USB, or Universal Serial Bus, is a connectivity standard that enables computer peripherals and consumer electronics to be connected to a computer without reconfiguring the system or opening the computer box to install interface cards. Teledyne LeCroy has pioneered the development of verifications systems for this new technology. Combined with the exerciser option and the CATC Trace expert software, the Voyager platform alleviates developers from tedious byte-level analysis and lets them focus on quick resolution of protocol layer problems. Each successive generation of the Teledyne LeCroy USB analyzer family has built upon the previous knowledge and expertise. This allows validation engineers to easily recreate problems reported in the field or test specific functionality using a simple trace file. Identifying the point where a specific bus event moves over a bridge is nearly impossible without the CrossSync synchronization solution.

Teledyne LeCroy has pioneered the development of verifications systems for this new technology. Now upgraded with SuperSpeed 3. Traffic summaries provide event metrics for USB 2. When enabled, the Advisor can monitor multiple sequential events with counters incorporated within each state.
Mass storage remains one of the most popular USB applications as consumers have embraced all types of digital media.
This scripting language is capable of opening and parsing any size trace file to allow users to automate routine analysis tasks such as performing timing calculations between link layer events or automating data compares for individual header fields.
By default, the ReadyLink emulation mode will automatically manage: Field upgradeable firmware allows the BusEngine lecriy evolve and support new features or future changes to the USB specification. Filtering logic can also include transaction layer packets with added criteria like direction or port number.
USB, or Universal Serial Bus, is a connectivity standard that k3i computer peripherals and consumer electronics to be connected to a computer without reconfiguring the system or opening the computer box to install interface cards. When enabled, the Intelliframe mode will intelligently wait for the appropriate response from the DUT before transmitting the next packet.

Identifying the point where a specific bus event moves over a bridge is nearly impossible without the CrossSync synchronization solution. With the Advisor T3, triggering can be specified at the lowest levels including bus states, ordered sets U0, SKP, etc…packet types, or lecryo fields End of Burst, Packets Pending, etc…. The first motherboards featuring USB 3.
The only company that offers a complete line of USB 3.
Unlike Pipe-PHY voyagfr analyzers that swallow 10 bit symbol errors, the Advisor T3 shows malformed packets, framing errors and invalid codes to allow unambiguous analysis of link problems. Peripherals add functionality to the host system or may be standalone embedded operation.
With its intelligent termination detect mode, the Advisor seamlessly captures in-band reset and lecrooy behaviors between devices. The original USB 1. Users can also create test scenarios by exporting any traffic stream from a previously recorded trace. This multifunction validation platform is available with an integrated exerciser capable of both 2.
For the USB IO subsystem in particular, the host manages the dynamic attach and detach of peripherals.

Each state change is shown graphically and is hyperlinked to the trace display. Identifying the point where a specific bus event moves over a bridge is nearly impossible without the CrossSync synchronization solution.
The Time Tune feature provides a real time slider for adjusting the offset between displays. This makes it easy to insert logic errors, perform corner-case, or stress testing. For SuperSpeed developers, the chapter 7 Link Layer tests have become an indispensable tool for verifying host, hub and devices coyager implement link training, link recovery and power management behaviors.
Designed to assist with low-level debugging, all ordered sets including training sequences and inter-packet symbols can be displayed in bit, 8-bit, scrambled, and unscrambled Hex format. It provided 12 Mbps data rate for higher-speed devices such as disk drives, and a lower 1. A library of predefined test scenarios including source code is provided allowing developers to adapt this substantial test suite to their own specific applications.
So the vast majority of USB devices typically fall into 2 categories:.
The software also provides chapter 9 framework and Elcroy coverage for devices to help validate upper layer protocol compliance. It also provides device descriptor information that drivers can use enable specific features on the device. The Voyager software provides many mechanisms to measure and report on USB 2. When using the CrossSync option, users can access the full complement of analysis capabilities available within each individual Teledyne LeCroy software.
