Scopes cover hi-speed/hi-fidelity domains at ESC News & Analysis 8/30/2011 1 comment Tektronix, Inc. has introduced a mixed-domain oscilloscope that delivers the functionality of an scope and a spectrum analyzer in a single instrument. And Rohde & Schwarz has enhanced its real-time digital trigger scope for analyzing extremely small signals with high fidelity. Both companies will exhibit their wares at the Embedded Systems Conference, Boston (Sept. 26 to 29).
Measuring leakage current in RF power transistors Design How-To 8/29/2011 5 comments Around the globe, engineers and technicians using RF power devices have had many concerns regarding the specifications for leakage current, what the specifications mean in terms of the part’s performance in the field, and most importantly, how to properly test/verify that a given part is meeting its printed leakage current specification…

Hall effect measurements in materials characterization Design How-To 8/17/2011 Post a comment This article addresses how Hall effect measurements are used in materials characterization, trends in the semiconductor industry that drive the need for making these measurements, and factors to consider when selecting measurement instrumentation.
Answering the consumer market’s demand for non-volatile memory Design How-To 8/10/2011 1 comment Non-volatile memory requires substantial R&D investment in terms of both human resources and characterization tools to help them evolve. This is an area in which consumer products manufacturers and their vendors must continue to invest if they are to compete globally.
Measurement accuracy/signal integrity prove king of banner specs Design How-To 8/1/2011 Post a comment The relentless pursuit of speed and capacity across the electronics industry is changing the rules for high-end oscilloscopes. While bandwidth used to be the “banner spec” that customers and vendors focused on when evaluating oscilloscopes, the level of precision required to capture and analyze today’s fastest serial and optical signals means measurement accuracy or signal integrity has now emerged as the most important factor.
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.
