Understanding RF Instrument Specifications: Part 2 Design How-To 8/8/2007 1 comment This is the second of a three-part article series on RF instrument fundamentals from National Instruments. This article covers five specifications that are particularly important to RF signal generators: frequency tolerance, output level accuracy, output power range, intermodulation distortion, and modulation bandwidth.
PLL analyzer tests for PCIe compliance Product News 8/6/2007 Post a comment SyntheSys Research has released its BERTScope PLA series of phase locked loop (PLL) analyzers for PLL loop response characterization and compliance testing to PCIe specifications for components and add-in cards.
Using model-based design in signal integrity engineering Design How-To 8/1/2007 Post a comment RF techniques, originally developed for wireless communication projects, are being repurposed to solve the increasingly complex problem of preserving signal integrity in high-speed data transmission between chips joined by backplanes and printed circuit boards.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
