
3.6.1.2.2 Ear Calibration Step 2
The individual calibration data of the artificial ear are needed for all subsequent measurements, those
data are delivered on a floppy disc together with the artificial ear. The artificial 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 according to 3GPP TS 51.010 chapter 30 the sound pressure level
has to be measured at the ERP (Ear Reference Point) so each measured value has to be transformed
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 artificial ear type 3.2 remain unchanged!

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 artificial mouth have to be compensated 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 microphone capsule of artificial ear type 1 can be used if
available).
•
•
•
•
Switch power supply of microphone off and unscrew microphone preamplifier from artificial ear type
3.2.
Complete measuring microphone with additional microphone capsule to form a usual measuring
microphone and switch power supply of microphone 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 rectangular position to the mouth reference 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 set to -4.7 dB relative to the value measured 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 for 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 equalisation file will be corrected by the measured correction factors thus producing
a new equalisation.
For validation a third sweep is started using the new equalisation file. The measured sound pressure
level is checked for an absolute sound pressure 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 result. For this calibration it is necessary to close the RF path via a mobile 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 status or requests the user to perform this setting and then carries
out an echo loss measurement in compliance with test case 30.6.1 with artificial speech. The measured
value directly corresponds to the gain of the speech codec and is stored in the CODEC.CAL file.

DAI to MS
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 for the data clock to start
data transmission.
DAI to SS
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 set up to instruments the DAI of which is
permanently configured as system simulator.
This allows the UPL to be connected for instance to the digital interface of
the speech coded of a system simulator.
The test control lines are switched to high impedance.
AUX to SS
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
The GENERATOR panel contains the settings for the analog and the
digital generators.
ANLG
Two-channel analog generator, 2 Hz to 21.75 kHz, with low-distortion
generator (UPL-B1 option) up to 110 kHz
DIGITAL
Single-channel digital generator, 2 Hz to 3.96 kHz
The standard analog generator can be supplemented 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 can also be used as an analog auxiliary generator so
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 sample frequency is 8 kHz and displayed in
the configuration section of the GENERATOR panel using the menu item Sample-Frq. So the maximum
generator output frequency is given by:
fmax = 0.5 x sample frequency x 0.99 = 3.96 kHz
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 times 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 some signals (eg specific noise signals) involves a lot of computations. During this time,
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.

Frequency shift keying, only with UPL-B33 installed;
only required for ITU-T O33 (via automatic sequence controller).
RANDOM+ANLR
Random noise with feedback of analyzer signal; required for acoustic
GSM measurement "stability margin".
4.2.3.1 Special Features of Digital Generator Functions
The main differences of model UPL 16 as against UPL 06 with option UPL-B2 are caused 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 (male and female) is used whenever an excitation signal is required which comes as
near as possible to reality. Such signal is required for echo loss measurements with the acoustic GSM
test cases.
The artificial voice is created via the generator 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. The 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 information 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. This function is required for the stabilitymargin measurements in the acoustic test cases.
The noise signal is defined by specifying an amplitude-frequency distribution in the frequency 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 GENERATOR panel is set to FIX.
Otherwise the loop signal is set to zero gain (muting), while the noise signal remains active.

See UPL Manual, section 2.5.4.1.2
Generator Functions
Common Parameters for All
Definition of the frequency grid, ie the spacing between the frequency
lines.
USER DEF
Manual setting of frequency grid. Any value entered is adjusted to match
the nearest settable value. The limits and the settable frequency values
depend on the sampling rate (see UPL Manual, section 2.5.1 Selecting
the Generator ) and the generator selected. The lower frequency limit for
the digital instrument is the ratio
system clock / 16384
Units: Hz, kHz
ANLR TRACK
The analysis grid value of the FFT is transferred automatically. This value
is also displayed on the ANALYZER panel under "FFT:Resolution" (see
UPL Manual, section 2.6.5.12 FFT). This is the optimal setting for an
analysis with the rectangular window. If FFT is not selected in the
analyzer, the setting is rejected (error message).
Crest Fact
Selecting the algorithm to define the phase of each of the frequency lines
and so the crest factor of the total signal.
OPTIMIZED
Automatic minimization of the crest factor by internally optimizing each of
the phases.
VALUE:
Entering the desired crest factor. The phases of the frequency lines are
modified internally such that the resulting crest factor closely
approximates the desired value. The accuracy of this method depends
on the total number of lines thus spacing and frequency range
Lower Freq
Setting the lower frequency limit for the generated noise.
Range: 350 Hz to 550 Hz - 1 x spacing

E-5
UPL16
Upper Freq
Generators (GENERATOR Panel)”)
Setting the upper frequency limit for the generated noise.
Range: lower freq + 1 x spacing to 550 Hz
RND PEAK
Setting the peak output level of the noise signal. The value input here will
not affect the loop signal.
VOLT PEAK and VOLT RMS are coupled via the crest factor (which is
constant for a particular noise signal). Therefore, if VOLT PEAK is
modified, the value of VOLT RMS will also change immediately. If the
crest factor is changed, RND PEAK will remain unchanged.
Specified range: 0 to Vmax
digital: Vmax = 1 FS
analog: Vmax = 14,142 V for UNBAL
Vmax = 28,284 V for BAL
Units:
digital: FS | %FS | dBFS | LSBs | Bits | ∆% | dBr
analog: V | mV | µV | V/Vr | dBu | dBV | dBr | dBm |
∆%V | ∆V | ∆mV | ∆µV
RND RMS
Setting the RMS output voltage (for analog generator only). The value
input here will not affect the loop signal.
VOLT PEAK and VOLT RMS are coupled via the crest factor (which is
constant for a particular noise signal). Therefore, if VOLT RMS is
modified, the value of VOLT PEAK will also change immediately.
Units:
digital: FS | %FS | dBFS | LSBs | Bits | ∆% | dBr
analog: V | mV | µV | V/Vr | dBu | dBV | dBr | dBm |
∆%V | ∆V | ∆mV | ∆µV
Note:
1078.2089.52
VOLT RMS can only be entered while the generator is
RUNNING. When the noise signal is being calculated (GEN
BUSY), the crest factor is still not known; entries for VOLT
RMS will therefore be rejected at this stage and the voltage
registered as 0.0. To make sure the noise signal calculated
by the generator is output at the correct (peak) amplitude, it
is best to enter a value under VOLT PEAK, which can be
done at any time.

