Agilent Technologies has endowed its U8903A audio analyser with new digital audio interface options.
These options expand the instrument’s capabilities with AES3, SPDIF and DSI (digital serial interface) formats for versatile, high-performance analog and digital audio testing.
The DSI format offers four sub formats – I²S, left justified, right justified and DSP – for R&D engineers to analyse and verify a wide range of digital audio applications. The upgraded audio analyser contains the full functions of analog domain and digital domain audio measurement in a single unit, allowing engineers and technicians to perform complex cross-domain measurements in industries such as IC component and module design, wireless communications and consumer audio.
The U8903A offers a wide logic level input range of 1,2 V to 3,3 V and allows users to set the logic level to any value within that range. This allows it to support and test future designs with continuously smaller logic levels in addition to the majority of current digital audio ICs. Built for ease of use, the unit is equipped with a 5,7-inch colour screen (capable of displaying up to four channel results simultaneously) and one-button access to four main operating modes through the front panel soft keys.
