Audio analysis today and tomorrow

Analog and digital

Audio signal processing is nowadays no longer conceivable without the use of digital techniques. Yet, analog technology continues to exist and undergoes constant improvement. State-ofthe-art measuring instruments must therefore be able to handle both analog and digital signal processing.

Audio Analyzer UPD performs practically all types of audio measurement, from frequency response measurements through to externally controlled sweeps with reference traces, determination of

3rd-order difference frequency distortion, spectral display of demodulated wow and flutter signals, etc. In contrast to many other audio analyzers, UPD is capable of performing real dual-channel measurements in the audio-frequency range, ie there is no need for switchover between two inputs and this type of measurement is not limited to a few special cases.

The generator is every bit as versatile: it supplies any conceivable signal from sinewave and noise signals through to multi-sinewave signals comprising up to

7400 frequencies.

In addition to all this, UPD 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, FFT with a maximum frequency resolution of

0.02 Hz, etc.

UPD 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 many more features.

Superior analysis concept

UPD 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 converter. This provides sufficient margin for measuring converters of the future, which will be technically more advanced than those of present-day technology (see graph on the right). This concept guarantees performance and flexibility by far superior to instruments providing purely analog or digital measurements.

The above measurement concept offers many other advantages over merely analog concepts:

• The test routines for analog and digital interfaces are identical. This allows, for instance, the direct comparison of IMD measurements made ahead of and after a converter

• In intermodulation measurements, spurious components are measured selectively for all frequencies in accordance with the mathematical formula of the relevant test standards. This procedure avoids the measurement of adjacent components along with the spuria, which is usually inevitable with analog test methods

Digital analysis and analog preprocessing

A future-proof investment

Nobody can accurately predict today what effects future developments in digital technology will have on the audio world and what will be the resulting test requirements. This is however no problem for Audio Analyzer UPD. Since all test functions are implemented digitally,

UPD can be adapted to changing requirements by simply loading the necessary software – and this also for the analog interfaces.

And one more thing: Rohde & Schwarz is the only manufacturer to equip its audio analyzers with 32-bit floatingpoint signal processors throughout, thus offering plenty of reserves beyond the limits of today’s common 24-bit technology.

The intelligent combination of analog and digital measurement techniques paves the way for future applications

• All test functions are available both on the analog and the digital interfaces. This makes it possible to measure at any point of a common analog and digital transmission path. Only this ensures efficient and complete testing

• The filters, too, are implemented digitally, resulting in an infinite number of filters as it were, and this also for measurements on analog interfaces. Simply choose the type of filter (eg highpass), cutoff frequency and attenuation: that’s all you have to do to loop a new filter into the test path

• Measurement speed is as a rule 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

Test signals – as you like it

The generators of UPD supply an extremely wide variety of analog and digital test signals:

Sinewaves

for level and harmonic distortion measurements. The signal can be applied to an equalizer with userselectable nominal frequency response, eg 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

comprising up to 17 sinewaves of any frequency and with the same or different amplitude; setting the phase is also possible

Sine burst signal

with adjustable interval and ontime as well as programmable low level, eg for testing AGCs

Sine

2

burst

also with adjustable interval and on-time, eg for testing rms rectifier circuits

Special multitone signal

comprising 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 singleshot measurements of the frequency response of a DUT

Squarewave

as an ideal signal for measuring the transient response of a DUT

Signal for dynamic intermodulation measurement (DIM)

consisting of a squarewave and a sinewave signal with a level ratio of 4:1

Noise

with a variety of amplitude probability distributions, eg for acoustic measurements; crest factor can be set

Arbitrary waveforms

for generating any voltage curve of up to 16k points

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 measurement functions

UPD offers a wealth of measurement functions both for analog and digital interfaces.

