4.2 Functional Division of the Audio Analyzer
4.2.1 Instrument Concept
The audio analyzer combines the following components in a single housing:
●
Generators with analog and – with the R&S UPP-B2 (digital audio interfaces)
option – also digital audio interfaces for generating the multiple test signals,
●
Analyzers with analog and – with the R&S UPP-B2 – also digital audio interfaces
for extensive measurement options and
●
a computer (PC) with the Windows operating system for controlling and operating
the entire instrument and with connections for peripherals and LAN.
4.2.2 Generators
4.2.2.1 Universal Generator
The universal generator consists of an FPGA and generates various test signals, from
sine-wave tones to intermodulation test signals (two-tone signals) to noise signals and
multi-tones. Following appropriate conversion, these signal are made available at the
analog outputs.
With the R&S UPP-B2 (digital audio interfaces) option, they can also be output as digi-
tal data streams in various formats at AES/EBU and SPDIF interfaces and at optical
interfaces.
The R&S UPP-B4 option (HDMI and digital audio interfaces) allows channel status
data to be generated in the data stream of the digital audio interface of the generator
instruments "Digital Audio" and "HDMI".
All test signals can be output on both channels. However, different signals are also
available at the digital outputs.
