Audio analysis today and tomorrow
Analog and digital
Audio signal processing without digital
technology is no longer conceivable. Yet,
analog technology is still present and
constantly being improved. State-of-theart measuring instruments must therefore be able to handle both analog and
digital signal processing.
The Audio Analyzer R&S UPL performs virtually every type of analog measurement:
frequency response measurements; externally controlled sweeps with reference
traces; determination of 3rd order difference frequency distortion; or spectral display of demodulated wow and flutter
signals. In contrast to many other audio
analyzers, the R&S UPL can perform real
dual-channel measurements in the audiofrequency range, i.e. there is no need for
2
Audio Analyzer R&S UPL
switchover between two inputs and this
type of measurement is not limited to a
few special cases.
The generator is equally versatile:
it supplies any conceivable signal whether
sinewave, noise signals, or multi-sinewave
signals comprising up to 7400 frequencies.
In addition, the R&S UPL features excellent technical data: analog sinewave generation with harmonics of typ. −120 dB;
spectrum displays with a noise floor
below −140 dB for analog and −160 dB
for digital interfaces; and FFT with a maximum frequency resolution of 0.05 Hz.
The R&S UPL provides signal monitoring
via loudspeaker, jitter measurements on
digital audio signals, resynchronization of
jittered digital audio signals by means of a
jitter-free clock signal, and much more.
Superior analysis concept
The R&S UPL performs all measurements
using digital signal processing. Analog signals to be tested undergo elaborate preprocessing before they are digitized and
measured by means of digital routines. For
example, in THD measurements, the fundamental is attenuated by means of a
notch filter and the residual signal amplified by 30 dB before it is digitized. In this
way, the dynamic range can be extended
beyond that offered by the internal 20-bit
converter. This provides sufficient margin
for measuring converters of the future,
which will be more advanced than those
with present-day technology (see graph on
the right). This concept ensures performance and flexibility by far superior to
instruments providing purely analog or
digital measurements.
It also offers many other advantages over
analog technology alone:
◆ The test routines for analog and digital interfaces are identical. This allows, for example, the direct comparison of IMD measurements made
ahead of and after a converter.
Performance
Purely
digital
measurements
◆ In intermodulation measurements,
spurious components are measured
selectively for all frequencies in accordance with the mathematical formulae of the applicable test standards.
This procedure prevents the inclusion
of adjacent components in the measurements, which is usually inevitable
with analog test methods.

A future-proof investment
No one can accurately predict the effects
that future developments in digital technology will have on the audio world and
the resulting test requirements. Yet this is
not a problem for the Audio Analyzer R&S
UPL. Since all test functions are implemented digitally, the R&S UPL can be
adapted to changing requirements by simply loading the necessary software – and
this also applies to analog interfaces.
One more benefit: Rohde & Schwarz is the
only manufacturer to equip its audio analyzers with 32-bit floating-point signal processors throughout, thus offering plenty of
capacity beyond the limits of today’s common 24-bit technology.
A competent partner
The intelligent combination of analog and digital measurement
techniques paves the way for future applications.
◆ All test functions are available on the
analog and the digital interfaces. This
makes it possible to perform measurements at any point along a common
analog and digital transmission path,
the only way to ensure efficient and
complete testing.
◆ The filters are also implemented digitally, yielding a more or less infinite
number of them – and this also holds
true for measurements on analog interfaces. To loop a new filter into the
test path, you merely have to choose
the type of filter (e.g. highpass), cutoff frequency and attenuation.
Certified Environmental System
◆ Measurement speed is usually higher
than with analog techniques since
digital test routines can adapt their
speed to the input frequency.
◆ And last but not least: Operation is
the same for the analog and the digital interfaces – a feature that should
not be underestimated.
Certified Quality System
The name Rohde & Schwarz stands for
excellent quality – thousands of audio analyzers are already in the hands of satisfied
customers and have been operating successfully for many years. Following in the
footsteps of the exclusively analog R&S
UPA and R&S UPD, which still hold the top
position in today’s audio measurement
technology, the Audio Analyzer R&S UPL
was developed to complement the product
line.
As a competent partner we will be happy
to advise you on the optimum use of our
instruments. Our representatives are
available all over the world, and our customer support center and application
engineers in Munich can help you find
the right solution to your measurement
tasks. In addition, a wealth of suggestions and solutions can be found in our
application notes and software.
