Increasing data rates in high-speed digital designs and wireless communications require SerDes PLLs and clock synthesizers with low additive phase noise and high jitter attenuation. Modern designs often follow a two-stage architecture comprising a jitter-attenuator and a frequency-synthesizer stage. 

Spectrum View is a new tool for performing spectrum analysis on an oscilloscope. This application note demonstrates how Spectrum View operates and how it differs from traditional oscilloscope FFT functions.

This article on passive intermodulation by HUBER+SUHNER defines passive intermodulation (PIM), discusses why PIM is a problem, what causes it, what to do to combat it, and what must be considered when using low-PIM products.

A complex testing scheme usually involves integrating multiple pieces of equipment from multiple manufacturers. This article discusses the differences in proprietary and generic interfaces, the benefits each type has to offer, and offers some solutions to potential interface barriers and how to remove them.

Early standardizations were focused on the hardware abstraction, but modern technology relies mostly on the software. Test organizations must move now move to standardized methods of iterative software development to remain competitive in the market.

The process of evaluating the performance of ultra-low-phase noise oscillators requires phase noise test systems with lower measurement times, lower noise floor capabilities, and high reliability and repeatability of test data.

By using a performance EMI receiver, independent compliance test laboratories and companies with in-house self-certification labs can make radiated and conducted emissions tests, certifying a product meets local regulatory compliance standards. 

The AR Catalog for RF and EMC testing features Universal “U” series amplifiers with the widest bandwidth in the industry, covering the 10 kHz to 1000 MHz frequency range and up to 25 watts CW. Applications for these amplifiers include lab use, R&D, EMC testing, antenna testing, and watt meter calibration.

Designing RF switching systems can be dull, so the importance of designing one is often overlooked. However, designing a proper switching system is essential to the operation of the rest of the testing system, so it is vital to make the right choices for a successful automation. 

Charles Tumbaga of Anritsu introduces their new Extended-K components, ideal for getting traceable and mode-free measurements up to 43.5 GHz.

XFdtd Electromagnetic Simulation Software simulates electrostatic discharge (ESD) testing, enabling engineers to identify potential locations of dielectric breakdown and components at risk of damage in their device designs. In this webinar, Remcom will introduce XF’s collection of ESD simulation features and demonstrate how to minimize the chance of undetected damage prior to hardware testing.

Antenna efficiency plays a critical role in overall smartphone RF performance. Aperture tuning is one technique available to mobile designers to optimize the antenna, but implementing it requires in-depth knowledge. Qorvo has written a new resource, How to Implement Aperture Tuning: Best Practices for 4G/5G Smartphones, to help you learn more.
