R&S®UPV-B2 Digital Audio Interfaces AES/EBU, S/P DIF
Key Facts
This option contains the digital audio interfaces according to AES3 / IEC 60958 (XLR, BNC and TOSLINK) for the standard sampling rates of 32 kHz to 192 kHz.
It can be complemented by the following options:
- R&S® UPV-K21 digital audio protocol for analyzing and generating digital auxiliary data (channel status, validity, parity)
- R&S® UPV-K22 jitter and interface test for analyzing the physical parameters of the digital audio interface
Digital audio interfaces for professional studio operation and for the consumer electronics market
Digital audio equipment can be interconnected via standardized interfaces. With professional equipment, the AES/ EBU format has become standard; with consumer equipment, the S/P DIF interface is used. The
- Balanced (XLR), unbalanced (BNC) and optical (TOSLINK) inputs and outputs for connecting consumer electronics equipment and professional studio equipment
- The level of the balanced and of the unbalanced output can be adjusted so that the sensitivity of digital audio inputs can be determined
- Simulation of long cable lengths by using an integrated cable simulator
- Adjustable phase shifting between digital audio and reference output
- The format of the generated channel status data can be selected independently of the selected interface, where the choices are "professional" and "consumer"
- Reference (XLR) and synchronization input (BNC) at the rear of the instrument; therefore, the generator can be synchronized with the digital audio reference signal (DARS) in line with AES11, or with a word clock
- Bit- or word-synchronous sync signals are generated that permit an accurate representation of the digital audio signal on an oscilloscope (preamble, eye pattern, signal symmetry, superimposed noise, etc.)
- Generator and analyzer can be operated with clock rates of 32 kHz to 192 kHz; the generator can also generate these clocks internally
- The clock rates of the analyzer and the generator are independent of each other, which allows clock rate converters to be analyzed
- Audio words of 8 bit to 24 bit can be selected independently for the generator and the analyzer