As part of our emphasis on quality,
Rohde & Schwarz instruments are certified in compliance with ISO 9001 and ISO
14001.

Audio Analyzer R&S UPL
The generators of the R&S UPL supply an
extremely wide variety of analog and –
when the options R&S UPL-B2 or R&S
UPL-B29 are used – digital test signals:
◆ Sinewaves
For level and harmonic distortion measurements. The signal can be applied
to an equalizer with selectable nominal
frequency response, e.g. for compensating the frequency response of the
test assembly.
◆ Two-tone signal
For modulation distortion analysis.
Various amplitude ratios can be selected and the frequencies are continuously adjustable.
◆ Difference tone signal
For intermodulation measurements
with continuous setting of both frequencies.
◆ Multitone signal
Can comprise up to 17 sinewaves of
any frequency and with the same or
different amplitude; setting the phase
is also possible with the R&S UPL-B6.
◆ Sine burst signal
With adjustable interval and on-time
as well as programmable low level,
e.g. for testing AGCs.
◆ Sine2 burst
Also with adjustable interval and ontime, e.g. for testing rms rectifier circuits.
◆ Special multitone signal
Can comprise up to 7400 frequencies
with selectable amplitude distribution. The frequency spacing can be
linked to the resolution used for the
fast Fourier transform, thus enabling
rapid and precise single-shot measurements of the frequency response
of a DUT.
◆ Noise
With a variety of probability distributions, e.g. for acoustic measurements;
setting of crest factor with the R&S
UPL-B6.
◆ Arbitrary waveforms
For generating any voltage curve of
up to 16k points. Test signals can be
output in different file formats, e.g.
voice and music signals stored as WAV
files.
◆ Two-channel sinewave signals
For the two digital output channels
when the UPL-B6 is used.
◆ AM and FM
For sinewave signals.
◆ DC
Also with sweep function.
Signals can be generated with an offset.
Moreover, digital audio signals can be
dithered with adjustable level and
selectable amplitude distribution.
Versatile test functions
The R&S UPL offers a wealth of measurement functions both for analog and –
when the option R&S UPL-B2/-B29 is used
– for digital interfaces.
◆ Level or S/N
This function includes rms, peak or
quasi-peak weighting and ensures
high measurement speeds due to automatic adaptation of integration time
to the input signal.
◆ Selective level
The center frequency of the bandpass
filter can be swept or coupled to the
generator frequency, to the frequencies
of a multitone signal (e.g. for fast frequency response measurements) or to
the input signal.
◆ SINAD or THD+N
The sum of all harmonics and noise is
measured (Fig. 1).
◆ Total harmonic distortion (THD)
Individual harmonics, all harmonics or
any combination of harmonics can be
measured (Fig. 2).
◆ Modulation distortion
This measurement complies with
DIN-IEC 268-3. 2nd and 3rd order intermodulation is measured.
◆ Difference Frequency Distortion
This intermodulation measurement
uses the difference tone method. 2nd
and 3rd order intermodulation is measured.
◆ Wow and flutter
This measurement uses the DIN IEC,
NAB, JIS or 2-sigma method in accordance with DIN IEC and also displays
the demodulated-signal spectrum.
◆ DC voltage
◆ Frequency, phase and group delay
◆ Polarity
Signal paths are checked for
reversed polarity.
◆ Crosstalk
◆ Waveform function
This function is used to represent the
test signal in the time domain (Fig. 3).
Waveforms can be smoothed by interpolation. Slow sequences can be displayed compressed, e.g. for analyzing
the transient response of compander
or AGC circuits (Fig. 4).
◆ Extended Analysis Functions
R&S UPL-B6
The coherence and transfer functions determine the transfer characteristics of complex test signals;
third octave analysis is used mainly
for acoustic measurements; rub &
buzz is measured in loudspeaker production.
Tests on hi-fi components call for increasingly complex measurement techniques. Results
obtained in the test lab must be verified in production, which usually requires economical solutions for handling large batches rather than the use of all available functions. The R&S UPL is an
ideal choice for this task. It optimally complements its “bigger brother“,the Audio Analyzer R&S
UPD, which is mainly employed in development. The two units share the exact same IEC/IEEE bus
commands, which means they have the same operating concept and can be used together.
