29 September 2014 - The R&S RTO-K40 MIPI RFFE serial triggering and decoding option from Rohde & Schwarz is a powerful solution that enables developers of RF frontends and modules with RF frontend (RFFE) control interface to verify and debug designs and put these components into operation. The R&S RTO oscilloscope with its high acquisition rates and minimal blind times is able to trigger on MIPI RFFE-specific protocol data. The decoded protocol content is displayed in an easy-to-read format.
The R&S RTO-K40 option allows users to directly trigger on content such as "extended register write" or error states such as "bus park error" of the MIPI RFFE protocol. This option is the only tool on the market that supports automatic rejection of glitches during decoding as specified in the standard. The decoded protocol content is displayed in an easy-to-read, color-coded overview as well as in tabular format.
The powerful search and navigation function helps users to keep track of even long records and to directly jump to positions of interest in the protocol. As a result, users can easily isolate states, quickly identify design bugs and time-correlate decoded RFFE commands with other signals in the circuit under test. The R&S RTO oscilloscope allows parallel decoding of up to four different serial protocols so that any interactions between modules can be immediately detected. The MIPI RFFE interface can be connected to both the analog and digital channels of the oscilloscope.
The MIPI RFFE interface has been specified by the Mobile Industry Processor Interface (MIPI) Alliance for controlling components of the RF frontend such as output amplifiers, filters, power regulation modules and sensors.
The R&S RTO-K40 serial triggering and decoding option is now available from Rohde & Schwarz.
