Rohde & Schwarz presents its full range of embedded systems test solutions at embedded world 2022

Rohde & Schwarz presents its full range of embedded systems test solutions at embedded world 2022 Nuremberg will be home to the international embedded industry once again during embedded world Exhibition & Conference. Rohde & Schwarz will be showing its latest test solutions from June 21 to 23, 2022 at booth 4-218 of Nuremberg Exhibition Centre. There, visitors can experience product highlights like the new generation of the R&S RTP high-performance oscilloscope, and they can learn from the Rohde & Schwarz experts about state-of-the art test solutions for all kinds of embedded systems.

Rohde & Schwarz addresses numerous applications for the wider embedded industry with its test equipment. At embedded world, the company will demonstrate test solutions for high-speed digital interfaces, signal and power integrity, embedded power systems and EMC debugging. Visitors can also learn about physical layer testing for common internet of things (IoT) technologies. And selected solutions for the automotive industry are on display as well.

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 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. The TDR/TDT software includes a wizard that guides the user through setup, calibration and analysis. Another setup will show compliance and debugging measurements of an HDMI 2.1 cable. 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.

Verifying embedded power systems

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 to quickly see infrequent ripple as well as periodic and random disturbance (PARD) anomalies. Part of the setup is the R&S RT-ZPR, an excellent oscilloscope probe for characterizing power rails with its high bandwidth, high sensitivity, very low noise and an extra-large offset compensation.

Another recent addition to the Rohde & Schwarz portfolio on display at embedded world is the R&S LCX LCR meter, a high-performance general-purpose impedance tester for a wide range of applications. The R&S LCX200 measures inductance (L), capacitance (C) and resistance (R) of components within the supported frequency range from 4 Hz to 10 MHz. In combination with an external sweep tool, users can measure the impedance curve over frequency of an electrolytic component. Other parameters like test voltage or test current can be used as sweep parameter.

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

EMC debugging

EMC compliance turns into a challenge, for example with increasing switching speed in power electronics, which involves the risk of higher electromagnetic interference (EMI). Detecting design problems early makes correction easier and more cost effective. As a leader in EMC testing Rohde & Schwarz offers the full spectrum, from EMI debugging and precompliance test solutions to full EMC compliance test systems. At embedded world, Rohde & Schwarz demonstrates solutions that easily integrate EMI testing into the product development process - from oscilloscopes as powerful tools for EMI debugging to signal and spectrum analyzers for precompliance testing.

The R&S RTO6 oscilloscopes with its high dynamic range and input sensitivity of 1 mV/div at full measurement bandwidth makes it possible to detect even weak emissions. Its powerful FFT capabilities are ideal for EMI analysis in the frequency domain thanks to their easy operation, high acquisition rate and manifold functions, such as color coding of the spectral display according to frequency of occurrence. The zone trigger in the FFT is ideal for detecting sporadic emission frequencies.

The R&S FPL1000 signal and spectrum analyzer, which combines the functions of a benchtop instrument with the portability of a handheld instrument, also offers EMI precompliance measurements when equipped with the option EMI Measurement Application K54. The features include EMI detectors such as peak, quasi-peak, CISPR-average and RMS-average (CISPR 16-1-1) and 6 dB filter characteristic (CISPR 16-1-1 and MIL-STD-461 / DO-160). Fast, easy-to-read diagnostic measurements provide results with high reproducibility. For automated certification and precompliance tests Rohde & Schwarz is also showing its R&S ELEKTRA EMC test software. The software is available in several versions: with interactive test sequences for developers or as fully automatic EMC test software for device certification.
