Tektronix Inc. now markets a broad set of oscilloscope firmware and software upgrades designed to simplify and shorten serial bus debug cycles. It also announces enhanced support for a number of important serial bus standards including PCI Express, CAN/LIN, FlexRay, MIL-STD-1553B and MOST (Media Oriented System Transport).

The diversity and complexity of serial buses give engineers less time than ever to focus on solving signal integrity issues. The new Tektronix products were designed to simplify serial bus debugging and verification, while building a deep level of intelligence about serial buses into its Performance Oscilloscope Series.

By using a single instrumentthe oscilloscopeTektronix enables customers to quickly identify timing or protocol-based errors, thereby saving engineering time and lowering equipment costs.

The company's new oscilloscope features Visual Trigger, a flexible trigger system that enables the capture of unique events. Visual Trigger allows engineers to create highly customizable shapes using their mouse or touchscreen that closely match the desired waveform of interest.

This highly intuitive capability could change the way engineers interact with the trigger system on an oscilloscope. Also, with a new Mark All Trigger Events capability, the Tektronix Performance Trigger system ensures capture and search of all potential complex behaviors in a given acquisition of interest.

Tektronix also provides the custom analysis interface for use with MATLAB, giving oscilloscope users unique plotting and filter capabilities for greater depth of analysis.

This latest update further enables Tektronix oscilloscope users to better identify crosstalk in their designs without having to resort to a bit error rate tester. The DPOJET jitter and eye diagram analysis tool now incorporates an algorithm for correctly identifying crosstalk induced jitter as bounded uncorrelated jitter (BUJ).

This means real-time oscilloscopes can be used for measuring total jitter and can separate crosstalk or ISI from other jitter sources. Also, libraries can be created using Microsoft Visual Studio to customize measurements in DPOJET.

The new BUJ-aware version of DPOJET accurately represents crosstalk, and creates more confidence in the accuracy of the TJ@BER (Total Jitter at Bit Error Ratio) numbers coming from the oscilloscope.

DPOJET has also been enhanced with the ability to add customized measurements. It now includes support for logic signals acquired using the mixed signal functionality in Tektronix MSO5000 and MSO70000 Series oscilloscopes. This logic channel capability allows up to 16 address and command bus signals to be integrated into the DPOJET debug environment.

By also providing automated test suites, Tektronix eliminates the need for engineers to be experts in every standard. This latest release speeds up serial bus verification for design engineers in two important industries: automotive and high-end computing.

In support of the growing use of electronics in automotive products, Tektronix is rolling out robust CAN/LIN support and new capabilities for analyzing FlexRay and MOST buses. These buses are widely used across the automotive industry and in other products such as lightweight aircraft and heavy equipment.

Tektronix is now offering PCI Express PHY Layer Decode support for all variations of this popular bus standard. This enhances an already strong level of 8b/10b decode capability while speeding up PCIe design verification and troubleshooting for engineers.

The new version of DPOJET is available now. Firmware updates for DPO/MSO5000 Series, DPO7000C and DPO/DSA/MSO70000C/D Series oscilloscopes are available free of charge on the Tektronix website.
