Rohde & Schwarz to present embedded systems test solutions at embedded world 2022

09 June 2022

Rohde & Schwarz will be showcasing its latest test solutions at embedded world 2022, scheduled for June 21 to 23, 2022, at booth 4-218 of the Nuremberg Exhibition Centre in Germany. Test solutions for high-speed digital interfaces, signal and power integrity, embedded power systems and EMC debugging will be demonstrated at the event, where visitors can also learn about physical layer testing for common internet of things (IoT) technologies.

One highlight at the Rohde & Schwarz booth is the new generation of the R&S RTP high-performance oscilloscope, which combines high-class signal integrity measurements with fastest acquisition for real-time analysis. The new models of the most compact instruments of its class come equipped with a bigger and brighter 13.3-inch full HD touchscreen and a fully redesigned front panel. At embedded world, a 16 GHz bandwidth model of the R&S RTP will be on display performing time domain reflection (TDR) and transmission (TDT) analysis, which supports the characterization and debugging of signal paths, including PCB traces, cables and connectors.

Utilizing the R&S ScopeSuite Compliance Test framework, the R&S RTP executes automated tests with image-based guidelines and summarizes results in a test report for various high-speed digital interfaces.

A crucial aspect when designing embedded systems is power supply and its implications. Rohde & Schwarz will bring selected solutions to embedded world that address this application field. When debugging and validating power rails, for instance, it is essential to ensure that power integrity requirements are met. The inherent low noise of the recently introduced R&S RTO6 oscilloscopes enables accurate power integrity measurements at the millivolt level. The fast update rate of the oscilloscope allows users to quickly see infrequent ripple as well as periodic and random disturbance anomalies. Part of the setup is the R&S RT-ZPR, an oscilloscope probe for characterizing power rails with its high bandwidth, high sensitivity, very low noise and an extra-large offset compensation.

For power consumption testing of any battery-operated device, especially IoT equipment with very low sleep currents, the two-quadrant R&S NGU201 source measure unit will be on exhibit. Design engineers can use this specialty power supply to simulate real-world battery characteristics.

For an ever-increasing range of in-vehicle networks, the simple unshielded twisted-pair network technology of automotive Ethernet provides a flexible solution. The R&S RTP high-performance oscilloscope provides a fast and efficient means to verify, commission and troubleshoot designs based on an automotive Ethernet communication link of various standards, from today’s 1000BASE-T1 to tomorrow’s MultiGigabit. The instrument not only measures and verifies compliance to the standards but also decodes the messages and reliably triggers on them.