Note:
As soon as "Volt Range" (on the GENERATOR panel) is
switched to AUTO, loop gain is automatically set to 0 by the
program (muting).
4.2.4 Auxiliary Generator
With option UPL-B1 (low-distortion generator) fitted, an additional sinewave generator is available for
producing analog signals up to 110 kHz. Thus, digital audio data of any signal shape and an analog
sinewave signal can be generated simultaneously.
The auxiliary generator has the same specifications as the low-distortion generator and its own
(1-dimensional) sweep system for sweeping either the level or frequency. The generator can be used as
a balanced or unbalanced source with one or two output channels. Different source impedances can be
selected. Level control is via the output amplifier.
AUX GEN
Activation of auxiliary generator.
OFF
Auxiliary generator switched off; only digital audio data are generated,
analog outputs switched off.
ANALOG OUT
In addition to the digital signal an analog signal is generated at the analog
XLR connector.
Frequency and level of the analog signal can be set or swept.
All other functions of the auxiliary generator when used as analog generator are unchanged and can be
looked up in the UPL manual (see UPL Manual, section 2.5.5.1 Auxiliary Generator used as Analog
Generator.

4.3.2 Configuration of Digital Analyzer
Notes:
• Prior to making analyzer settings, the generator should be configured usefully. Otherwise, undesired
generator settings could cause superfluous restrictions in the analyzer panel.
• If the generator is not used as a signal source, it is advisable to switch over to analog mode in order
to avoid any interference of the generator settings.

The received signal can be subjected to a coding simulation before it is
handled by the measurement routines.

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

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 measured 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 maximum measurement frequency of the digital analyzer is obtained from the sample frequency

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 kHz reduces the available frequency range to 3.66 kHz but it improves the
frequency resolution of the FFT-supported measurement 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). The limits
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.

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 OUTPUT 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.

From the BASIC macro, up to 1024 floating-point values can be transferred to No manual
the external control program. The BASIC macro enters the values into the
control
block buffer which are then read out by the external control program.
For detailed program example see Appendix C.
Starting a BASIC macro with this command is only possible via IEC/IEEE-bus
or RS232 remote control. A program of the Universal Sequence Controller
UPL-B10 cannot start a BASIC macro!
This command allows to load and start any BASIC program with the name
<filename> (preferred file extension: *.BAS). After completion of the program,
a 1 → 0 transition is generated in the "RUN" bit (#14) of the operation
register. The controller receives this information by SRQ or serial poll and can
fetch the measurement data. The data exchange between the external control
program and the BASIC program can be performed via the result display, the
result buffer or the block data input/output by means of the following
command "SYST:PROG <n>{,<n>}".

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 represented 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 frequencies from 100 Hz
to 4 000 Hz inclusive.
30.1.5 Test requirement
The sending sensitivity/frequency response (from MRP to the DAI) shall 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 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 pressure
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

Calculation of RLR:
The digital level is generated via the DAI in dBFS
0 dBFS corresponds to 3.14 dBm0 ´=` 1.11193 V ´=` 0.9216 dBV this leads to the correction formula:
0 dBV corresponds to 0 dBFS - 0.9216 dB
Source level in dBFS = value in dBm0 -3.14 dB
-16 dBm0 ´=` -19.14 dBFS
The analyzer measures the sound pressure level in the ear in dBPa.
The sensitivity has to be expressed in dBPa/V. The generator level is set to -19.14 dBFS so the
sensitivity in dBPa/V equals :
Sensitivity in dBPa/V = measured value in dBPa + 19.14 dB - 0.9216 dB
This sensitivity is measured for each frequency, the receiving loudness rating is then calculated
according to formula 4.19 c of ITU-T P79 and corrected by -0.3 dB according to table 3 of ITU-T P79
Depending on the volume setting the RLR has to be within 2 ± 3 dB at nominal setting of volume control
or ≥ -13 dB at maximum volume setting.
Using artificial ear ITU-T Recommendation P.57 Type 3.2:
Each measured value is corrected by the individual correction data of the artificial ear using calibration

30.5.2.4 Method of test
30.5.2.4.1 Initial conditions
The DAI of the MS is connected to the SS and is set to the operating mode "Test of acoustic devices

MS.
30.5.2.4.2 Procedure
a) The sound field is calibrated in the absence of any local obstacles. The averaged field shall be
uniform to within +4 dB/-2 dB within a radius of 0,15 m of the MRP, when measured in one-third
octave bands from 100 Hz to 8 kHz (bands 1 to 20).
b) A calibrated half-inch microphone is mounted at MRP. The sound field is measured in one-third
octave bands. The spectrum shall be "Pink noise" as described in ITU-T recommendation P.64
annex B to within +/-1 dB and the level shall be adjusted to 70 dBA (-24 dBPa(A)). The tolerance on

d) Measurements are made in one-third octave bands for the 14 bands centred at 200 Hz to 4 kHz
(bands 4 to 17). For each band the sound pressure in the artificial ear shall be measured by
connecting a suitable measuring set to the artificial ear.
e) The listener sidetone path loss is expressed in dB and the LSTR shall be calculated from the
ITU-T Recommendation P.79 formula 8-4, using the weighting factors in column (3) in table 6 of

