Key facts

  • Supports decoding of USB-SSIC gear 1 and 2 signals
  • Reliable triggering on 35 different frame types, frame content and various errors conditions
  • Display of all decoded packets as color-coded bus signals as well as in tabular format
  • On-screen serial decoding is time-correlated with the waveform
  • Powerful search and navigate capability for 35 different frame types, frame content and various errors conditions
  • R&S oscilloscopes | Engineered for multi-domain challenges

Oscilloscope software

The R&S®RTO oscilloscopes enable debugging of USB-SSIC interfaces (gear 1 and 2). 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 efficiently and reliably. You can trigger on 35 different frame types, frame content and various errors 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 telegrams can also be displayed in a concise table.

Decoded frames are color-coded

Strong trigger capability

Strong trigger capability on start, stop, address, data and 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.
