Key facts

  • Display of all decoded telegrams as color-coded bus signals as well as in tabular format
  • Trigger on start of frame, frame ID, data and various error conditions (e.g. interbyte spacing, CRC, parity)
  • Powerful search and navigate capability on start of frame, frame type, data and error conditions
  • On-screen serial decoding is time-correlated with the serial data waveform
  • Fastest eye-diagram mask testing with standard mask test functionality
  • Multi-domain icon

Oscilloscope software

The R&S®RTO and R&S®RTE oscilloscopes support triggering and decoding of clock extension peripheral interface (CXPI) buses. You can set up decoding in seconds. For detailed analysis, results can be viewed as color-coded telegrams and/or in a table. Errors are identified efficently using the hardware-accelerated trigger. You can trigger on start of frame, frame ID, data and various error conditions.

Features & benefits

Fast bus setup

Bus setup in seconds with the app cockpit

Starting from the app cockpit, it only takes a few steps to configure any given protocol. Once the bus to decode has been chosen, the connected channels selected and the correct levels set, decoding begins automatically.

Color-coded telegram display

Telegram display as color-coded bus signals and in decode table

You can analyze the decoded bus frames by overlaying the signal with color-coded data. Address and data content can be displayed in hex, bin or ASCII format. You always have the best overview with the flexible screen setup. The protocol details can also be displayed in a concise table. Select the data format and decode layer that best fits your analysis needs.

Decoded frames are color-coded.

Strong trigger capability

Strong trigger capability on start of frame, frame ID, data or various error conditions

The protocol-specific trigger lets you reliably isolate protocol events and errors. Thanks to high acquisition rates, Rohde & Schwarz oscilloscopes are ideal for finding errors quickly, allowing decoding of protocol-specific trigger results. The hardware-based triggering is available on specific protocol content, e.g. addresses, data and protocol errors.

Search and navigate in recorded acquisitions

Powerful search and navigate capability

Comprehensive search functions simplify the analysis of long signal sequences. You can search for waveforms based on different criteria, such as signal faults or protocol content. All detected events are shown in a table with timestamps. The individual events can be examined in a zoom window with simple navigation between events.