The leakage correction factors according to table 4 in ITU-T P79 are stored in file P79LE and are read
out by the program.
Calculation of LSTR:
The analyzer measures the sound pressure level in the ear in dBPa in the third octave bands 4 to 17.
The sound field is adjusted to an total A-weighted sound pressure level of 70 dBA. Due to pink noise the
level in each 1/3-octave band must be equal. In order to calculate the listener side tone path loss in each
1/3-octave band the level of each single 1/3-octave band has to be calculated.
Using weighting factors K1 to K14 for the A-curve weighting in the 1/3-octave bands and the Level L of a
single 1/3-octave band the total sound pressure level is:
2
2
2
Ltot(A) = L x SQR(K1 + K2 + .... K14 )
or the level of a single 1/3-octave band is:
2
2
2
L = Ltot(A) / SQR(K1 + K2 + .... K14 )
2
2
2
The correction factor SQR(K1 + K2 + .... K14 ) can be calculated out of the nominal values of
correction values for curve A according to publication IEC 179 at the mean frequency of each
1/3-octave band, this leads to the corection:
L = Ltot(A) / 3.373
or
L = Ltot(A) - 10.56 dB
The listener sidetone path loss LmeST has to be expressed in dB. The total A-weighted sound pressure
level of the noise field is adjusted to 70 dB which corresponds to -24 dBPa, the level of each 1/3-octave
band is therefore:
L = -24 - 10.56 dBPa = -34.56 dBPa
so the listener sidetone path loss equals :
LmeST = -1 x (measured value in dBPa + 34.56 dB)
This listener sidetone path loss is calculated for third octave bands 4 to 17 (centered at 200 Hz to 4000
Hz), LSTR is then calculated according to formula 8-4 of ITU-T P79.
LSTR shall not be less than 15 dB.

Each measured value is corrected by the individual correction data of the artificial ear using calibration

Initial conditions
The DAI of the MS is connected to the SS and is set to the operating mode "Normal operation". The SS
sets up a speech call according to the generic call set up procedure. The handset is mounted in the
LRGP (see annex 1 of ITU-T P.76) and the earpiece is sealed to the knife-edge of the artificial ear
conforming to ITU-T P.51.
Where a user controlled volume control is provided it is set to maximum.
30.6.1.4.2
Procedure
An implementation of the ITU-T P.50 artificial speech is connected to the analogue or digital input of the
reference speech encoder of the SS. This implementation is either a real time algorithm producing the
artificial speech or a pre-recorded tape of artificial speech. Both "male" and "female" artificial speech is
required.
A ten second segment of the "male" artificial speech is applied to the analogue or digital input of the
reference speech encoder of the SS. The third octave power of the input signal is measured. The echo
loss signal is not measured at this stage as the first ten second segment is used to allow any acoustic
echo cancellation devices within the MS to adapt to the echo path.
Immediately after a second ten second segment of the "male" artificial speech is applied to the analogue
or digital input of the reference speech encoder of the SS. The third octave power of the echo signal is
measured at the digital output of the reference speech decoder of the SS.
The difference between the third octave input power and the third octave output power is entered into
the ITU-T G.122 TCL algorithm and the acoustic echo loss calculated.
The test is repeated with the "female" artificial speech and the results of both "male" and "female"
averaged to give the final result.

Acoustic Testcases
Prior to measurement of Echo Loss the speech encoder / decoder path has to be calibrated. The
calibrating procedure uses the same artificial voices but the test mobile is set to the mode “echo back”.
In this mode the digital audio signal fed to the mobile via the RF is sent back thus simulating an echo
loop with 0 dB gain. The peak output voltage of the artificial voice generator is set to equal to full scale of
the speech encoder input. Thus under this loop condition the actual gain of the encoder / decoder loop
is measured and stored as reference for the echo loss measurement. This gain value is stored on file
and will be used for all subsequent measurements. Normally this calibration has only to be repeated if
there were any changes in hardware or used instruments, the type of test mobile should not influence
this calibration.

BASIC control program for test cases
The control program MAIN.BAS and MAIN32.BAS is supplied with UPL16. With this program all the test
cases can be executed using Radiocommunication Tester CMD 52, 55, 65 or CMU200. The optional
Real-Time Speech Coder/Decoder CMD-B52 or CMU-B52, is required for the test cases Echo Loss and
Stability Margin.
The MAIN.BAS program requires the use of ear type 1, whereas the MAIN32.BAS program requires ear
type 3.2 low leakage.
A standard PC keyboard has to be connected to UPL16 for starting and loading the program.
The program itself and the subprograms required for running the tests are stored in the directory
C:\GSM of UPL. If a different working directory was used in the UPL before, directory C:\GSM has to be
selected prior to program loading. The path can be changed in the following ways:
• in the manual mode with the "Working Dir" command in the FILE panel
• by calling up a setup required for the test cases
• from the universal sequence controller with the BASIC command line
UPL OUT "MMEM:CDIR ’C:\GSM""
• under BASIC via the SHELL command by entering CD C:\GSM and EXIT
• at DOS by entering CD C:\GSM
Starting the program:
Call up the programming interface of UPL16 with function key F3 on the PC keyboard. If you want to use
artificial ear type 1, load the MAIN program by entering LOAD"MAIN" <RETURN> and start it with RUN
<RETURN>. The program MAIN32 is used for artificial ear type 3.2. If a DOS error message is
displayed during program loading, it can be assumed that the working directory is not correct. In this
case change the directory with command UPL OUT "MMEM:CDIR ’C:\GSM <RETURN> as described
above.
To ensure proper function of the program all connectors must be correctly fitted and all instruments,
microphone feeds, etc, must be switched on. A suitable cable is required for the test cases Echo Loss
and Stability Margin which has to be connected to the multifunction connector of CMD or CMU.

