8/28/2002 - Tektronix, the world's leading manufacturer of oscilloscopes, announced a new software option that enhances oscilloscope capabilities to provide optical storage designers with unprecedented customization and automation.
Designers developing next-generation optical storage systems, particularly those based on Compact Disk (CD) and Digital Video Disk (DVD) formats, must continually increase drive performance to compete in the marketplace. The current tools available to make optical storage measurements lack important display and analysis features, and are not equipped to handle the more advanced requirements of new architectures/designs. The Tektronix TDSDVD optical storage analysis software transforms the award-winning TDS5000 and TDS/CSA7000 Series digital phosphor oscilloscopes (DPOs) into efficient measurement tools with innovative industry-specific features for CD/ DVD development. With its TekFlexTM feature, this software is the first tool to give designers the ability to configure custom digital signal processing (DSP) blocks to substitute the standard blocks in the CD/ DVD architecture.
"The new TDSDVD software package gives engineers tools specifically aimed at CD/DVD development, including the TekFlex plug-in capability, not found on any other measurement platform, said Colin Shepard, Vice President, Oscilloscope Products, Tektronix, Inc. "This product demonstrates Tektronix' commitment to meeting the needs of our customers designing products that enable emerging technologies, such as high-capacity optical storage."
New DVD Technologies Pursue Higher Density
Designers in the optical storage industry are today developing technologies that will provide higher capacity at lower cost. Typically these efforts fall into two general categories: first, the implementation of breakthrough technologies such as the blue laser diode, known as Blu-Ray, to support new DVD drives that deliver dramatically increased data storage capacity. Secondly, the development of new chipsets that can enhance and differentiate existing optical storage products, with a goal of gaining competitive advantage. Although these standards are just emerging, flexibility has been designed into the software to support their advancement.
The two applications share many measurement needs, including a requirement for easy-to-use industry-specific amplitude and timing tests; time interval analysis; signal processing features; and the ability to accurately display high-frequency "eye" diagrams. In addition, each application has specific needs related to bandwidth, record length, price, and more.
Industry-Specific Tools Join Proven DPOs, Pace Advancing DVD Performance
The TDSDVD optical storage analysis software combines the capabilities of an analog oscilloscope, digital oscilloscope, and jitter analyzer into one simple-to-use tool that provides complete system characterization and allows designers to maximize the performance of existing systems and next-generation designs.
Because of their fast signal speeds and complexity, these new designs are outgrowing what analog oscilloscopes, commonly used for this job, can handle. Both the TDS7000 and TDS5000 Series instruments provide the needed capability in a powerful digitizing instrument. Paired with the TDSDVD package, these tools offer capabilities such as a lively display showing rich signal detailing, processing power and advanced analysis, which allow designers to examine critical eye diagrams and quickly assess the performance of their designs.
The TDSDVD package provides a full series of conformance measurements to ECMA (European Computer Manufacturers Association) standards. These include amplitude characteristics such as asymmetry, timing parameters such as jitter and edge-shift considerations due to inter-symbol interference, and more. Preset measurement values can be modified to evaluate prototypes and stress-test new concepts.
The unique TekFlex feature, a standard part of the TDSDVD package, allows designers to configure custom digital signal processing (DSP) blocks to substitute for standard blocks in the DVD architecture. Variations on a particular block can be substituted for standard elements, allowing engineers to apply a change and measure its effect with the same tool. The TekFlex feature is indispensable for next-generation DVD and chipset designers, who may need to explore many proprietary DSP functions to arrive at a distinctive competitive feature. The TDSDVD TekFlex feature, working with the industry-specific measurement set, provides fast answers to engineers working under tremendous time-to-market pressure. In an emerging market with unresolved standards, TekFlex allows the measurement tool to adapt as new technical needs evolve.
The TDSDVD package also includes a built-in Time Interval Analyzer (TIA) display feature. Designers will rely on this display to obtain more insight into the signal characteristics. The TDSDVD optical storage analysis package consists of software that is user-installed in TDS7000 and TDS5000 DPO oscilloscopes using conventional Windows® install procedures. The tools run on the instruments' Windows operating system.
