R&S RTO and R&S RTE now with universal trigger and decoder option for Manchester- and NRZ-coded buses

08/18/2015

Rohde & Schwarz has again expanded its range of trigger and decoder options for the R&S RTO and R&S RTE. With the R&S RTx-K50, the oscilloscopes help users debug serial protocols that employ Manchester or NRZ coding. The option can be used with a variety of standardized buses such as PROFIBUS, DALI or MVB as well as with proprietary serial protocols such as are typically found in industrial environments and in the aerospace & defense sector. Developers of products that use these types of interfaces can easily find implementation errors and so test and release their designs more quickly.

The option, which covers data rates of up to 5 Gbit/s, supports up to 50 different telegram formats, while the format of the serial bus can be configured flexibly. Users can define their own preamble, frame ID, data, CRC and other telegram fields. Protocol decoding also takes Manchester code violations into account.

High acquisition rates and minimal blind times are provided by the hardware-based trigger implementation on the R&S RTO and R&S RTE oscilloscopes. Users can trigger on telegram and data content with the R&S RTx-K50 option. The decoded protocol content is displayed in an easy-to-read, color-coded format. Time correlation with the analog signal makes it easy to identify faults caused by signal integrity problems. A tabular list of the protocol contents is also provided. The standard mask test with up to 600 000 tests per second makes it possible to check the signal quality faster with an eye diagram than with any other solution. In addition, both oscilloscope series from Rohde & Schwarz support the option of decoding up to four different serial protocols in parallel.

The R&S RTO-K50 and R&S RTE-K50 serial triggering and decoding options for protocols using Manchester or NRZ coding are now available from Rohde & Schwarz.