Measurements:
The individual measurements are called up with the respective function keys on the UPL or the
keyboard.
Prior to starting the measurements, a call has to be set up to the test mobile by the CMD or CMU and
the speech mode "Handset" selected on. It is advisable to prepare a setup for the CMD or CMU that can
then be used for the measurements.
Make sure that the test mobile is in the CALL state and that the DAI interface is properly initialized and
connected to the DAI interface of UPL16. Each time a measurement is started, the presence of the DAI
clock of the test mobile is checked. If the clock is not present, FAIL is indicated and an error message
output.
The frequency response measurement results are graphically displayed after each test or numerically
output together with a PASS or FAIL mark, depending on whether the test conditions have been met or
not.
After completion of each measurement there is the choice to make a hardcopy, to store results or to
continue the program.
Pressing the CONT key brings back the selection menu for the measurement.
When the TRC_FILE key is pressed, the displayed trace is saved in ASCII format in a file. This file has
the name TRCxx.TRC, with xx representing a consecutive number (of max. 5 digits). This allows
processing of measurement results with other programs. The TRC_FILE key has to function when the
results are numerically displayed.
The screen content can be copied into a PCX file using the PCX_FILE key. This file has the fixed name
PICxx.PCX, with xx representing a consecutive number (of max. 5 digits). Thus the measurement
results can also be used in word processing programs, for instance. To allow also numeric values to be
stored in a PCX file, the whole screen content without the softkey line is copied.
Since both the TRC and the PCX files are consecutively numbered, it is useful to copy the files of a
measurement sequence, for instance, and to save them under a new name. In this case the original
TRCxx.TRC and PICxx.PCX files can be cleared. Thus results can be identified more easily and a mix
up between them avoided. (The files can be copied and renamed using common DOS commands.)
The screen content can be output to a printer by pressing the HARDCOPY key.
Printer type and desired settings are not selected by the program but the printer selected last and set in
UPL manual mode will be chosen. For this reason the desired printer, scaling and format should be
manually set once in the OPTION panel of UPL prior to the measurement.
Entering EXIT <RETURN> brings back BASIC without the program being cleared. The program can be
restarted immediately by entering RUN.

Overview
1 Overview
The Audio Analyzer UPL16 was developed for acoustic measurements on
GSM mobiles with DAI (digital audio interface). The UPL16 has a DAI in line
with GSM phase 2, 11.10 section 36.4 (now 3GPP TS 44.014 section 10).
Together with the Radiocommunication Tester CRTC, the UPL16 provides
all acoustic tests on GSM phase 2 mobiles. The test cases required for type
approval testing have been validated. They will still be available after the
UPL-U81 upgrade has been installed for type approval tests using the
UPL16 and the CRTC.
Using the UPL-U81, all acoustic tests in line with 3GPP TS 51.010 Release
99 are installed on the UPL16. These tests run on the Radio
Communication Tester CMU200. All tests required for type approval testing
are validated.

2 Preparation and Start of Application Software
Required Measuring Instruments and Accessories
The Audio Analyzer UPL16 with upgrade UPL-U81 and firmware 3.01 or higher
is required for the measurements.
The GSM mobile phone under test is driven by the Digital Radio
Communication Tester CMU200 via the RF interface. This tester simulates
a base station so that a call can be set up. The Radio Communication
Tester CMU200 must be equipped with the options CMU-B21 (versatile
signalling unit), CMU-B52 (speech codec) and the appropriate software
options for the GSM band used. The CMU200 must be equipped with
firmware 3.0 or higher.
Acoustic devices such as an artificial mouth, artificial ear and other
accessories are required for the measurements. The following equipment
from Brüel & Kjaer or G.R.A.S. is normally used (also HATS can be used):

or G.R.A.S. AA12
With the preamplifier set to 0 dB, the microphone power supply
B&K 2690A0S2 produces too much noise for measuring idle
noise and distortion. It is therefore advisable to set a gain of
20 dB. A low-noise power supply such as AA12 from G.R.A.S is
preferable.
C.4
E-1
Preparation and Start of Application Software
A cable with a BNC connector and a special small or angled banana plug is
required for connecting the artificial mouth, as the space between the
mouth connector and the test rack (B&K 4602B) is too small for common
banana plugs.
The transformer in the rear panel of the UPL16 is connected between the
generator output 1 of the Audio Analyzer UPL16 and the connector of the
artificial mouth. The transformer matches the impedance of the
loudspeaker in the artificial mouth to that of the UPL16 generator output.
Without this transformer, the available power is too low for driving the
artificial mouth.
Alternatively, a power amplifier preferably with a gain of approx. 0 dB can
be connected between generator output and mouth instead of the
transformer. In this case, the gain set must be kept absolutely stable after
calibration.
Together with the UPL-U81 upgrade, a cable with male (analyzer) and
female (generator) XLR connector is supplied for connection to the
"Speech" connector of the Radiommunication Tester CMU200.

Preparation and Start of Application Software
An external PC keyboard must also be connected to the UPL16 (large DIN
connector). A driver for country-specific keyboards can be defined in the
C:\UPL\USERKEYB.BAT file (see the UPL manual, section 2.15.4).
The BASIC programs required for automatic sequence control are on the
floppy supplied with the UPL-U81 upgrade option. The audio analyzer must
meet the following firmware requirements:
• UPL16 firmware version 3.01 or higher
• UPL-U81 upgrade (Mobile Phone Tests GSM Release 99) installed
• UPL16 configured with 64 kbyte program memory and 32 kbyte data
memory for automatic sequence control (using configuration tool UPLSET
setting 3).
Installing the Software
The application software is installed with the aid of the U81INST.BAT
installation program on the program floppy. The installation number of the
UPL-U81 upgrade (Mobile Phone Test GSM Release 99) must be known.
Caution: The software can only be installed on the specified Audio
Analyzer UPL16 with matching serial number.
½ Quit the measurement software by pressing the SYSTEM key on the
instrument or Ctrl + F9 on the keyboard.
½ Insert floppy
½ Select floppy disk drive (enter A:).
½ Call the installation program (enter U81INST).