Audio Analyzer R&S UPL

Fig. 5: FFT spectrum of two-tone signal shown on full screen.
Spectrum analysis
A variety of sweep functions
With its FFT analyzer, the R&S UPL is also
capable of spectrum analysis. The number
of samples for fast Fourier transform can
be selected between 256 and 16k in binary
steps (Fig. 5). A special feature is zoom FFT.
The signal to be measured is digitally preprocessed to increase the frequency resolution by a factor of 2 to 128 over a selectable range. In this way, a maximum resolution of 0.05 Hz is attained. This is not
merely a scale expansion, the measurement is actually performed at a higher resolution (Fig. 6).
For continuous variation of the test
signals, the R&S UPL offers amplitude
and frequency sweeps; in the case of
bursts, it is also possible to perform
sweeps of intervals and on-time. Sweeps
are defined either by means of a table or
via parameters such as start value, number of steps, linear/ log stepping or time
interval. It is also possible to sweep two
variables simultaneously.
Programmable filters
Fig. 6: With the zoom FFT function, sidebands spaced only a
few hertz from the signal can be displayed.
Fig. 7: Filters can be defined by entering just a few
parameters.
Fig. 8: Tolerance curves enable fast go/no-go tests.
6
Audio Analyzer R&S UPL
The filters of the R&S UPL are softwareimplemented, allowing the user to define
any number of filters. The most common
weighting filters are provided as standard. Additional filters can be programmed in a few seconds by entering
the type (lowpass, highpass, bandpass,
bandstop, notch, third octave or octave),
frequency and attenuation (Fig. 7). The
instrument’s open architecture reveals its
strength particularly where special
requirements have to be met: special filters can be implemented by using commercial filter design programs. The data is
transferred to the R&S UPL and the
required filter is looped into the signal
path.
*) For more information, refer to data sheet
PD 0757.6985, Multichannel audio
measurements on surround sound decoders.
If external signals are applied during
measurement, they can be used for analyzer sweeps (external sweeps). Many different start conditions can be set, allowing measurements to be triggered by a
variety of events. Even if the DUT has an
unknown or unstable transient response,
the settling function will yield stable
results.
Multichannel measurements
with Audio Switcher R&S UPZ
The Audio Switcher R&S UPZ is used
either to measure surround sound decoders or in production if several DUTs/channels have to be cabled. It is directly connected to the Audio Analyzer R&S UPL
and panel-controlled via an RS-232-C
interface. The 8-channel R&S UPZ is available as an input and output model and
can be cascaded to up to 128 channels. *)
The Audio Switcher R&S UPZ can be controlled
directly from the R&S UPL.
◆ Built-in hard disk and disk drive
◆ Connectors for keyboard, mouse,
monitor, printer and plotter
◆ Centronics interface for connecting
printer or network
◆ Drivers for commercial printers supplied as standard
◆ Remote control via IEC/IEEE bus or
RS-232-C interface
◆ Postprocessing of results directly in
the R&S UPL using standard software
◆ All results available in the common
data formats, making it easy to import
graphics into documents, for example
◆ Easy loading of function and software
extensions via floppy disk
◆ Automatic test sequences and measurement programs with universal sequence controller, plus easy generation of programs with built-in program
generator
The strengths of the R&S
UPL become evident
especially in mobile use.
The unit is compact and
lightweight and requires
no additional equipment.
Results are stored in the
built-in PC and thus available for later use. Routine
measurements can be
repeated easily using
stored instrument
settings.
Everything in one package
The Audio Analyzer R&S UPL is a compact
unit with an integrated controller. It avoids
the disadvantages of external PC control
found in other audio analyzers. The instrument is easy to transport as it requires no
external equipment such as keyboard,
monitor or other PC peripherals.
With audio analyzers controlled from an
external PC, interference may be radiated
from the PC, the monitor or interface connections, which distorts measurement
results. Not so with the R&S UPL: the
instrument has specified EMC characteristics which also include the internal PC. In
contrast to conventional PCs, the R&S UPL
provides elaborate screening features
such as magnetically shielded power
transformers and a coated filter pane in
front of the display.

Audio Analyzer R&S UPL
Analog interfaces
◆ Balanced inputs with high commonmode rejection and various types of
impedance commonly used in the studio. Measurements can be made on
lines with phantom feed.
