Key facts

  • Decoding and triggering of low power (LP) and high speed (HS) parts
  • Display of decoded telegrams as color-coded honeycomb in the waveform diagram or in tabular format
  • Decoding using fixed clock speed or direct clock measurement
  • Decoding on the needed level: starting from edges, over lanes to merged data stream
  • Fully integrated in the GUI
  • R&S oscilloscopes | Engineered for multi-domain challenges

Oscilloscope software

The R&S®RTO oscilloscope supports triggering and decoding of MIPI D-PHY based protocols DSI and CSI-2. You can set up decoding in seconds. For analysis, results can be viewed as color-coded telegrams and in a table. Errors are identified using the hardware-accelerated trigger. You can trigger on HS start of packet, HS end of packet, HS packet header, HS data, LP escape mode, LP lane turnaround, LP HS request and various error conditions.

Features & benefits

Fast bus setup

Bus setup in seconds starting from 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.

Configuration of D-PHY decoding for 4 channels.

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.

Strong trigger capability

Trigger on HS start of packet, HS end of packet, HS packet header, HS data, LP escape mode, LP lane turnaround, LP HS request

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.
