Overview
Le Lineeye LE-650H2 est un analyseur USB basé sur le matériel, qui peut enregistrer une grande quantité de données sur le disque dur/SSD du PC, afficher la traduction à chaque décodage de classe et mesurer la consommation d'énergie VBUS. L'analyseur détecte automatiquement la vitesse élevée/pleine/faible de l'USB 2.0/1.1 et démarre la mesure en appuyant simplement sur la barre d'espace du PC. L'appareil à faible coût et facile à utiliser en le connectant au port USB du PC est utile pour développer/déboguer le micrologiciel/pilote et étudier la norme USB.
While recording 480Mbps high-speed transfer data of USB 2.0 to the hard disk of the PC via a large capacity memory of LE-620HS, displays the contents of that data on the screen of the PC in detail at real time. It can identify PING and the split transaction at high speed.
Easy operation USB analyzer with auto tracking of the USB Speed
Without affecting the communication carrying data between the analyzer and target device, the LE-650H2 series USB analyzer internally records large amounts of data and simultaneously transfer it to a connected PC via USB. The analyzer automatically detects the speed of the target devices (480/12/1.5 Mbps), so a speed setting is unnecessary. If the device is connected through a hub of differing speed, measurement can be started by simply pressing the space bar of the PC.
Smaller and Lighter
LE-650H2 has almost the same functions as the conventional model of the PC connectable USB analyzer LE-620HS has, but it is smaller and lighter by employing an aluminum case and 8-layer PCB.
Continuous Recording up to 10GB on HDD or SSD
The data measured by the USB analyzer is continuously transferred to the PC and recorded as log files with a maximum of 2GB (Can be specify every 1MB) on the HDD or SSD of the PC. Furthermore, it is possible to form a ring buffer to record maximum of 5 log files continuously by using repetitive recording mode. The measurement log data can be displayed and scrolled during measurement, which is effective for an extended analysis of rare communications failures.
Clearly Detailed Monitor Display
USB packets are clearly displayed by transaction. The device can identify PING and the split transaction at high-speed. Standard descriptors/device requests, descriptors of Communication/Printer class, and peculiar device requests of HUB/HID/Audio/Communication/Mass storage class are translated and displayed in detail, therefore the difficult-to-understand USB protocols can be intuitively understood.
Powerful Sequential Trigger
Trigger condition by a certain transmission data or an external signal condition Up to 16 actions can be set which will be executed when the trigger condition is established.
With these triggers you can control logging by synchronizing with external signal or cooperate with another measurement equipment by switching the external trigger signal to ON when a specify data is detected. It will help your analysis.
Perfect Offline Analysis Features
Data can be easily found among the huge volume of recorded data by using the filter function. It incorporates a advanced search function, such as searching for a standard request, class-divided request and class command.
Development efficiency is boosted to a higher level by using color-coded customization features for packet types and mark/jump features.
Detailed translation is possible by specifying the class for the data without emulation information.
