Oscilloscope software

All Rohde & Schwarz oscilloscopes can help trigger and decode I2C, as well as 2-wire, 3-wire and 4-wire SPI buses. The same is true for UART, RS-232, RS-422 and RS-485 buses. Custom decode is also included for any Manchester and NRZ coded serial protocol with data rates of up to 5 Gbit/s and Manchester violation detection. Furthermode, R&S®RTO6 oscilloscopes can cover trigger and decode on I²S audio standard, left and right justified and TDM signals.
You can set up decoding in seconds. For detailed analysis, results can be viewed as color-coded frames as a protocol decode overlay and/or in a table. Errors are identified efficiently and reliably with the hardware-accelerated trigger. You can trigger on start, stop, address, data and various error conditions.

Features & benefits

Fast bus setup

Bus setup in seconds with the app cockpit
 

From the app cockpit, any protocol can be configured in only a few steps. Once you choose the bus to be decoded, select the connected channels and set the correct levels, decoding begins automatically.

Color coded protocol decode overlay display

Protocol decode overlay display as color-coded frames on waveforms and listed in a 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 and ASCII format. Flexible screen setup ensures that you always have an excellent overview. The colored frames of the protocol decode overlay can also be displayed in a concise table.

Stronger trigger capability

Strong trigger capability for start, stop, address, data and various error conditions
 

The protocol-specific trigger lets you reliably isolate protocol events and errors. High acquisition rates make Rohde & Schwarz oscilloscopes ideal for finding errors quickly. Protocol-specific trigger results can then be decoded.

Search and navigate in recorded acquisitions

Powerful search and navigation capabilities
 

Comprehensive search functions simplify analysis of long signal sequences. Search for waveforms based on various criteria such as signal faults and 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.
