Measurements on CD Players using the Audio Analyzers UPL or UPD and the Audio Test Disc UPA-CD

To analyse the quality of CD players, lots of measurements have to be done. This application note presents a program, which combines these measurements to an automatically running sequence and gives a printout of the results. A test CD is used for generating the test signals. Here the Audio Test Disc UPA-CD from Rohde & Schwarz is used, which holds all required signals in a sequence permitting automatic measurements to be carried out, without the need of controlling the CD player. In addition, this application note explains the measurements and informs about the different standards.