Preparation and Start of Application Software
Program floppy contains the BASIC program R99_TST.BAS for measurements
on GSM mobile phones. It is loaded and started by entering:
•
LOAD"R99_TST"
•
RUN
The softkeys displayed at the bottom of the screen in the automatic
sequence control mode can be used instead.
Configuring the Application
"Default-Printer" is factory-set in the OPTION panel. This means that the
printer configuration does not depend on the setup, but that the printer used
last by the Audio Analyzer UPL16 remains configured. New settings need
not therefore be made by the user. It is useful to select the desired printout
with type, format, and scaling in manual mode before the program is
started. All subsequent printouts triggered with the hardcopy key will then
be printed with these settings.
IMPORTANT: Correct execution of the software cannot be guaranteed if
settings in the setup are changed.
Setup Conversion for Firmware Updates
For an update of the UPL16 firmware, the setups may have to be
converted. This is done automatically when the setup is loaded, but the
conversion delays the loading. To avoid the delay, the setups can be
converted before the application software is started:
•
at DOS level by calling the UPL16 conversion program:
DO_CONV \GSM
This converts all setups in the GSM directory.
IMPORTANT:
1078.2089.52
Please note that a previous firmware version can no longer be
used in the UPL16 after the conversion of setups.

4 Measurements
General
Special problems are encountered when measuring acoustic characteristics
caused by the coder and decoder algorithms of mobile phones. Vocoders are
used to attain the lowest possible data rate. In this case, not the actual
voice signals but only the filter and fundamental parameters required for
signal reconstruction are transmitted.
Purely sinusoidal tones normally used for the measurements cannot be
transmitted with such a system. In type-approval tests, the coder and
decoder are excluded from the measurement. A mobile phone required a
digital audio interface (DAI) for the transmission of audio signals with linear
PCM coding. The Audio Analyzer UPL16 is equipped with this DAI interface,
so that direct transmission of the test signals to and from a mobile phone
under test with DAI interface is possible.
Notes on Individual Measurements
The measurements to be performed are described below in the sequence
in which they are carried out.
Perform all measurements in an anechoic test chamber with sufficient
absorption against interfering sound. Since special distortion
measurements and the measurement of idle noise set high demands on
measurement conditions, the A-weighted noise in the test chamber must be
below 30 dB(A).
Measurements are started by pressing the corresponding softkey or
function key on the external keyboard. When the measurement is

Measurements
Sending Frequency Response
The sending frequency response is specified as the transmission ratio in dB
of the digital signal value at the DAI to the input noise pressure at the
artificial mouth.
The mobile phone under test is installed in the LRGP position (loudness
rating guard ring position to ITU-T P.76), and the speaker is sealed to the
artificial ear. Tones with a sound pressure of -4.7 dBPa are created with the
artificial mouth at the MRP (mouth reference point), and the digital value is
measured at the DAI and evaluated.
The sending frequency response must be within the tolerances specified
according to table 30.1 of 3GPP TS 51.010. The absolute sensitivity is not
yet taken into account.

The offset of the measured frequency response to the upper or lower limit
curve is calculated and then the whole trace is shifted by the mean value of
the maximum and minimum offset. Then another limit check is performed.
If the shifted curve is now within the limit lines, PASS is output, otherwise
FAIL is displayed. The limit check is only performed at each measured
frequency. It may happen that the trace slightly crosses a corner of the limit
curve although there are no limit violations.

Sending Loudness Rating
The sending loudness rating (SLR) takes into account the absolute
loudness in the transmit direction and weights the tones in compliance with
the normal sensitivity of the average human ear.
To this end the frequencies of bands 4 to 17 are evaluated according to
table 1 of ITU-T P.79.

The sensitivity at each frequency is defined as the ratio dBV/Pa referred to
the digital FS = 3.14 dBm0, and the sending loudness rating is calculated
according to formula 2.1 of ITU-T P.79.
According to 3GPP TS 51.010 the sending loudness rating should be
between 5 dB and 11 dB, with lower dB values corresponding to greater
loudness (5 dB = maximum loudness, 11 dB = minimum loudness). The
measured SLR is checked for compliance with these limits. In addition,
either PASS or FAIL is displayed.

Receiving Frequency Response
The receiving frequency response is specified as the transmission ratio in
dB of the sound pressure in the artificial ear to the digital signal value at the
DAI. The measured sound pressure is referred to the ear reference point
(ERP). For ear type 1, the measuring microphone is directly applied to the
ERP and a further correction is not required. For ear types 3.x, the
measuring microphone is applied to the drum reference point (DRP) which
is why any measured value has to be converted into the ERP by means of
correction factors.
The mobile phone under test is installed in the LRGP position (ITU-T P.76),
and the speaker is sealed to the artificial ear.
The signal is applied via the DAI, and the sound pressure in the artificial ear
is measured and evaluated.

Intermediate values are obtained when a straight line is drawn between the specified
values, and a logarithmic frequency scale and a linear dB scale are used.
The offset of the measured frequency response to the upper or lower limit
curve is calculated and the total curve shifted by the mean value of the
maximum and minimum offset. Another limit check is then performed. If the
shifted curve is within the limit lines, PASS is output, otherwise FAIL is
displayed. The limit check is only performed at each measured frequency. It
may happen that the trace slightly crosses a corner of the limit curve
although there are no limit violations.

Receiving Loudness Rating
There are two routines since the permissible limit values for the loudness
rating depend on the loudness set in the mobile phone under test.
REC_NOM checks the compliance with the rated loudness setting and
REC_MAX checks the maximum loudness.
The receiving loudness rating (RLR) takes into account the absolute
loudness in the receive direction and weights the tones in compliance with
the normal sensitivity of the average human ear.
To this end the frequencies (Hz) of bands 4 to 17 are evaluated according
to table 1 of ITU-T P.79.

The sensitivity at each frequency is specified as a ratio in dBPA/V referred
to the rated internal signal level, and the receiving loudness rating is
calculated according to formula 2.1 of ITU-T P.79.
The receiving loudness rating depends on the receiving loudness set on the
mobile phone under test and, according to 3GPP TS 51.010, should be
between -1 dB and +5 dB at a rated loudness setting, with lower dB values
corresponding to a higher loudness.
The RLR may not fall below -13 dB when maximum loudness is set on the
phone, i.e. the maximum receiving loudness may not exceed a certain
value to avoid damage to the human ear.
The RLR measured is checked for compliance with these limits. In addition
to the value measured, either PASS or FAIL is displayed.

