USB Interface has been widely used in PC, Mobile Device, Tablet PC and other electronic products. In order to provide more perfect measurement, Zeroplus Technology, a leading manufacturer of Logic Analyzer, recently issues the Protocol Analyzer USB 2.0 Module, with which users can analyze the USB Interface signal. 　　Protocol Analyzer USB 2.0 Module of Zeroplus Technology can be used to analyze the USB 2.0 transmission control signal, and decode the packets of SYNC, SOF, FRAME, ADDRESS, ENDPOINT, DATA, CRC5/CRC16, EOP, SETUP, IN, OUT, PING, SPLIT, PRE, DATA0, DATA1, DATA2, MDATA, ACK, NACK, STALL, NYET, HUBADDRESS, SC, PORT, S, E and ET in the USB signal. The packet of signal can be displayed in graphical mode, so the time to decode and calculate by hand can be saved in this way. 　　With three decoding modes, this Module can decode USB1.0(low speed), USB1.1(full speed) and USB 2.0(high speed). Besides, it can display the second order packet data or filter the packet format from the captured signal, so as to speed up analyzing. With elegant appearance, simple operation and good design, Zeroplus Logic Analyzer can recode and display the received/transmitted data from the Protocol Analyzer. If there is any error, the Bug can be found quickly from the recoded data. It is a good helper for engineers. For more information, please call 886-2-6620-2225 or login www.zeroplus.com.tw.
