Real-Time Automated Residual Phase Noise Measurements to 50GHz
June 7, 2022
Measuring phase noise is becoming more commonplace as a key method for quantifying signal stability. Residual/additive phase noise measurements are of the most error-prone phase noise measurement setups, especially at higher frequencies.
Phase Noise Analysis has traditionally been a smaller sector of the electronics test and measurement market, primarily being a parameter that was verified by defense radar systems providers. With the rapid growth of high-speed communications markets, everyone from chipset manufacturers to complete systems providers have been adopting phase noise as the key parameter for quantifying RF signal stability performance. Furthermore, phase noise can be quickly converted to jitter, enabling a reliable method for rapid jitter analysis for time domain applications.
This application note discusses the immunity of the RAA78815x family of RS-485/RS-422 transceivers to repetitive Electrical Fast Transients (EFT) as defined in IEC61000-4-4. It...