Level or S/N

with rms, peak or quasi-peak weighting; high measurement speeds due to automatic adaptation of integration times to 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

(eg for fast frequency response measurements) or to the input signal

Coherence and transfer functions

for determining the transfer characteristics of complex test signals

Tests on hi-fi components call for increasingly complex measurement techniques. Results obtained in the test lab must be verified in production, where as a rule not the whole range of test functions is needed. Audio Analyzer UPD and its „little brother“ UPL complement each other. The operating concept of the two units based on the same

IEC/IEEE-bus commands is identical, so there is no problem using them jointly

Fig. 5: FFT spectrum of two-tone signal shown on full screen

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

Spectrum analysis

With its FFT analyzer, UPD 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 256 over a selectable range. In this way, a maximum resolution of 0.02 Hz is attained.

It should be emphasized that this is not just a scale expansion but the measurement is really made at a higher resolution (Fig. 6).

In measurements of external signals, these 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. Results will be stable even for

DUTs with unknown or unstable transient response thanks to the settling function.

Programmable filters

The filters of UPD are software-implemented so that the user can define any number of filters. The most common weighting filters are provided as standard. Further 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 shows its strength in particular where special requirements have to be met: special filters can be implemented using commercial filter design programs. The data are transferred to

UPD and the created filter is looped into the signal path.

A variety of sweep functions

For continuous variation of the test signals, UPD offers amplitude and frequency sweeps and for bursts additionally sweeps of interval 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.

Audio Analyzer UPD

All-in package

Audio Analyzer UPD is a compact unit with an integrated controller. It avoids the disadvantages of external PC control, which is 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.

UPD is supplied ready for use. Installation is nothing more than unpacking the unit and switching it on for starting the measurement. The user is not burdened with problems that cropped up in the past with the installation of interface cards or PC software.

With audio analyzers controlled from an external PC, interference may be radiated from the PC, monitor or interface connections, which distorts measurement results. Not so with UPD: the instrument has specified EMC characteristics which also include the internal

PC. In contrast to conventional PCs,

UPD features elaborate screening such as magnetically shielded power transformers and coated filter pane in front of the display.

And a real boon: the price of UPD includes the internal PC.

• 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 are supplied as standard

• Remote control via IEC/IEEE bus

• Postprocessing of results directly in

UPD 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. Easy generation of programs with built-in program generator

Fig. 12: UPD generates and analyzes additional data in digital data streams in line with all common standards. The data are represented in binary form, as hexadecimal numbers, as ASCII characters or evaluated in consumer or professional format

Analog interfaces

• Balanced inputs and outputs with high common-mode rejection and various impedances commonly used in the studio. Measurements can be made on lines with phantom feed

• Unbalanced inputs and outputs, floating (eg to prevent hum loops)

• The generator outputs can be internally connected to the analyzer inputs so that different types of measurement can be made without the need for changing the cabling

• The format of the generated channel status data may be professional or consumer irrespective of the selected interface

• 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 between 8 and 24 bits independently for generator and analyzer

Programmable digital audio interfaces

• Parallel inputs and outputs for connecting modules or converters with parallel interface

• Serial inputs and outputs for adapting modules with a non-standard serial interface or audio chips. This interface is user-programmable, ie by selecting the word length, clock polarity, position of sync pulse, etc, it can be matched to almost any serial format, eg also to I

2

S bus

• Word lengths up to 32 bits with max. 28 audio bits open up a wide application range. Clock rates up to 1 MHz (word clock) can be processed

Standardized digital audio interfaces

(option UPD-B2)

• Balanced (XLR), unbalanced (BNC) and optical (TOSLINK) inputs and outputs for connecting consumer electronics and professional studio equipment

• The levels of the balanced and unbalanced outputs are adjustable so that the sensitivity of digital audio inputs can be determined

• Analysis of channel status and user data. The data are output in binary form, as hexadecimal numbers, as

ASCII characters or, in the case of channel status data, evaluated in the professional or consumer format to AES 3 or IEC 958 (Fig. 12)

8

Audio Analyzer UPD

• Generation of channel status data, user data and validity bits.

