Digital phosphor scope
improves on 2GHz devices
The latest addition to the Tektronix TDS7000 Series DPO family is the 2.5GHz TDS7254
The latest addition to the Tektronix TDS7000 Series DPO family is the 2.5GHz TDS7254, based on the same high-performance characteristics, graphical user interface and Open Windows platform as the 4GHz TDS7404 DPO introduced last year and the world's fastest real time oscilloscope. Using the same SiGe technology found in the TDS7404, the TDS7254 DPO is suitable for a variety of advanced test applications including signal integrity measurements and jitter and timing analysis.

Software has scope for ultrawideband testing
Package extends the debug and analysis capabilities of DPO/DSA70000 oscilloscopes to include real-time analysis of ultrawideband RF and electrical signals
"Semiconductor speeds in the newest electronics designs are driving the need for high-performance test equipment.
Our customers in the communications and computer industries are finding that the current 2GHz instruments on the market are simply not providing enough headroom to accurately measure signal integrity", said David Churchill, vice president, Instrumentation Business Unit, Tektronix.
"The TDS7254 fills that performance gap, and provides what is believed to be the most accurate representation of circuit behaviour available at an excellent value for customers who don't need the premium performance of the TDS7404 DPO".
As clock frequencies in the computer and communications industries continue to climb, signal integrity and timing margin issues have become crucial.
The TDS7254 leverages the TekConnect signal interconnect system to fully address signal integrity analysis, even when dealing with the 200ps edges typical of today's high speed components.

Waveform generator validates long Infiniband cable
Tektronix has has used its AWG7102 arbitrary waveform generator to validate the performance of the new Intel 100m Infiniband cable operating at speeds up to 20Gbit/s
An option available with this system includes the 4GHz (120ps risetime) P7240 active probe and the 3GHz (130ps risetime) P7330 differential probe.
The P7330 provides direct access to differential signals such as LVDS and similar technologies without requiring the user to dedicate two scope channels.
The 20Gsample/s real-time sample rate and delta-time measurement precision deliver superb jitter analysis results.
Measurements can be made on differential signals and between two separate input channels.
Comprehensive statistics and histograms of the timing parameters, and also trend plots, enhance its powerful analysis capabilities.
Pioneered by Tektronix, the first DPO was introduced in June 1998 as a new approach to signal acquisition.
The DPO architecture dedicates unique ASIC hardware to capture signal data at over 400,000 waveforms per second, giving design engineers an unmatched ability to view signals and circuit behaviour.
Based on an Open Windows platform, this innovative instrument offers unprecedented customisation and extensibility using Windows-compatible hardware and software, including third-party analysis tools.
The TDS7254 DPO provides engineers with advanced test capabilities for verification, debug and characterisation of sophisticated electronic designs.
Classic analogue-style controls, large touch-sensitive display and graphical menus provide intuitive control.
Standard interfaces allow expansion of the TDS7254 to include peripherals such as storage devices, a modem, or a wireless LAN connection.
Once networked, users can share files with team members worldwide, access print resources, reference design data via the Web, and exchange e-mail.
And, using the dual-monitor mode supported by Windows, designers can refer to and exchange this critical information while simultaneously making measurements on any of the TDS7000 Series.
