the r&s®upv-b42 option expands the r&s®upv audio analyzer by adding universal, digital audio interfaces with which the parameters of the digital formats can be set with great flexibility. virtually all common audio chips can then be connected.
the generator and analyzer can be configured independently of each other, and they can be synchronized both internally and externally (master or slave mode). up to four data lines can be handled, where they can contain up to 256 audio data packets (slots) per frame in time multiplex.
one or two test signals can be output simultaneously in any number of user-selectable slots, and up to eight audio signals from any number of user-selectable slots can be analyzed simultaneously.
data formats up to 32 bit can be processed with sampling rates of 1 khz to 400 khz. the bit sequence, slopes and offset can be flexibly adjusted. a detachable probe permits short, low-reflection connections directly to the chips to be tested; all common logic levels are supported. in summation, the user enjoys flexible digital audio interfaces that can be connected to practically all audio chips currently in use.
