Brief Description
The R&S®UPZ
audio switcher is a multichannel switcher for audio channel inputs and outputs.
Used with Rohde & Schwarz audio analyzers, it opens up further application
fields.
Key Facts
-
Available
as input and output switcher
-
Cascading
of up to 128 channels
-
Operation
directly from the R&S®UPV
or R&S®UPP audio analyzers
-
Control
via RS-232-C or USB 2.0 for handling universal applications
-
Features
& Benefits
-
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 and R&S®UPP audio
analyzers, the R&S®UPZ is directly
operated from the graphical user interface. Remote control, e.g. in production
environments, also runs via the audio analyzer.
-
Users can also control the
R&S®UPZ audio switcher directly from a PC via its RS-232-C or USB 2.0
interfaces.
-
Available as input and output switcher
-
The R&S®UPZ audio
switcher – like the R&S®UPV and R&S®UPP audio
analyzers – comes 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.
-
Both models feature two switching
channels, enabling users to simultaneously operate the two generator or measurement
channels of the audio analyzer.
-
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
paired or individual switching 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 of multichannel amplifiers, which
requires a particularly critical measurement.
-
For this application, the signal
coupled into a channel will be measured while all other amplifier channels are
driven at the same time. 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 selectable channel.