Channel status data can be entered in binary form or via panel to

AES 3 or IEC 958 in 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)

• Generation of parity and CRC errors, etc, for testing input circuits

• An additional high-impedance input permits measurements to be performed without opening the signal path

Jitter and interface tests

(option UPD-B22)

With this option, the physical parameters of digital audio interfaces can be examined. UPD-B22 extends the functions of option UPD-B2

Digital components of various data formats and clock rates are the stock-in-trade of professional users. They call for a measuring instrument offering top performance at all interfaces at 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 analysis:

• Measurement of jitter amplitude and display of jitter signal in the frequency and time domain

(Figs 9 and 10)

• UPD generates bit- or word-synchronous 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

• Analysis of common-mode signal of balanced input (frequency, amplitude, spectrum, etc.)

Signal generation:

• The clock of the output signal can be “jittered“ by superimposing a sinewave or noise signal of variable amplitude

• 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

• A reference (XLR) input and a synchronization (BNC) input provided on the rear panel allow the generator to be synchronized to the digital audio reference signal to

AES 11, word clock, video sync signals (PAL, SECAM, NTSC) and to 1024 kHz reference clocks

• Generation of variable clock signals from 30 kHz to 52.5 kHz, also for operating UPD-B2

• Adjustable pulse amplitude

Designed for convenience

Efficient online help

UPD offers a variety of help functions to provide optimum support for the user:

HELP function

HELP information in German or English can be called for each input field.

SHOW I/O key

If no results can be displayed, eg because no input signal or an incorrect input signal is present, 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 inform the user of any incorrect settings.

Online help

The permissible range of values is indicated for each menu item requiring the entry of a numerical value. This range takes into account any limitations resulting from related parameters, eg the sample rate in the case of measurements on digital interfaces.

Protection against illegal entries

UPD 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.

A wealth of functions – yet easy to operate

• Related functions and settings are combined in panels that can be called 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 given 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 simplify familiarization with the instrument

• Uncomplicated entries: the user simply needs to open a menu and make an entry or selection

• Continuous status information on generator, analyzer and sweep

• Rapid operating sequences through the use of softkeys, eg for graphical representations

• The user can choose between operation via mouse, external keyboard or front panel. This choice makes sense since the working space required by a mouse is not always available

• Short learning time thanks to an easy-to-understand operating concept treating analog and digital measurements in the same way

10

Audio Analyzer UPD

Results at a glance

• Real-time 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 modes range from traces and bargraphs through spectrum display to three-dimensional waterfalls

It is often the case that 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 marking them with a tick. 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

UPD can also be operated from the status panel

Fast and efficient

High measurement speed

In designing Audio Analyzer UPD, particular emphasis was placed on optimizing the measurement speed of the test system as a whole:

• All operations involving elaborate computing are carried out by digital signal processors. The PC is merely used for control of the unit and display of results

• UPD can perform even complex test functions simultaneously on both channels with the built-in highspeed option UPD-B3. This feature alone reduces the time for stereo measurements by 50% compared with most analyzers available on the market

• The digital test routine adapts its speed optimally to the input frequency. This enhances measurement speed especially in the case of frequency sweeps

• UPD 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)

• User interface tailored to the requirements of a test, not of an office environment

• Display windows not needed can be switched off, which also cuts down the processing time

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/nogo decisions can be made already in the audio analyzer, thus reducing the run time of a DUT

(Fig. 8)

• Two-channel measurements allow the simultaneous and thus timesaving 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 time-critical

• Long calibration intervals, resulting from the extensive use of digital circuits, make for high availability of the instrument

• Remote-control capability via the

IEC/IEEE bus is a must in large-scale production systems. In the design of

Audio Analyzer UPD, 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 UPD-K1, it is no longer necessary to look up IEC/

IEEE-bus commands

12

Audio Analyzer UPD

Options for further applications

Low distortion generator

The low distortion generator is essential for all applications requiring extremely pure analog signals or generation of an analog DIM signal.

Its inherent distortion is well below that of the built-in universal generator which already has excellent specifications.

Audio monitor

The optional Audio Monitor UPD-B5 adds a headphones output and a builtin loudspeaker to UPD. During rms measurements in the frequency range up to 20 kHz, the input signal and the filtered signal can be monitored at the interfaces of the analog analyzer and the AES/EBU option.

