Rohde & Schwarz to Present T&M Solutions for Power at PCIM Europe 2019

May 1, 2019 Alix Paultre

Rohde & Schwarz will present its family of oscilloscopes and power supplies for power electronics applications at PCIM Europe International Exhibition and Conference from May 7 to 9, 2019, in Nuremberg. Highlights include high-sensitivity oscilloscopes with fast FFT functionality for EMI debugging in fast switching applications, as well as Bode plot functionality integrated into oscilloscopes for control loop stability testing. Under the banner "Three tasks in one device," Rohde & Schwarz will display the R&S RTM3000 and R&S RTA4000 oscilloscopes, each of them focusing on three important application areas concerning power electronics design.

The R&S RTM3000 and R&S RTA4000 can correlate electromagnetic emissions in the frequency domain with the corresponding signals in the time domain, allowing a deeper insight into the root-cause of unwanted emissions. This helps developers minimize unwanted EMI from switched-mode power supplies right on the lab bench. The R&S RT-ZHD high-voltage differential probe family and the R&S RT-ZD10 broadband differential probe enable accurate analysis of the switching operation in power electronics designs. Both the R&S RTM3000 and R&S RTA4000 offer 10-bit vertical resolution and memory allowing longer periods of time to be captured at full bandwidth.

The R&S RTx-K36 Bode plot option for the R&S RTB2000, R&S RTM3000 and R&S RTA4000 oscilloscopes enables control loop stability tests on switched-mode power supplies without the need for separate test equipment. In addition, it allows the characterization of filters and amplifier circuits as well as measuring the power supply rejection ratio (PSRR). The option uses the oscilloscope's built-in waveform generator to create stimulus signals for the DUT. It displays the results as a Bode plot or in a table.

Other instruments on display at the Rohde & Schwarz booth are the R&S NGL200 power supply and the R&S Scope Rider. The new R&S NGL200 power supply series was designed specifically for challenging applications that require high accuracy and fast load recovery times. The R&S Scope Rider is a handheld oscilloscope with up to four isolated input channels with CAT IV 600 V / CAT III 1000 V rating offering lab performance in a portable design.

Rohde & Schwarz can be found in hall 6 (booth 246) at the PCIM Europe International Exhibition and Conference from May 7 to 9, 2019, in Nuremberg.
