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 R&S®UPV-B2 option supports both areas:

    • 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
