01 September 2011 Audio analyser with new digital audio interface options Audio analyser with new digital audio interface options Agilent Technologies has introduced the enhanced Agilent U8903A audio analyser with new digital audio interface options. These options are designed to expand the U8903A's capabilities with AES3, SPDIF and digital serial interface (DSI) formats for analogue 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 range of digital audio applications. The upgraded U8903A audio analyser contains the full functions of analogue domain and digital domain audio measurement in a single unit. It offers a logic level input range of 1.2 to 3.3V and allows users to set the logic level to any value within that range. This allows the U8903A to support and test future designs with continuously smaller logic levels in addition to the majority of current digital audio ICs. It is equipped with a 5.7in colour screen - capable of displaying up to four channel results simultaneously - and one button access to four main operating modes through the front panel softkeys. Existing U8903A users can obtain the digital audio interfaces by opting for a hardware upgrade, which includes installation of selected digital audio interface options and calibration of the U8903A unit by Agilent's Service Solution Unit.
