Key facts

  • The protocol frame can be configured, including preamble, frame ID, data, CRC and more
  • Display of all decoded telegrams as color-coded bus signals or in tabular form, as defined in the frame configuration
  • Triggering on start of frame, frame ID and data. Maximum data rate for triggering of 50 Mbit/s
  • Support of up to 50 different frame formats
  • Fastest eye-diagram mask testing with standard mask test functionality
  • R&S oscilloscopes | Engineered for multi-domain challenges

Oscilloscope software

The R&S®RTO and R&S®RTE oscilloscopes support triggering and decoding of any Manchester and NRZ coded serial protocol with data rates up to 5 Gbit/s, including Manchester violation detection. You can define up to 50 different frame formats. Errors are identified reliably and efficently using the hardware-accelerated trigger. You can trigger on start of frame, frame ID and data.

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.

Up to 50 different frame formats

Frame formats for NRZ and Manchester buses

You can define up to 50 different frame formats for any NRZ or Manchester coded protocol with data rates up to 5 Gbit/s.

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.

Strong trigger capability

Strong trigger capability on start of frame, frame ID and data

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.

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.

Powerful searching, even in long recordings.
