7-GHz DPO/Communications Analyzer Addresses Serial Data Buses

The real-time TDS7704B digital phosphor oscilloscope (DPO) and its 7-GHz bandwidth, along with the CSA7404B communications signal analyzer, raise the performance bar for measuring and analyzing high-speed 1-Mbit/s to 3.125-Gbit/s serial data buses. The scope features a silicon-germanium (SiGe) trigger system with jitter as low as 1.0 ps rms and glitch detection as low as 110 ps.

"High-speed environments such as Fibre Channel, XAUI, InfiniBand, and PCI Express present engineers with significant analysis and interoperability challenges," says Colin Shepard, vice president of oscilloscope products. "Our customers are looking for test equipment that can handle the raw performance of the latest buses and, equally important, make complex, time-consuming testing fast and simple."

The oscilloscope's input rise time is 43 ps and delta-time measurement accuracy is within 1.5 ps rms. The unit's waveform-capture rate of more than 400,000/s, powered by Tektronix's DPX technology, is orders of magnitude faster than existing digital oscilloscopes.

The TDS7704B's robust waveform database-acquisition mode significantly reduces the time it takes to accrue the millions of cycles' worth of samples required by most compliance tests. A MultiView zoom feature makes it easy to expand localized waveform segments while maintaining an overall view of the larger record. The display is a full-color 1024- by 768-pixel 10.4-in. XGA unit.

The TDS7704B costs $59,000, and the CAS7404B goes for $57,500.
