Agilent Digitizing Oscilloscope Selected by Rambus for Measuring RIMM Module Signal Integrity.PALO ALTO, Calif.--(BUSINESS WIRE)--Nov. 2, 1999-- Time Domain Reflectometry with Normalization In relational database management, a process that breaks down data into record groups for efficient processing. There are six stages. By the third stage (third normal form), data are identified only by the key field in their record.

Displays of such nonelectrical phenomena as the variations of a sound's intensity can be made if the phenomena are for measuring signal integrity on Rambus-based motherboards and RIMM (Rambus Inline Memory Module) See RDRAM. See also RIM. (TM) (Rambus Inline Memory Module) Module printed circuit boards (PCBs). The Agilent 54750 oscilloscope with time domain reflectometry (TDR TDR - time domain reflectometer ) provides highly accurate impedance measurements of 28-ohm Rambus-based PCBs by using a technique called normalization. With this very precise and highly innovative measurement technique, circuit-board traces as short as one inch can be characterized. "The Agilent 54750 oscilloscope's ability to accurately measure 28-ohm impedance makes it a valuable tool to PCB PCB: see polychlorinated biphenyl. PCB in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. , motherboard and RIMM Module makers," said Laura Fleming, director, Alliances and Infrastructure, Computer and Memory Group, Rambus Inc. "Rambus' memory architecture is a trailblazer in the future of high-speed memory, and its 28-ohm characteristic impedance measurement can be handled with ease using our digitizing oscilloscope," said Werner Huettemann, general manager of Agilent's Lightwave Division. HP announced its entry into the high-speed memory test market last fall with the introduction of a high-speed memory test series for production testing of high-bandwidth dynamic random access memory Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. (DRAM). At the end of 1998, HP also introduced an analysis probe for use with its most advanced logic analyzers in monitoring bus transactions from a host computer to the Direct Rambus(TM) memory subsystem. About the TDR Normalization Technique The TDR normalization technique is based on an algorithm embedded in the Agilent 54750A's firmware. The technique is based on the Bracewell Transform, a digital error-correction algorithm that was originally licensed from Stanford University. This normalization technique removes errors created by test fixtures and probing equipment, therefore making it easier to measure precisely to the +/-2.8-ohm Rambus tolerance specification.
