Form 080/01 Data Sheet | 03.00 Test & Measurement R&S®UPZ Audio Switcher Multichannel switcher for audio channel inputs and outputs R&S®UPZ Audio Switcher At a glance Multichannel switcher for audio channel inputs and outputs As an add-on unit to the R&S®UPV audio analyzer, the R&S®UPZ audio switcher can be used whenever input or output signals have to be switched over to multiple channels or DUTs. Users can directly operate the switcher from the graphical user interface of the audio analyzer. Control via any PC is also possible. Key facts JJ Available as input and output switcher of up to 128 channels JJ Operation directly from the R&S®UPV audio analyzer JJ Control via RS-232-C for handling universal applications JJ Cascading Rear view of the R&S®UPZ. Several R&S®UPZ switchers can be cascaded. 2 R&S®UPZ Audio Switcher Benefits and key features Wide variety of applicatons for all kinds of audio measurements Surround applications in homes, multichannel mixing consoles in sound studio environments, multichannel amplifiers as well as the adaptation of several DUTs in production are just some examples of the wide variety of applications that are possible using the R&S®UPZ audio switcher. As an add-on unit to the R&S®UPV audio analyzer, the R&S®UPZ is directly operated from the R&S®UPV graphical user interface. Remote control, e.g. in production environments, also runs via the R&S®UPV audio analyzer. Users can also control the R&S®UPZ audio switcher directly from a PC via its RS-232-C interface. Available as input and output switcher The R&S®UPZ audio switcher – like the R&S®UPV audio analyzer – is provided with XLR connectors. Since there is a difference between male and female connectors in the XLR system, the R&S®UPZ is available both as an input and as an output model. The R&S®UPZ together with the R&S®UPV. Both models feature two switching channels, enabling users to simultaneously operate the two generator or measurement channels of the R&S®UPV. Up to 16 input switchers plus 16 output switchers can be cascaded, allowing up to 128 input or output channels to be switched. Applications for testing multichannel amplifiers The standard application is a paired or individual switchover of the DUTs or measurement channels to be tested. In each case, one signal path is connected to an assigned channel. A special feature is measuring the crosstalk of the individual channels for multichannel amplifiers, which requires a particularly critical measurement. The signal coupled into a channel will then be measured while all other amplifier channels are driven at the same time. For this application, the output switcher enables users to switch signal path B through to all channels in parallel, while signal path A can be switched to any one selectable channel.