Sidetone Masking Rating (STMR)
The sidetone path is the deliberate output of part of the signal picked up by
the microphone to the phone’s receiver. This is to create a natural hearing
impression for the person speaking on the phone as is encountered under
normal conditions that involve an acoustic path between mouth and ear.
The mobile phone under test is installed in the LRGP position (ITU-T P.76),
and the speaker is sealed to the artificial ear.
The STMR can only be measured with ear type 1 or ear type 3.2 Low
Leakage.
The artificial mouth generates tones with a sound pressure of -4.7 dBPa at
the MRP (mouth reference point), and the sound pressure is measured in
the artificial ear.
The suppression of the sidetone path is determined at each frequency
according to table 1 of ITU-T P.79, and the sidetone masking rating (STMR)
is calculated according to formula 2.1 of ITU-T P.79 with the weighting
factors of table 3 of ITU-T P.79 taken into account.
When the phone is set to the rated receiving loudness, the STMR should be
between 8 dB and 18 dB according to 3GPP TS 51.010.

Measurements
Listener Sidetone Rating (LSTR)
The listener sidetone rating defines the effect of interfering sound on the
voice quality. The microphone of the telephone not only picks up the wanted
voice but also any ambient noise.
To perform this measurement, a homogeneous noise field for simulating
the ambient noise has to be generated. This field is identical to that for
ambient noise rejection measurement.
This sound field must be generated by additional loudspeakers and noise
generators. To obtain a sufficiently homogeneous sound field, several
uncorrelated generators and loudspeakers are required. The use of 4 or 8
generators and loudspeakers is common practice. The noise sources have
to generate pink noise (1/f). The permissible error in the relevant thirdoctave bands must be smaller than ±3 dB, with the frequency response of
the loudspeakers used also being taken into account.
The LSTR measurement is divided into several measurements:

The sound field must be set to the required sound pressure level of
70 dB(A) using ADJUST.
To measure the sound field, the reference microphone is used (as for
mouth calibration). Fix the reference microphone to the mouth reference
point (MRP) using a suitable support. For the sound field measurement, all
other components such as artificial mouth or artificial ear must be removed.
After the ADJUST key has been pressed, a bargraph of the measured Aweighted sound pressure is displayed. It has to be set to a value of
70 ±1 dB. The tolerance limits are indicated by markers. Moreover, the
bargraph colour changes from green to yellow if the value is outside the
tolerance limits.
This adjustment of the sound field can practically be regarded as a
calibration and has to be repeated only if something changes in the sound
field generation. The long-term stability of the noise generators and
loudspeakers must of course be sufficient. Otherwise, this measurement
routine must be repeated as often as required.
The mobile phone under test is installed in the LRGP position (ITU-T P.76)
and the speaker is sealed to the artificial ear.
The setup is installed in a chamber with a calibrated noise field. The energy
distribution in this field is defined by 3GPP TS 51.010 and therefore known.
1078.2089.52

Measurements
The energy of the sound pressure in the artificial ear is measured by means
of third-octave analysis in the 14 bands with center frequencies from
200 Hz to 4000 Hz, and the suppression of the listener sidetone path is
determined for each band from the known rated values of the sound field.
The listener sidetone rating LSTR is then calculated with formula 8.4 of
ITU-T P.79 by taking into account the weighting factors of tables 6 and 4 of
ITU-T P.79.
The LSTR should not be less than 15 dB.

Measurements
Echo Loss
The echo loss measurement to 3GPP TS 51.010 with artificial voice usually
does not yield a PASS verdict. This problem was taken into account by the
latest specifications and a new version of the echo loss measurement was
created. This version is nominally validated only for GSM Release 4 or
3GPP mobiles, but contrary to the previous version provides accurate
measurement results. The implementation of the echo loss measurement
conforms thus not just to Release 99, but already to Release 4.
The echo loss is the attenuation between the voice coder input and the
voice decoder output (gain of voice coder + decoder = 1). Normally the
echo loss is caused by internal acoustic coupling between the telephone
receiver and the microphone. Since the echo considerably reduces the
sound transmission quality, it may not exceed a certain value.
The mobile phone under test is placed in the anechoic chamber at no
specific position (former releases used the LRGP position!).
A modulated multitone signal to ITU-T P.501 is generated as a test signal
and applied to the voice coder. First, the spectral energy distribution of the
generated signal is measured in the third-octave bands from 200 Hz to
4 kHz. Then, the spectral distribution in the output signal of the voice
decoder is measured. The echo loss is calculated from the differences of
the individual bands according to ITU-T G.122. As an option, the mobile
phone under test can be fed for approx. 10 s with the male and female
version of artificial voice according to ITU-T P.50 prior to this measurement.
This training sequence is to facilitate optimization for potential echo
cancellers.The actual gain of the voice coder and decoder must also be
considered in the result. This value is available in the CMU after calibration
of the coder.
3GPP TS 51.010 specifies an echo loss of at least 46 dB which can be
achieved by mobile phones using good echo cancellers. Since the
microphone also picks up any side noise and treats it like an echo, it is
essential that the test chamber is shielded against external noise.

Measurements
Stability Margin
The stability margin is measured to test the susceptibility of the phone to
acoustic feedback and instability.
For the test, the telephone is placed on an even, hard board with the
receiver and microphone pointing downwards.
A loop is closed in the UPL16 between the receiving and the voice channel
and an overall gain of 6 dB is set. The gain of the coder is automatically
taken into account (see also echo loss).
To activate the loop, a noise signal of -10 dBm0 in line with ITU-T O.131 is
applied for 1 s and then switched off, with the loop remaining closed.
The test person has to listen whether resonances or oscillations are
produced. If there are no oscillations, the minimum requirements to 3GPP
TS 51.010 for a stability margin of 6 dB are complied with. This routine does
not yield any measurement result!
Sending Distortion
The S/N ratio in the transmit path is measured as a function of the sound
level.
The mobile phone under test is installed in the LRGP position (ITU-T P.76),
and the speaker is sealed to the artificial ear.
The test signal is generated with the artificial mouth at the MRP (mouth
reference point), and the SINAD value of the received signal is measured at
the DAI.
The acoustic reference level (ARL) is defined as the sound pressure which
creates a signal level of -10 dBm0 in the transmit channel. An automatic
routine varies the sound pressure at the artificial mouth until the desired
level is attained. This value is then used as a reference for determining the
SINAD value versus level.
The SINAD value is measured at sound pressures between -35 dB and
+10 dB relative to the acoustic reference level (ARL) and compared with the
limit lines specified in table 30.3 of 3GPP TS 51.010.

