VSWR Conversion To Reflected Power
VSWR measures how efficiently RF power is transmitted through a load, with high VSWR indicating poor efficiency. Explore VSWR's relation to return loss, reflection coefficient, and mismatch loss.
How To Analyze Passive Low Frequency Components With A Rohde & Schwarz Oscilloscope
This white paper presents a technique for easily and quickly analyzing low frequency response on an oscilloscope with the R&S®RTx-K36 frequency response analysis (Bode plot) option, which uses the oscilloscope’s built-in waveform generator to create stimulus signals ranging from 10 Hz to 25 MHz.
Effortless Testing Of Direction Finding Devices – Amplitude Based
Together with multiple coupled R&S SMW200A vector signal generators, the R&S Pulse Sequencer allows performance characterization of all types of direction finding equipment such as devices that use amplitude comparison, interferometric or time difference of arrival (TDOA) techniques.
Testing A 24-28GHz Power Amplifier Using The 5G New Radio Test Standard
In this white paper, we will introduce some of the main challenges in test and measurement of a device at mmWave frequencies, with a 26 GHz pioneer band defined for the UK between 24.25 - 27.5 GHz.
Transmit And Receive Testing Of Digital Waveforms Using R&S®CMA180
The compact R&S®CMA180 Radio Test Set allows straightforward tests on devices that use analog or digital modulation and demodulation formats. This application note focuses on the use of the digital radio capabilities for measurements on radio transceiving devices in terms of their functionality and parameter characterization. Also shown is how to use the instrument with the various software tools available from Rohde & Schwarz for creating and evaluating digitally modulated signals.

Electrostatic Discharge (ESD) Testing Simulation

Electrostatic discharge testing is utilized worldwide by electronics manufacturers to determine the ESD susceptibility of their devices. It is extremely difficult to estimate the exact cost of ESD loss annually, but it can safely be stated that ESD requires the development and testing of many hardware prototypes and contributes to a high number of warranty claims and loss of consumer confidence if failure occurs in the hands of the customer. Given the high cost in time and materials associated with ESD hardware testing, the ability to simulate the ESD testing process in XFdtd is extremely valuable, allowing engineers to pinpoint locations susceptible to ESD damage and optimize ESD mitigation during the concept and design stage of product development.

TWT Amplifier: dB-3906

The dB-3906 TWT Amplifier (TWTA) is designed to use two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. The dB-3906 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.
