1. USB ESD device is added:The original does not have a USB ESD device, but this analyzer adds a 0522P ESD device. 2. FPGA with a speed grade of -4 greatly saves costs:The original version uses a FPGA with a speed grade of -5, which is too expensive. Under normal ambient conditions of use at room temperature, it is perfectly fine to use a FPGA with a speed grade of -4. 3. USB female connector for Foxconn:As a more frequently used interface, the USB female connector for Foxconn is used. 4. Optimize backside wiring:The original version is a double-sided PCB board. This version is changed to a single-sided PCB for easy production. 68013A may be replaced with CBM9002 due to different batches. Please make sure that you don't mind before purchasing. 5. A very low cost shell:The main body is aluminum, and the front and rear panels use FR4 PCB material. The host computer uses packet analyzer for Wireshark, which can only be used for win10/win11 x64. This is an open-source high-speed USB protocol analyzer. On the premise of reducing costs, its performance is as stable as the your one. Note: Please contact customer service about download or installation information before placing order. Colour:Black Material:Aluminum Alloy Package Contents: 1 x USB Protocol Analyzer(Due to different product batches, the appearance , which does not affect the use) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