Sidetone Distortion
The cubic distortion of the sidetone signal coupled between microphone

The test signal is generated with the artificial mouth at the MRP (mouth
reference point) and the sidetone signal distortion in the artificial ear is
measured at the signal frequencies 315 Hz, 500 Hz and 1000 Hz.
The distortion of the sidetone signal must be less than 10 %.

Out of Band Sending
Signal components in the voice band up to 4 kHz are measured. They can
be generated by acoustic triggering of the mobile phone with signals in the
4.6 kHz to 7.5 kHz range and may be due to inadequate filtering or
unwanted mixer products.
The mobile phone under test is installed in the LRGP position (ITU-T P.76)
and the speaker is sealed to the artificial ear.
The test signal is generated with the artificial mouth at the MRP (mouth
reference point), and the received signal is band-filtered and measured at
the DAI.
The products in the frequency range up to 4 kHz generated by out-of-band
signals must be below the limit line to 3GPP TS 51.010, table 30.5.

The test signal is fed via the DAI, and the spectrum of the acoustic signal in
the artificial ear in the frequency range above 4 kHz is measured.

Idle Channel Noise Sending
The idle noise signal at the DAI is measured with the telephone set up in a
quiet environment (< 30 dB(A)).
The mobile phone under test is installed in the LRGP position (ITU-T P.76),
and the speaker is sealed to the artificial ear.
The digital signal at the DAI is measured, psophometrically weighted
according to ITU-T G.223 and calculated at the internal level in dBm0p.
The idle noise level should not exceed -64 dBm0p.
Fig. 15 Idle noise sending
Idle Channel Noise Receiving
The sound pressure in the artificial ear is measured with the phone set up in
a quiet environment.
The mobile phone under test is installed in the LRGP position (ITU-T P.76),
and the speaker is sealed to the artificial ear.
The sound pressure in the artificial ear is measured with A-weighting on.
With rated loudness set on the mobile phone, the sound pressure should
not exceed -57 dBPa(A).
At maximum receiving loudness, the sound pressure should not exceed 54 dBPa(A).
This measurement makes high demands on the sound insulation of the test
chamber and the S/N ratio of the measuring microphone including
preamplifier in the artificial ear. A comparison measurement with the mobile
phone under test switched off or without a DUT shows the measurement
reserves of the test equipment. Due to the inherent noise of the Audio
Analyzer UPL16, measurements can be made to about -80 dBPa(A) at 0 dB
microphone gain, and even to lower values when a higher microphone gain
is set.

Ambient Noise Rejection
The ambient noise rejection measurement is not precisely defined for
Release 99 in 3GPP TS 51.010. This problem was taken into account by
the latest specifications and a new version of the ambient noise rejection
measurement was created. This version is nominally validated only for
GSM Release 4 or 3GPP mobiles, but unlike the older version provides
accurate measurement results. The implementation of the ambient noise
rejection measurement thus conforms not to Release 99, but already to
Release 4.
Ambient noise rejection (ANR) describes the weighted ratio of voice signal
transmission to ambient noise. An ANR value >0 dB means that voice as
the useful signal is transmitted more loudly than any ambient noise. The
minimum requirement to 3GPP TS 51.010 is ANR > -3 dB. A value >= 3 dB
should at least be attained.
To perform this measurement, a homogeneous noise field for simulating
the ambient noise has to be generated. The same noise field is also used to
measure the LSTR.
This sound field must be generated by additional loudspeakers and noise
generators. In order to obtain a sufficiently homogeneous sound field,
several uncorrelated generators and loudspeakers are required. The use of
4 or 8 generators and loudspeakers is common practice. The noise sources
have to generate pink noise (1/f). The permissible error in the relevant thirdoctave bands must be smaller than ±3 dB with the frequency response of
the loudspeakers used also being taken into account.
The measurement of ambient noise rejection is divided into several single
measurements.

The sound field must be set to the required sound pressure level of
70 dB(A) using ADJUST.
To measure the sound field, the reference microphone is used (as for
mouth calibration). Fix the reference microphone to the mouth reference
point (MRP) using a suitable support. For the sound field measurement, all
other components such as artificial mouth or artificial ear must be removed.
After the ADJUST key has been pressed, a bargraph of the measured
A-weighted sound pressure is displayed. It has to be set to a value of
70 ±1 dB. The tolerance limits are indicated by markers. Moreover, the
bargraph colour changes from green to yellow if the value is outside the
tolerance limits.
After the CONT key has been pressed, the spectral distribution is measured
automatically with an automatic check for compliance with the stipulated
absolute level and the pink distribution. If a 1/f-weighted noise density (pink
noise) is precisely complied with, a third-octave analysis yields identical
amplitudes in each third-octave band. The tolerance of ±3 dB is complied
with if the difference between the largest and smallest band measured is
less than 6 dB. If this difference is larger, a warning will be output on the
screen. A warning will also be output on the screen if the absolute sound
pressure is outside the permissible tolerance.
This adjustment and testing of the sound field can practically be
regarded as a calibration and has to be repeated only if something
changes in the sound field generation. The long-term stability of the
noise generators and loudspeakers must of course be sufficient.
Otherwise, this measurement routine must be repeated as often as
required.

Measurements
For the actual measurement of ANR, the artificial mouth and the artificial
ear must be installed again. The MRP must be installed at the same
position as the reference microphone before.
The mobile phone under test is installed in the LRGP position (ITU-T P.76),
and the speaker is sealed to the artificial ear.
Set up a call to the CMU and set the bit stream to "Handset Low".
Press the START key to start the measurement of the room noise
sensitivity.
After completion of the measurement, the request to switch off the noise
field will be displayed on the screen. If this is confirmed, the speech sending
sensitivity will be measured automatically and the ANR value calculated
afterwards.
The ANR values must exceed -3 dB.