UPD-B5 is also provided with four TTL inputs and eight TTL outputs which can be used for instance for switching checkpoint selectors.

AES/EBU interface

This interface option (UPD-B2) contains the AES/EBU, the S/P DIF and the optical interfaces. An additional signal processor on the PCB permits also user bits, status bits, parity and

CRC errors, etc, to be generated and analyzed in addition to audio data.

Input and display masks can be userdefined with the aid of configuration files for adapting the interface to any protocol. Ready-made masks are available for protocols to AES3 or consumer format. The output level of the interface can be programmed. An additional high-impedance input enables measurements without opening the signal path.

IEC/IEEE-bus option

IEC-625/IEEE-488 bus Interface

UPD-B4 enables remote control of UPD to IEC 625/IEEE 488. The employed commands largely meet SCPI standards.

Option UPD-B22 permits also the physical parameters of the serial bit stream of the digital audio interface to be investigated (for details refer to page 9).

High-speed option

UPD was designed for high measurement speed. For this reason all analog switching circuits are provided with two channels. Operations for the two measurement channels are calculated in time multiplex. If higher measurement speed is needed – eg in production – the optional High speed Extension UPD-B3 can be used. With the aid of this option digital processing too is performed in parallel for the two channels.

Universal sequence controller

This option (UPD-K1) allows measurement sequences to be generated and executed, thus turning UPD into an automatic test system. Programming of measurement sequences 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, ie test sequences can be programmed without a single line to be typed by the user. The program thus generated does not just give 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, eg for branching or graphic outputs.

Complete application programs based on the universal sequence controller are available to the user for measurements on CD players, tuners, etc.

With the IEC/IEEE-bus option

(UPD-B4) fitted, the universal sequence controller can also be used for remote control of external IEC/IEEE-bus equipment. Moreover, programs generated on UPD can be transferred after slight modifications to an external controller for the remote control of UPD. This greatly facilitates the generation of remote-control programs.

Automatic line measurement

Option UPD-K33 serves for automatic measurements of all relevant parameters of broadcast links according to

ITU-T O.33. Generator and analyzer are normally located at different sites.

They are synchronized with the aid of

FSK signals. The operator may utilize the standard sequences defined by

ITU-T O.33 or prepare his own.

Option UPD-K1is needed for the use of

UPD-K33.

Averaging

Filter

For all analog and digital analyzers. Up to 4 filters can be combined as required. All filters are digital filters with a coefficient accuracy of 32 bit floating point (exception: analog notch filter).

Weighting filter

– A weighting

– C message

– CCITT

– CCIR weighted, unweighted

– CCIR ARM

– deemphasis 50/15, 50, 75, J.17

– rumble weighted, unweighted

– DC noise highpass

– IEC tuner

– jitter weighted

User-definable filters

Design parameters:

8th order elliptical, type C (for highpass and lowpass filters also 4th order selectable), passband ripple +0/–0.1 dB, stopband attenuation approx.

20 dB to 120 dB selectable in steps of approx. 10 dB (highpass and lowpass filters: stopband attenuation 40 dB to 120 dB).

Highpass, lowpass filters

Bandpass, bandstop filters limit frequencies (–0.1 dB) selectable, stopband indicated passband (–0.1 dB) selectable, stopband indicated

Notch filter

Third octave and octave filters center frequency and width (–0.1 dB) selectable, stopband indicated center frequency selectable, bandwidth (–0.1 dB) indicated

File-defined filters any 8th order filter cascaded from

4 biquads, defined in the z plane by poles/zeroes or coefficients

Analog notch filter

For measurements on signals with high S/N ratio, this filter improves the dynamic range of the analyzer by up to 30 dB to 140 dB for analyzer 22 kHz, or 120 dB for analyzer 110 kHz/300 kHz (typical noise floor for FFT). The filter is also used for measuring THD, THD+N and MOD DIST with dynamic mode precision.