◆ Balanced outputs, floating (e.g. to
prevent hum loops).
◆ The generator outputs can be internally connected to the analyzer inputs
so that different types of measurement can be performed without
changing the cabling.
Digital audio interfaces (options
R&S UPL-B2 and R&S UPL-B29)
◆ Balanced (XLR), unbalanced (BNC) and
optical (TOSLINK) inputs and outputs
for connecting consumer electronics
and professional studio equipment are
provided.
◆ The levels of the balanced and unbalanced outputs are adjustable so that
the sensitivity of digital audio inputs
can be determined.
◆ The format of the generated channel
status data may be professional or
consumer regardless of the selected
interface.
◆ A reference (XLR) and a synchronization (BNC) input provided on the rear
panel allow both the analyzer and the
generator to be synchronized to the
digital audio reference signal (DARS)
in line with AES 11; in addition the
generator can be synchronized to
wordclock, video sync signals (PAL/
SECAM/NTSC) and 1024 kHz reference clocks.
◆ Both generator and analyzer can be
operated at clock rates of 35 kHz to
106 kHz. The clock signal can also be
produced internally by the generator.
◆ The clock rates of the analyzer and
generator are independent of each
other. This allows measurements on
sample rate converters.
◆ The word length can be selected independently for generator and analyzer
between 8 and 24 bits.
Improvement of audio quality of sound cards and multimedia equipment – a task for the R&S UPL.
Digital protocol analysis and
generation (option R&S UPL-B21)
This software option extends the functions
of options R&S UPL-B2 and R&S UPL-B29
by an in-depth analysis and generation of
additional digital data:
◆ Analysis of channel status and user
data. The data is output in binary
form, as hexadecimal numbers, or as
ASCII characters, or, in the case of
channel status data, it is evaluated in
the professional or consumer format
in line with AES 3 or IEC 958 (Fig. 12).
◆ Generation of channel status data,
user data and validity bits. Channel
status data can be entered in binary
form or via panel in line with AES 3 or
IEC 958 using the professional or consumer format.
◆ Any bits can be combined under a
symbolic name. In this way, data input and representation can easily be
adapted to customer requirements.
◆ Simultaneous measurement of clock
rate and display of interface errors
(such as parity error).
Jitter and Interface Tests
(option R&S UPL-B22)
The physical parameters of digital audio
interfaces can be evaluated with this
option. The R&S UPL-B22 extends the
functions of options R&S UPL-B2 and R&S
UPL-B29.
Signal analysis:
◆ Measurement of jitter amplitude and
display of jitter signal in the frequency
and time domain (Figs 9 and 10).
◆ The R&S UPL generates bit- or wordsynchronous sync signals that allow
the accurate display of digital audio
signals on an oscilloscope (preamble,
eye pattern, signal symmetry, superimposed noise, etc).
◆ Measurement of input pulse amplitude and sampling frequency.
◆ Measurement of phase difference between audio and reference input signal.
◆ Measurement of time difference
between output and input signal. This
allows delay times of equalizers, audio mixers, etc to be measured.
◆ Analysis of common-mode signal of
balanced input (frequency, amplitude,
spectrum).
Digital components of various data formats and clock rates are the stock-in-trade of professional users, who need a measuring instrument offering top performance on all interfaces with high
accuracy and over a wide dynamic range. Operation is identical for analog and digital interfaces, which enhances operator convenience. Fast fault diagnosis is possible by means of stored
test routines, allowing the elimination of problems immediately before transmission.
Signal generation:
◆ The clock of the output signal can be
“jittered“ by superimposing a sinewave or noise signal of variable amplitude.
◆ When generating digital audio data –
with option R&S UPL-B1 installed –
jitter and common-mode interference
can be added to the data stream.
◆ An input signal with jitter can be output jitter-free.
◆ A common-mode signal can be
superimposed on the balanced output
signal.
◆ Long cables can be simulated by
means of a switchable cable simulator.
◆ The phase shift between the digital
audio output and the reference output can be varied.
Generation of coded audio signals
(option R&S UPL-B23)
With this option, the Audio Analyzer R&S
UPL is able to generate AC-3-coded test
signals (other data formats soon available) directly with the integrated generator, e.g. to measure surround sound
decoders.