Calibration Routines
5 Calibration Routines
All calibration data is stored on the UPL16 hard disk and is automatically
available at every restart. The calibration values for the different ear types
are stored independently from each other and other options. The calibration
values for the artificial mouth are identical to the values for the older MAIN
and MAIN32 programs.
Calibration of Artificial Ear
Before a mobile phone can be tested, the absolute sensitivity of the
microphone in the artificial ear must determined using a sound level
calibrator such as the Brüel & Kjaer 4231 with a sound pressure level of
94 dBSPL or a sound pressure of 1 Pa at 1 kHz.
Note:
The calibration values of the different ear types are stored separately. So, a
calibration need not be performed after a change of the ear type if the
physically identical ear has been calibrated before.
Calibration of Ear Type 1
½ Switch off the microphone power supply.
Note:
The 200 V polarization voltage of the microphone may cause
a slight electric shock. The current is harmless but the
microphone preamplifier may be damaged
½ Remove the microphone from the artificial ear.
½ Screw back the microphone capsule and switch on the operating voltage.
½ Insert the microphone fully into the adapter of the sound level calibrator and
switch on the calibrator.
Note:
After inserting the microphone wait at least 10 s to allow for
static pressure compensation.
½ Select the CALIBRATION level using the F12 key.

microphone (recommended value), the sensitivity displayed must be about
10 times the value in the calibration certificate of the microphone capsule
(typical value for microphone capsule 4134 and artificial ear 4185 is approx.
12 mV/Pa, display = 120 mV/Pa). If the voltage measured is below 3 mV,
an error message is displayed. Possible error sources are, for example, a
switched off microphone power supply or a disabled calibrator. In this case,
the program requests the test to be repeated. After switching on the

Calibration of Artificial Mouth
The calibration of the artificial mouth does not depend on the ear type
used. A recalibration is therefore not required when the ear type is
changed.
Before a mobile phone can be tested, the absolute sensitivity and frequency
response of the artificial mouth have to be measured and corrected with the
aid of a previously calibrated pressure-field measuring microphone. The
measuring microphone removed from artificial ear type 1 can be used for
this purpose or an additional microphone capsule is screwed to the
microphone preamplifier. The measuring microphone is used as a
reference for determining the frequency response of the mouth. The
frequency response of the microphone can be ignored in the test frequency
range (100 Hz to 8 kHz) (see also calibration certificate of microphone
capsule).
Since interfering sound falsifies the corrections, the artificial mouth must be
calibrated in a sound-proof test chamber.
First of all, the measuring microphone has to be calibrated.
½
Insert the measuring microphone fully into the adapter of the sound level
calibrator and switch on the calibrator.
Note: After inserting the microphone into the calibrator wait at least

The sound pressure generated at the MRP is set to exactly -4.7 dBPa in
an automatic measurement routine at 1 kHz. The generator voltage
required is stored in a nonvolatile memory and used as a reference for
all subsequent settings with the artificial mouth. If the sound pressure
cannot be adjusted to -4.7 dBPa, an error message is displayed with a
request to check the connection of the artificial mouth and to repeat the
measurement. A possible error source is that the transformer supplied is
not connected between the generator and the artificial mouth.
The uncorrected frequency response of the artificial mouth is measured
and displayed. Next, the frequency response is measured with the
inverse frequency response correction automatically selected in the
generator (equalization). Residual errors caused by non-linearities of the
speaker in the mouth are measured and taken into account in the final
equalization file as fine correction.
To verify the results, the absolute sound pressure versus frequency is
measured at a sound pressure of -4.7 dBPa (reference value for most of
the measurements). The absolute sound pressure at each frequency
must be within a tolerance band of -4.7 dBPa ±0.2 dB. Correct
calibration without interfering sound yields an almost straight line in the
middle between the two limit lines.

1078.2089.52

Processing of Measurement Results
Since the TRC, EXP, ABS and PCX files are consecutively numbered, it is
useful to copy the files of a measurement sequence, for example, and to
save them under a new name. In this case, the original files can be deleted.
Thus results can be identified more easily and a mix up between them
avoided.
To this end a DOS shell can be called after termination of the test program
(e.g. with key F5) by entering the command SHELL <RETURN>. The files
can be copied and saved under another name (as standard in the
C:\GSM\RESULTS directory) using common DOS commands. Entering
EXIT <RETURN> brings back BASIC without the program being deleted.
The program can be restarted immediately by entering RUN.
The screen content can be output to a printer by pressing the HARDCOPY
key.
Printer type and desired settings are not selected by the program but the
printer selected last and set in the UPL16 manual mode will be chosen. For
this reason, the printer, scaling and format must be manually set once in
the OPTION panel of the UPL16 prior to the measurement. It is
recommended to select a LOW or MEDIUM resolution and integer scale
factors for the printer output. If fractional scale factors (especially values
<1) are used, the pixel values are interpolated and the print quality
is reduced.
It may be useful to first print a test copy to check the print quality. Contrary
to manual operation, no COMMENT line is printed in this case and the
program automatically sends a FORM FEED after each print to throw out
the hardcopy.
All the purely numerical values are automatically added to the
RES_99.LOGRES_99.LOG result file after each measurement. Thus all
numeric measurement results can be called again and evaluated after a
measurement sequence has been performed.
As with TRC and PCX files, it may be useful to copy the RES_99.LOG file
after a measurement sequence and to save it under a new name.
Afterwards the RES_99.LOG file can be deleted. Thus results can be
identified more easily and a mix up between them avoided. To this end, a
DOS shell can be called after termination of the test program (e.g. with key
F5) by entering the command SHELL <RETURN>. The file RES_99.LOG
can be copied and saved under another name using common DOS
commands.
Entering EXIT <RETURN> brings back BASIC without the program being
deleted. The program can be immediately restarted with RUN.
