PHYs are a crucial part of all SuperSpeed USB analyzers as they perform the critical role of decoding and deserializing the analog signals. These solutions typically fall into two categories: USB 3.0 compliant PIPE-based solutions, or non-compliant, generic deserializers.

Enhancing productivity is within reach with true real-time Protocol Analyzers. Coupling a blazing USB 3.0 downlink with the ability to begin debug sessions as soon as the "Start Capture" button is pressed enables a level of speed, scope, and precision not previously possible with any Protocol Analyzer.

CDPV analyzers can prolong debugging time, by requiring users to wait before seeing their application's data, or even causing prematurely terminated captures.

The real-time, interactive analysis offered by the Beagle™ USB 5000 v2 analyzer and the Data Center software allows developers to spend less time waiting for data, and more time on actual application development.

Signal probing techniques have become more complex as a result of the wide adoption of high-speed serial bus technologies, including USB, PCI Express, SAS, and SATA. With the technical challenges present from rapid increases in bus speeds, developers need to use active repeaters to probe high-speed signals. This article provides an overview of protocol analyzers and explores the probing design techniques used in today's high-speed protocol analysis solutions, including the Beagle™ USB 5000 SuperSpeed Protocol Analyzer.

This article will explore methods to quickly identify common problems that engineers may experience when developing a USB application. By using a USB protocol analyzer to provide visibility into the USB traffic, engineers can reduce development time and simplify the troubleshooting and debugging process.

At Cornell University, in the Autonomous Underwater Vehicle program, the Beagle I2C/SPI Protocol Analyzer was used extensively to help the students design and debug a passive acoustic array.

The Space and Systems Development Laboratory (SSDL) at Stanford University created the KatySat program to encourage K-12 students to pursue careers in science and technology. SSDL partnered with Total Phase to provide tools necessary for the project.

The complexity of the USB protocol increases the difficulty in identifying problems. USB protocol analyzers provide visibility into the raw USB traffic, allowing developers to quickly and efficiently identify problems.