The number of channels, frequency or
level sweep, start and stop frequency/
level as well as the number of sweep
points can be set, thus allowing flexible
test sequence combinations.
The measurements are automatically synchronized between generator and analyzer.
The R&S UPL-B23 requires options R&S
UPL-B2 or R&S UPL-B29. For more information refer to data sheet PD 0757.6985,
Multichannel audio measurements on
surround sound decoders.

Designed for convenience
Efficient online help
The R&S UPL offers a variety of help features:
HELP function
HELP information in German or English can
be called up for each input field.
SHOW I/O key
If results cannot be displayed, e.g.
because an input signal is either missing or
incorrect, information on possible causes
will appear upon pressing SHOW I/O.
Moreover, the input and output configuration will be displayed.
Info boxes
These highlighted boxes indicate any
incorrect settings.
Online help
The permissible range of values is indicated for each menu item requiring the
entry of a numeric value. This range takes
into account any limitations resulting from
related parameters, e.g. the sample rate in
the case of measurements on digital interfaces.
Protection against invalid entries
The R&S UPL will not accept entries outside the permissible range. An alarm
tone will be issued and the value
changed to the permissible minimum or
maximum value.

Audio Analyzer R&S UPL
A wealth of functions – yet easy to operate
◆ Related functions and settings are
combined in panels that can be called
up at a keystroke. Up to three panels
can be displayed at a time.
◆ The operator is not burdened with unnecessary information. Only the parameters and settings needed for a
specific application are displayed –
the others are available in the background. (For example, the sweep parameters are transferred to the generator panel and displayed only when
the sweep function is activated.)
◆ Fast access to frequently used instrument setups and a comprehensive library of standard measurements
make the instrument easy to learn.
◆ Straightforward data entry: the user
simply needs to open a menu and
make an entry or selection.
◆ Continuously updated status information on generator, analyzer and
sweep.
◆ Quick operating sequences through the
use of softkeys, e.g. for graphical representations.
◆ The user can choose between operation via mouse, external keyboard or
front panel. This choice is important
since the working space required by a
mouse is not always available.
◆ Short learning time due to an easy-tounderstand operating concept that
treats analog and digital measurements in the same manner.
Results at a glance
◆ Realtime display of results for one or
both channels and several test functions.
◆ Simultaneous display of frequency
and phase.
◆ With graphics, results can be read off
with vertical and horizontal cursors.
Tolerance curves or stored results can
be added for comparison.
◆ Sets of traces can be displayed,
stored and evaluated for both channels.
◆ Graphics options include traces and
bargraphs, spectrum display, and
three-dimensional waterfalls.
In many cases only a few parameters
need to be modified after a measurement
sequence has been started. Therefore,
entry lines can be selected from the input
panels for the generator, analyzer, etc, by
means of a checkmark. They are then
transferred to a status panel. The status
panel thus gives a summary of parameters for a measurement routine, which
offers the following advantages:
◆ Instrument settings can be displayed
together with graphical and numerical results.
◆ All important information can be
printed on a single hardcopy.
◆ Instrument settings can be modified
quickly without changing panels as
the R&S UPL can also be operated
from the status panel.
Audio Analyzer R&S UPL

Fast and efficient
High measurement speed
In designing the Audio Analyzer R&S
UPL, particular emphasis was placed on
optimizing the measurement speed of
the test system as a whole:
◆ All operations involving extensive
number crunching are carried out by
digital signal processors. The PC is
merely used for controlling the unit
and displaying results.
◆ The R&S UPL can perform even
complex test functions simultaneously on both channels. This feature alone reduces the time for stereo
measurements by 50% compared to
most analyzers available on the
market.
◆ The digital test routines adapt their
speed optimally to the input frequency. This enhances measurement speed especially in the case of
frequency sweeps.
◆ The R&S UPL performs harmonic
distortion and IMD measurements
using patented, digital test procedures that combine high accuracy
with high measurement speed.
◆ Digital signal processing reduces
setting and transient times achievable with purely analog
instruments. These times are also
taken into account in the test routines, yielding stable measurements
without the need for activating settling functions (these are
understood to be repeated measurements until results are within a
tolerance band).
12
Audio Analyzer R&S UPL
◆ The user interface was tailored to the
requirements of a test environment,
not an office one.
