Software Suite Boosts Options on USB Protocol Analysers
Agilent Technologies has announced a new analysis software suite for the U4611A, U4611B and U4612A family of USB protocol analysers. The suite features the new MegaZoom technology, offering USB device designers quick and easy insight into their designs' behavior, and streamlining USB test and validation.
MegaMegaZoom delivers up to 18 GB of deep memory data capture without the sluggish response times and complex user interfaces inherent with traditional analyzers.
With patented indexing techniques performed in proprietary FPGA designs, MegaZoom can analyze the 5Gbps bi-directional data of USB 3.0 in real time.
Results are displayed in seconds, providing instant access to all events in the capture with a single click.
MegaZoom is not a special mode-it performs at full bandwidth in every capture, regardless of additional triggers and analysis performed by the analyser.
The software allows the analysers to monitor and capture bus activity and provide immediate access to the full detail of the entire data capture buffer-up to 18GBit. Real-time performance information is calculated, counted, logged and graphed in a single display. Performance data allows designers to quickly and easily identify the events that are causing throughput problems, endpoint data retry and communication errors.
In addition to providing a complete set of features for measuring packet performance, the new Link Training Status State Machine (LTSSM) views allow designers to see the real-time current state of the USB link while performance information is collected. This same LTSSM information is captured and stored with the data capture for full detailed analysis.
