The power electronics community will meet again at PCIM Europe in Nuremberg from 10 to 12 May 2022. Rohde & Schwarz joins to demonstrate its latest test solutions for developers of power supplies and other power electronics. The company’s experts share their know-how on applications such as stability analysis, power integrity and component testing, as well as EMI troubleshooting and EMI pre-compliance testing at Rohde & Schwarz booth 452 in Hall 7.

Rohde & Schwarz test solutions address a wide range of power electronics design challenges. At PCIM Europe, visitors can test test equipment such as the recently introduced R&S RTO6 oscilloscope, which performs stability analysis and power integrity measurements.

When debugging and validating power rails, it is essential to ensure that power supply integrity requirements are met. The inherent low noise of the R&S RTO6 oscilloscopes allows accurate measurements of power integrity at the millivolt level. The fast update rate of the oscilloscope allows you to quickly see rare pulsations, as well as periodic and random disturbances (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 extremely high displacement compensation.

Another recent addition to Rohde & Schwarz’s portfolio is the R&S LCX LCR meter, a high-performance general-purpose impedance tester for a wide range of applications. The PCIM displays the R&S LCX200, which measures the inductance (L), capacitance (C) and resistance (R) of the components within the maintained frequency range of 4 Hz to 10 MHz. In combination with an external cleaning tool, users can conveniently measure the impedance against the frequency of an electrolyte component. Other parameters, such as test voltage or test current, can be used as oscillation parameters.

Increasing the switching speed in power electronics involves the risk of higher electromagnetic interference (EMI), making EMC compliance a challenge. Early detection of design problems makes correction easier and more cost-effective. Rohde & Schwarz demonstrates PCIM solutions that easily integrate EMI testing into the power product development process, from oscilloscopes as powerful EMI debugging tools to signal analyzers and spectrum for pre-compliance testing.

R&S RTO6 oscilloscopes with their high dynamic range and input sensitivity of 1 mV / div at full measurement bandwidth make it possible to detect even low emissions. They offer powerful FFT capabilities that are ideal for EMI frequency domain analysis thanks to their easy operation, high acquisition speed and many features such as color coding of the spectral display according to the frequency of occurrence. The unique zone trigger in FFT is ideal for detecting sporadic emission frequencies.

The R&S FPL1000 signal and spectrum analyzer, which combines desktop instrument functions with handheld portability, also offers EMI pre-compliance measurements when equipped with the optional EMI R&S FPL1 K54 measurement application. 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 high reproducibility results.

For automated certification and pre-compliance testing, Rohde & Schwarz is also showcasing its R&S ELEKTRA EMC testing software. The software is available in several versions: with interactive test sequences for developers or as fully automatic EMC testing software for device certification.

Visitors can find Rohde & Schwarz in Hall 7, Stand 452 of the PCIM Europe International Exhibition and Conference from 10 to 12 May 2022 in Nuremberg. For more information on T&M power electronics solutions from Rohde & Schwarz, click here.
