TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

Field Probe Correction Factors
To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.
Verifying The Clock Source
In order to select or develop a clock generator to use in your design or to ensure that the supplied system clock has the proper performance, you'll need to consider phase noise, jitter, wideband noise and spurs as performance indicators.
What Is Pulse Shaping?
In this industry briefing,George Bollendorf explains a new approach to fix fidelity issues caused by the transmitting amplifier that matches input pulse signal shape, minimizes droop, overshoot, ringing, and rise and fall times.
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.
Simplify Coexistence And Interference Testing For GNSS Receivers
The R&S®SMW200A GNSS simulator offers an easy and convenient way to test your receiver design against a wide variety of potential interferers and jammers. Test cases extend from simple coexistence simulations to complex interference scenarios with localized emitters.

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.
