New Differential Probe and Customer-Requested Features For Tektronix Oscilloscopes Boost Productivity, Simplify Analysis

2/20/2003 - Tektronix, Inc. (NYSE: TEK), the world's leading manufacturer of oscilloscopes for design, manufacturing, and service applications, announced multiple oscilloscope productivity enhancements and features aimed at the latest technology advancements in high-performance digital systems and devices.

Today's advanced digital design applications need tools that improve the efficiency of critical measurement tasks, such as serial bus conformance testing or signal integrity troubleshooting. Now, significant functional enhancements for Tektronix' TDS7000 Series, CSA7000 Series, and TDS6000 Series oscilloscopes-plus the P7350 5-GHz differential probe-are available to address these measurement challenges. Among the enhancements are internal system serial bus masks (which join an already broad selection of masks to round out the industry's most complete mask test solution), the innovative MultiView zoom feature, increased base record length, and more. These capabilities will improve designers' measurement accuracy and productivity, while saving valuable time during the design process.

"Our oscilloscopes have consistently delivered more than industry-leading bandwidth to enable advancements in digital system performance," said Colin Shepard, Vice President, Oscilloscope Products, Tektronix, Inc. "With this package of enhancements, designers gain powerful features like internal system serial bus masks to help them assess their designs quickly, troubleshoot, and solve problems early in the process. And, the P7350 probe provides the most faithful acquisition of high-speed differential signals, ensuring an accurate basis for analysis."

Growing Complexity Joins High Data Rates To Challenge Measurement Tools
The constant demand for increased data throughput in digital systems and devices has brought about two trends that mark today's computer, communications, and integrated circuit technologies: First, a steady increase in clock/data rates, and second, a growing reliance on serial buses for data transmission within systems. Sensitive high-speed differential bus signals require specialized probing solutions. Complex serial protocols elude conventional waveform viewing, requiring instead accepted measurement techniques, known as "masks" that outline appropriate signal limits. To fit within a mask, a signal must have appropriate amplitude, risetime, falltime, overshoot, ringing, and jitter. These, and many other measurement challenges, require tools that do more than just meet bandwidth needs. Tools must also save time and improve designers' ability to speed their research, concept validation, prototype evaluation, and troubleshooting.

Digital Design Challenges Meet Their Match
The enhancements for the TDS7000, CSA7000, and TDS6000 Series oscilloscopes increase the value and versatility of these proven instruments and the productivity of their users. All models in these three series are now shipping with the Windows‚ 2000 operating system installed, for improved usability and compatibility with engineering networks. Engineers developing routers, hubs, and other telecom and datacom elements will benefit from the thirty masks for serial communication standards, such as PCI-Express, RapidIO, SPI/SFI-5, and more. These masks join an existing selection of masks to create the industry's most complete solution for serial bus physical-layer testing.

A dual-axis screen cursor function eases the correct positioning of the cursors on the waveform for fast and easy measurement of voltage, timing, or edge-to-edge measurements. This feature speeds the troubleshooting work of digital designers who routinely must determine exactly when a device receives a valid logic threshold.

Designers of disk drives (among other applications) will save time with MultiView zoom. As a set of record management tools, including Zoom-on-Zoom, Align-Lock-Scroll, and Rapid Navigation, MultiView zoom enables users to find specific events in a long record quickly, visually compare them with other events, align them, lock them together, automatically scroll through the entire waveform record, and more. Using this feature, engineers can quickly home in on localized signal integrity problems, for example, then easily find other repetitions or variations elsewhere in the acquisition.

Other new features include measurement annotation, which displays markers and measurement information on the waveform to indicate where measurements were made, ensuring high-confidence results. The X-Y display format, once available only in DPO-based oscilloscopes such as the TDS7000 Series, now comes to the TDS6000 Series DSO for efficient power measurements and constellation displays. Finally, the base record length of the TDS/CSA7000 Series oscilloscopes has been increased from 400 KB to 2 MB.

Expanding Leadership With The P7350 Differential Probe
Incorporating nine patents with three additional patents pending, the P7350 is a companion to the world's fastest single-ended active probe, Tektronix' 6 GHz P7260. With 5 GHz bandwidth, it is the world's only available differential probe with bandwidth beyond 3.5 GHz (P7330). And, it meets stringent requirements for accurately measuring signals (as found in RapidIO, for example) at data rates up to 2.5 gigabits per second (Gb/s). Additionally, its fast risetime (guaranteed at <100 picoseconds (ps) (10% to 90%)) and low loading are well matched to the challenges of compliance testing and design validation. Compatible with Tektronix oscilloscopes in the TDS6000, TDS7000, and CSA7000 Series, the P7350 is also fully integrated into the measurement system via the patented TekConnectš interface. Finally, variable spacing and solder-in capabilities enhance its usability.
