Cost-efficient R&S UPP audio analyzer family reduces measurement times in production environments

Audio analyzers enable manufacturers to carry out the tests required to measure the quality of the audio equipment they produce, including CD players, car radios, mobile phones and hearing aids. The R&S UPP200/400/800 (two/four/eight channels) from Rohde & Schwarz is an analyzer family in the medium price range that helps ensure extremely short measurement times in production where costs are a major concern. 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 analyzers are connected. As an alternative, one R&S UPP800 can be used to simultaneously test up to eight single-channel DUTs, which is highly efficient and speeds up production.

Manufacturers who already use the R&S UPV high-end audio analyzer developed by Rohde & Schwarz for R&D applications can run the measurement programs from their R&D work on the new R&S UPP200/400/800. Both instrument types have nearly identical operation and remote control concepts. In addition, test cases from production can be checked by the R&D department, which means optimal collaboration between production and R&D.

Since the R&S UPP200/400/800 analyzers 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 analyzer. The compact audio analyzer comes without a graphical user interface. However, users can connect a monitor, keyboard and mouse to create a standalone instrument with an excellent price/performance ratio. As a result, the audio analyzer is also ideal for users with small budgets who wish to perform R&D tasks.

The R&S UPP200/400/800 audio analyzers with two, four or eight channels are now available from Rohde & Schwarz.