◆ Display windows not needed can be
switched off, which also reduces the
processing time. When all displays are
switched off and results are output via
the IEC/IEEE bus, more than 100 level
measurements per second can be performed.
Use in production
Instruments to be used in production
tests must satisfy a variety of requirements:
◆ High measurement speed is vital for
achieving a high production throughput. By making appropriate use of the
instrument functions, go/no-go decisions can already be made in the audio analyzer, thus reducing the run
time of a DUT (Fig. 8).
◆ Two-channel measurements allow the
simultaneous and thus time-saving
determination of input and output
characteristics.
◆ The use of FFT analysis provides a decisive advantage especially in the
case of frequency response measurements, which are particularly timecritical (example: approx. 900 frequency values in 150 ms).
◆ Long calibration intervals, resulting
from the extensive use of digital
circuits, make for high availability of
the instrument.
◆ The R&S UPL66 model is specially tailored to the requirements of production. It comes without a display and
keypad, thus holding down costs. Yet
the unit can be operated manually by
connecting a PC keyboard and a VGA
monitor, enabling fast fault localization in the event of production problems.
The R&S UPL66 – special model for use in test
systems, with the full flexibility of the standard
model.
High measurement speed, two-channel
measurements and remote-control capability via the IEC/IEEE bus are a must in
production systems. The long calibration
intervals of the R&S UPL make for high
availability and reduce costs.
◆ Remote-control capability via the IEC/
IEEE bus is a must in large-scale production systems. In the design of the
Audio Analyzer R&S UPL, special importance was attached to data transfer via the IEC/IEEE bus. The logging
mode can be used to speed up the
generation of control programs for the
IEC/IEEE bus. With the program generator provided in the R&S UPL-B10, it
is no longer necessary to look up IEC/
IEEE bus commands.
Universal Sequence Controller R&S
UPL-B10
The R&S UPL-B10 is used to generate and
execute measurement sequences, thus
turning the R&S UPL into an automatic
test system.
Measurement sequence programming is
greatly facilitated by the built-in program
generator: Each manual control step is
recorded in the logging mode and translated into a complete line of the sequence
program with correct syntax, i.e. test
sequences can be programmed without
the user typing a single line. The generated program does not just specify the
sequence of keys to be pressed but contains the instructions in easy-to-read IEC/
IEEE bus syntax according to SCPI.
BASIC commands can then be used to
modify the program, e.g. for branching or
graphic outputs.
Complete application programs based on
the universal sequence controller are
available for measurements on CD players, tuners, etc.
The universal sequence controller can also
be used for remote control of external
equipment via the IEC/IEEE bus or the RS232-C interface. Moreover, programs generated on the R&S UPL can be transferred
to an external controller after slight modifications for the remote control of the R&S
UPL. This greatly facilitates the generation
of remote-control programs.
Test assemblies for electroacoustic converters frequently consist of
microphones and loudspeakers, whose frequency response must be
compensated. The equalizer function of the R&S UPL furnishes tailormade solutions for such tests. Comprehensive test routines can be
implemented with the aid of the universal sequence controller.

Options and further applications
Fig. 13: Transfer and coherence function for determining the
transfer characteristic with the aid of complex test signals
(e.g. music or voice).
Low Distortion Generator R&S UPL-B1
This option is essential for all applications
requiring extremely pure analog signals
or an extended frequency range up to
110 kHz.
When digital audio data is produced by
the universal generator, the low distortion
generator may generate an analog signal
or be used for superimposing jitter or
common-mode interference.

Fig. 15: Third-octave analysis used mainly in acoustics.
Digital Interfaces R&S UPL-B2/-B29
These options contain the digital audio
interfaces (balanced, unbalanced and
optical) for the standard sampling rates
44.1 kHz and 48 kHz, and the R&S
UPL-B29 also covers the extended rates
up to 96 kHz. Either the R&S UPL-B2 or the
R&S UPL-B29 can be installed. A detailed
description of these options and their
software extensions (Digital Audio Protocol R&S UPL-B21, Jitter and Interface
Tester R&S UPL-B22 as well as the Coded
Audio Signal Generation R&S UPL-B23)
can be found on pages 8 and 9.
Audio Monitor R&S UPL-B5
This option adds a headphone output and
a built-in loudspeaker to the R&S UPL. The
input signal and – in the case of level,
THD+N and rub & buzz measurements –
the filtered or weighted signal can be monitored.
