Abstract:
1. An apparatus for testing stability of a data transfer rate of an electronic device, the apparatus comprising: a test interface for connecting the apparatus to the electronic device, the test interface being a USB interface; a data collector for receiving data represented by differential signals comprising data signals and clock signals transmitted from the electronic device via the test interface and capturing the data signals and the clock signals to generate test data compatible with the apparatus, the test data comprising USB packets; an analysis module coupled to the data collector for handling the USB packets of the test data and recognizing endpoints of the USB packets to generate analyzed data; an encoder constructed and arranged for receiving the analyzed data and encoding the analyzed data to generate output data; a display module; and a display controller couple to the encoder and the display module for controlling the display module to display a state of the data transfer rate based on the output data.
