Test & Measurement R&S®UPV Audio Analyzer Compact instrument for all audio measurements

R&S®UPV Audio Analyzer At a glance Although audio signals are mainly processed digitally nowadays, analog technology will remain a viable alternative that is continuously being enhanced. Therefore, both analog and digital measurements must be performed. The R&S®UPV audio analyzer is designed precisely for this purpose. The R&S®UPV enables users to perform virtually all measurements that are necessary in the audio world: frequency response measurement, total harmonic distortion (THD) displays, spectral displays, analysis of digital interfaces, and much more. The generator is just as versatile....

The generator of the R&S*UPV audio analyzer generates a variety of signals, here a 32-tone signal: Frequency, amplitude and phase can be The generators of the R&S®UPV can generate a wide variety of analog and digital test signals Sinewave signal... Dual-channel sinewave signals Different signals are always possible on both digital output channels; for the analog interfaces, the R&S®UPV-B3 op- Two-tone signal... ...for modulation distortion analysis; various amplitude ra- tios can be selected; continuous frequency adjustment is Difference-frequency distortion... ...for intermodulation measurements...

The R&S®UPV can perform a broad scope of measurements on both analog and – optionally – digital interfaces During the THD measurement, all, individual or any combination of harmonics can be measured. Even less common measurement functions such as the measurement of the dynamic intermodulation (as seen here) can be performed using the R&S®UPV audio analyzer. Level or S/N measurement... ...with RMS, peak or quasi-peak weighting; integration times that are automatically adapted to the input signal produce high measurement speeds Selective level measurement The center frequency of the bandpass can...

Efficient as well as multichannel FFT analysis with a resolution down to the mHz range The R&S®UPV offers several FFT capabilities; each of them is designed for two- or multichannel applications and can be applied to the filtered input signal. The FFT measurement function is used when high require- ments are placed on the dynamic range. Up to 256k points can be selected in binary steps, where the points are eval- uated in double precision mode. The post FFT can be used, for example, in THD and intermodulation measurements to analyze the distortion products in greater detail. Up to 256k points...

Everything included: no peripherals required The R&S®UPV audio analyzer is a compact instrument that already contains an integrated PC. The disadvantages of audio analyzers that are controlled from an external PC can therefore be avoided. The instrument is easy to transport, and no additional keyboard, monitor or other PC peripherals are needed. The R&S®UPV comes ready to use right out of the box. Users only need to unpack it, switch it on and start measuring. When an audio analyzer is operated using an external PC, the computer itself, the monitor or the interface connections can emit a level...

Largest variety of interfaces offered in a single instrument Analog generator outputs as standard ❙❙ Balanced outputs, floating (e.g. for avoiding hum loops) ❙❙ The generator outputs can be connected internally to the analyzer inputs so that changes in measurement tasks can frequently be handled without any external recabling being necessary Dual-channel analyzer with analog inputs as standard ❙❙ Dual-channel, balanced inputs with high common-mode rejection and various impedances that are common in studio equipment; lines with phantom powering can be measured ❙❙ Due to the wide dynamic range...

Digital audio interfaces for professional studio operation and for the consumer electronics Digital audio equipment can be interconnected via stan- dardized interfaces. With professional equipment, the AES/EBU format has become standard; with consumer equipment, the S/P DIF interface is used. The R&S®UPV-B2 option supports both areas: i Balanced (XLR), unbalanced (BNC) and optical (TOSLINK) inputs and outputs for connecting consumer electronics equipment and professional studio equipment i The level of the balanced and of the unbalanced output can be adjusted so that the sensitivity of digital...

Jitter and interface test (R&S®UPV-K22 option) This option enables the user to analyze the physical parameters of the digital audio interface. The R&S®UPV-K22 option expands the functionality of the R&S®UPV-B2 option. Analysis ❙❙ Measurement of the jitter amplitude and display of the jitter signal in the frequency and time domains ❙❙ Measurement of the input pulse amplitude and of the sampling frequency ❙❙ Measurement of the phase between audio input and reference input ❙❙ Analysis of the common-mode signal of the balanced input (frequency, amplitude, spectrum, etc.) Generation ❙❙ The clock of...

Virtually any audio circuit adaptable using the universal serial interface (R&S®UPV-B42 option) Although numerous digital audio applications can use dual-channel data transmission, there is a strong trend toward formats that transmit more than two data channels. At the same time, numerous data formats are being developed. To accommodate all of these applications, the R&S®UPV-B42 universal serial interface option was developed. It can be inserted into one of the two slots on the rear of the R&S®UPV audio analyzer. The generator and analyzer can be configured independently of each other, and they...
