Audio analysers

9 June 2010 Test & Measurement

Rohde & Schwarz has introduced a new family of audio analysers developed especially for use in production. The R&S UPP200/400/800 analysers are available in two-, four- or eight-channel versions and multiple analysers can be cascaded to test as many as 48 analog measurement channels. Due to the units’ capability to perform parallel measurements on all channels, manufacturers of audio equipment of any type can achieve high throughput in production.

Depending on the requirements, up to five slave instruments can be connected to a master via cascading. This system operates like a measuring instrument with a maximum of 48 channels. All the channels of a 16-channel sound system, for example, can be measured in a single step if two eight-channel analysers are connected. As an alternative, one R&S UPP800 can be used to simultaneously test up to eight single-channel DUTs.

Since the new analysers include a built-in computer, all operations run in the base unit and the controller of the test system does not need to be equipped with software to control the analyser. The compact audio analyser comes without a graphical user interface, however, users can connect a monitor, keyboard and mouse to create a standalone instrument.