Extended Analysis Functions R&S UPL-B6
In modern audio systems, the transfer
characteristics are dynamically adapted to
the input signals. When conventional,
static test signals are used as input signals, the dynamic processes are not activated and thus the signals cannot be analyzed. The coherence and transfer functions are the solution to this problem:
Fig. 16: Different signals for both channels may be generated
at the digital audio outputs.
14
Audio Analyzer R&S UPL
speech, music, noise, etc, are used as test
signals, and the transfer characteristic is
represented by analyzing the output spectrum referenced to the input spectrum
(Fig. 13). The required complex test signals stored in various formats can be
directly called from the R&S UPL hard
disk.
With the rub & buzz measurement, manufacturing defects of loudspeakers can be
found in no time by measuring the
unwanted signals in the frequency range
above that of typical distortion products
(Fig. 14).
The third-octave analysis is an important
measurement in acoustics. The levels of
up to 32 third-octave bands are simultaneously measured in compliance with
class 0 of IEC1260 (Fig. 15).
In multitone signal generation, the R&S
UPL-B6 also allows the phase and crest
factor to be set. The R&S UPL-B6 is also
required for generating two-channel sinewave signals at the digital outputs
(Fig. 16).
Further functional extensions of the R&S
UPL-B6 are currently being developed.
Hearing Aids Test Accessories
R&S UPL-B7
The Audio Analyzer R&S UPL with the
option R&S UPL-B7 forms a complete test
system for all standard measurements on
hearing aids. The R&S UPL merely needs
to be equipped with options R&S UPL-B5
and R&S UPL-B10. The R&S UPL-B7
includes an acoustic test chamber as well
as all accessories required for measurements on hearing aids such as battery
adapters, connecting cables and acoustic

couplers. The associated software
enables complete measurements in
accordance with IEC60118 or ANSI
S3.22. *)
Acoustic measurements on GSM
mobile phones with the R&S UPL16 or
option R&S UPL-B8/-B9
The acoustic transmission and reproduction quality of a mobile phone is the most
important characteristic in everyday use.
The Audio Analyzer R&S UPL16 was
developed for conformance tests on GSM
mobiles. It performs all audio measurements in line with chapter 30 of GSM
11.10 and 3GPP TS 51.010 Release 99,
phase 2. Access to the internal digital signals of special test mobile phones is via
the standard digital audio interface (DAI).
Network operators, consumer test institutes, etc, are particularly interested in
measuring and comparing acoustic char-
acteristics of commercial mobiles.
A highly accurate test method is also
required for quality assurance and sampling inspection in the production of
mobile phones.
The Remote Control R&S UPL-B4
enables remote control of R&S UPL via
the RS-232-C interface or IEC625/
IEEE488 interface. The commands largely
meet SCPI standards.
The Mobile Phone Test Set R&S UPL-B8 is
available for these applications. With the aid
of this option all necessary audio measurements can be performed on GSM mobile
phones without the DAI interface. The
3G Mobile Phone Tests R&S UPL-B9 provide the same functionality, but expanded to
3G mobile phones and to the latest 3GPP
specifications TS26.131 and 132. These tests
are validated and can therefore be used for
type approvals. R&S UPL-B8 and -B9 require
options R&S UPL-B6 and -B10. For further
information refer to data sheet
PD 0757.5889, Acoustic Test of GSM
Mobiles.
The Universal Sequence Controller
R&S UPL-B10 allows measurement
sequences to be generated and executed.
For detailed information see page 13.
The Automatic Audio Line Measurement to ITU-T O.33, R&S UPL-B33
performs automatic measurements of all
relevant parameters of broadcast links
according to ITU-T O.33. The generator
and analyzer are normally located at different sites. Operators may utilize the
standard sequences defined by ITU-T
O.33 or prepare their own. Option R&S
UPL-B10 is needed for the use of the R&S
UPL-B33.
With option LAN Interface R&S UPLB11, the Audio Analyzer R&S UPL can be
connected to Novell networks in line with
10/100 BASE-T standard in order, for
example, to exchange data or access the
network printer (not for R&S UPL16).
The 150 Ω Modification R&S UPL-U3
changes the source impedance of the
analog generator from 200 Ω to 150 Ω.
