Audio Analyzer 110kHz, Opt.: B1 = Low Distortion Generator; B4= Remote Control; B5= Audio Monitor; B6= Extended Analysis Functions; and B10 = Universal Sequence Controller

Audio analyzer for GSM mobiles, DC to 110 KHz, 2 channels, analog and digital input, colour TFT display, GPIB.

Compact instrument for audio measurements at analog and digital interfaces.

Audio Analyzer UPL performs practically all types of analog 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, UPL is capable of performing real dual-channel measurements in the audio-frequency range, i.e. there is no need for switchover between two inputs and this facility 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, UPL features excellent technical data:

Analog sine-wave 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 0.05 Hz, etc.

UPL provides signal monitoring via loudspeaker during the test, jitter measurements on digital audio signals, resynchronization of jittered digital audio signals by means of a jitter-free clock signal, and many more features.

Audio Analyzer R&S UPL16 has the same superior analysis concept as all members of the R&S UPL family. The instrument is able to handle both analog and digital processing. It carries out practically all types of measurement in the audio range from frequency response measurements to distortion measurements, FFT analysis, etc.

The R&S UPL16 is especially designed for acoustical tests on GSM mobiles.

It is equipped with the digital audio interface (DAI) as defined in GSM phase 2 recommendation 11.10, section 36.4.

Thanks to this interface the R&S UPL16 can act as a system simulator or simulate a mobile.

UPL16:

Built-in Digital Audio Interface DAI

Test cases according to 3GPP TS 51.010-1

All kinds of analog and digital test signals including artificial voice

Measurements in analog and digital domain

UPL16 is part of Type Approval System TS8916

UPL16 + CRTx or CMU for type approval measurements

Validated measurements via Air Interface with option UPL-B9

Option B1:

Low distortion generator.

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

Two-channel analog generator, 2 Hz to 21.75 kHz, with low-distortion generator up to 110 kHz.

Single-channel digital generator, 2 Hz to 3.96 kHz

The standard analog generator can be supplemented by the low-disortion generator option B1 for sinewave generation in the analog range, thus allowing for generating a particular low-distortion sinewave with a frequency 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 simutaneously generated with option B1.

Option B4:

Remote Control :

Enables remote control via the RS-232-C interface or the IEC/IEEE-bus interface (IEC 625/IEEE 488)

Option B5:

Audio monitor:

Audio monitor (for analog input only)

The headphone/speaker output option B5 permits to monitor both analog and digital measuring and test signals during the measurement. For this purpose, the built-in loudspeaker or the externally connected headphones are used.

The impedance of the headphones should be 600 ohms so that a distortion-free operation is guaranteed even with full volume. When connecting headphones with lower impedance, distortions have to be taken into account depending on the power level.

The maximum peak voltage at the headphones is 8 volts.

The input signals of all analog analyzer (INPUT) ant the output signals of all analyzer level functions may serve as signal sources for the monitor output, in addition monitoring of THDN and Rub&Buzz residual signal can be switched on.

Option B6:

Extended Analysis Functions:

Coherence and transfer functions, rub & buzz measurement, third-octave analysis

Option B10:

Universal Sequence Controller:

Enables measurement sequences to be generated and executed with the aid of a built-in program generator
