TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• AC-DC Converter Testing Fundamentals

  AC-DC conversion stage in front of any electronic equipment is needed. For this purpose, different solutions exist to convert the higher AC voltage to a lower and safe DC voltage.

• Solution For BCI Applications

  Rohde & Schwarz provides a compact solution for conducted immunity tests with a signal generator, RF solid-state amplifier up to 350 W, power sensors, and test software for frequencies from 4 kHz to 400 MHz.

• Design And Implementation Of A Miniature X-Band Edge-Coupled Microstrip Bandpass Filter

  Microwave bandpass filters are the fundamental component used in many RF/microwave applications to eliminate interference from signals operating at nearby frequencies. This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator within Cadence AWR Design Environment software.

• Directivity And VSWR Measurements: Understanding Return Loss Measurements

  The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

• Ensuring Test Site Compliance for Radiated Emissions With Normalized Site Attenuation

  This application note provides a synopsis of Normalized Site Attenuation (NSA) and Reference Site Method measurements which indicate a challenging but important aspect of radiated emissions measurements on an OATS, SAC, or FAR.
