Protocol Analyzer

Overview:
The LE-650H2 is a USB protocol analyzer that supports high-capacity recording to a computer's HDD/SSD, detailed translation display at various levels, and VBUS power measurement. It automatically identifies and tracks USB 2.0/1.1 specifications at High/Full/Low speeds. USB testing can be initiated simply by pressing the space bar on the keyboard.
With simple operation that only requires connection to a computer's USB port, it offers an economical one-unit-per-person solution. It is ideal for the development and debugging of USB firmware and drivers, and can also be used for educational purposes related to USB specifications.

Features:
● Continuous recording of 10GB data to computer HDD/SSD
● Perform data search and detailed translation display at any time without stopping the test
● Real-time display of the bus power status of the test target
● Collect statistical information such as transmitted byte count and average transmission rate within a specified range
● Trigger and filter functions to improve testing efficiency
● Aluminum casing reduces noise impact and enables compact design.

*1: Records Bus Reset, Suspend, Disconnect under the following conditions.
Bus Reset When SEO state of D+/D- signals is detected for 2.5μsec or more but less than 139.8msec
Suspend When no communication time other than SEO state is detected for 3msec or more
Disconnect When SEO state of D+/D- signals is detected for 139.8msec or more
Note) When connecting/disconnecting USB cables, D+/D- signals may be unstable, possibly causing inconsistency with the actual bus state of the target device.
