A simple oscilloscope setup can size common-mode and differential-mode noise filtering components separately and more accurately. Marcus Sonst, Rohde & Schwarz Any switched-mode power supply (SMPS) needs an EMI (electromagnetic interference) input filter to avoid disturbing power lines. Input filters generally contain both common-mode and differential-mode filter elements, and the two are rarely optimized separately. […]

Measure power in complex RF signals
IMS2021: Live event was never in doubt
While the International Microwave Symposium will also hold a virtual conference, exhibitors insisted on a live event albeit with COVID-19 restrictions.
UWB test gear characterizes angle of arrival, phase difference of arrival
Engineers testing UWB devices now can combine the R&S CMP200 radio communication tester and WMT software service to implement automated wireless manufacturing testing from Rohde & Schwarz with the high-precision delay lines XT-200 from Colby Instruments to perform measurements in conducted mode including calibration and verification. In UWB technology, the distance between two devices is […]
DSS lets 5G and LTE share spectrum
Dynamic spectrum sharing of 5G and LTE networks addresses the need for spectrum, particularly at mid-band frequencies. Here’s how it works.
Benchtop linear power supplies come in single and dual-channel versions
New R&S NGA100 series power supplies are available in four models, providing a choice of single and dual outputs with up to 35 V/6 A per output, or 100 V/2 A per output. Single-output models supply up to 40 W, dual output models up to 80 W power. The dual model outputs can be combined […]
Calibration method improves 5G base station test accuracy
Rohde & Schwarz updates R&S PWC200 to provide better accuracy and wider frequency range in 5G FR1 base station OTA testing.
Scope test setup complies with IEEE 802.3ch MultiGBASE-T1 Automotive Ethernet standard
The new K88 option for R&S RTO and R&S RTP oscilloscopes from Rohde & Schwarz enables compliance testing on the next evolution of the automotive Ethernet standard. The new IEEE 802.3ch standard addresses the need for high speed networking and data transfers within the car. With the K88 software option, Rohde & Schwarz continues to […]
Vector network analyzers feature up to 67 GHz frequency range
The R&S ZNA newly introduced models cover frequency ranges of up to 50 GHz and 67 GHz. The R&S ZNA features excellent RF performance, including wide dynamic range and extremely low trace noise, and comes with a user-friendly, purely touch based GUI. Its unique hardware platform offers up to four internal, phase coherent sources plus […]
Source measurement units reliably gauge currents from nanoamps to amps in a single sweep
The R&S NGU series of high-precision SMUs feature innovative current feedback amplifier technology that provides both maximum sensitivity and accuracy to reliably measure currents from nanoamps to amps in a single sweep. To handle rapidly changing load conditions typical of battery-powered communications devices switching between sleep and transmit modes, the R&S NGU features an optimized control loop […]
