r&s®upv-九游官网下载

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 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
