The Rohde & Schwarz UPD is a versatile instrument for measuring the full range of audio parameters at analog and digital interfaces. Audio Analyzer UPD is largely identical with UPL. UPD has a wider frequency and level range and more interfaces. Moreover, free slots are available in the processor section for commercial plug-in boards.
Additional measurements
User-programmable digital interfaces enable measurements on modules and audio chips that have no standardized audio interfaces. In the development of A/D and D/A converters, Audio Analyzer UPD can thus be adapted to virtually any data format via its serial or parallel lines. Clock rates are selectable between 100 Hz and 1 MHz, which covers both slow rates for telephone applications and fast rates for oversampling modules.
UPD can generate squarewave and FM-modulated signals
UPD generates protocol errors (eg CRC, parity, sequence errors) at digital interfaces for testing input circuits.
