I2S,
LJ, RJ and TDM are serial buses that implement unidirectional point-to-point
connections. They carry digital audio data between ICs and are often used to
connect analog-to-digital converters and digital-to-analog converters to
digital signal processors (DSP) for audio processing. The new option for the
R&S®RTO high-performance oscilloscope from Rohde & Schwarz addresses
the complex requirements in the development of electrical components equipped
with audio interfaces.
An
extensive selection of protocol-specific trigger conditions provides the user
with a high degree of flexibility when trying to detect specific data contents.
The R&S®RTO oscilloscope’s hardware-implemented triggers ensure high
acquisition rates for fast measurements. Explanatory graphics and links to
related settings significantly simplify configuration. Evaluating the test data
is also easy. Protocol details in the decoded bus signals are color-coded, and
protocol data is summarized. A track function displays the decoded audio signal
as an analog waveform. These features allow users to quickly and easily find
design problems that cause clipping, glitches and other anomalies.
