Universal Trigger and Decoder Option for R&S Digital Oscilloscopes

Rohde & Schwarz has expanded its range of trigger and decoder options for the R&S RTO and R&S RTE digital oscilloscopes. With the R&S RTx-K50, the oscilloscopes help you debug serial protocols that employ Manchester or NRZ coding. The option can be used with a variety of standardized buses (e.g., PROFIBUS, DALI, or MVB) as well as with proprietary serial protocols. Developers of products that use these types of interfaces can easily find implementation errors and so test and release their designs more quickly.RTO-Rohde

The option, which covers data rates of up to 5 Gbps, supports up to 50 different telegram formats, while the format of the serial bus can be configured flexibly. You can define your 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 oscilloscopes. You 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.
