A system and method are provided for displaying input signals from a DUT on a display screen. The method includes sending a data stream of digitized data received from the DUT to an FPGA for serial decoding; receiving decoded symbols from the FPGA; identifying valid symbols among the decoded symbols indicating transitions between the decoded symbols; storing the valid symbols with corresponding time-tags as valid packets in memory, and discarding ones of the decoded symbols occurring between the valid symbols; and plotting on the display screen the valid packets occurring between beginning and ending valid packets of the stored valid packets. The beginning valid packet has a corresponding time-tag occurring immediately before a first point time-tag associated with a left edge of the display screen, and the ending valid packet has a corresponding time-tag occurring at or immediately before a last point time-tag associated with a right edge of the display screen.

A network oscilloscope, including a network interface configured to receive a stream of network data, one or more processors, and a display. The one or more processors generate a timestamp for each data packet parsed from the stream of network data, extract a portion of information from each of the data packets received from the stream of network data, the portion of information being less than an entirety of information in each data packet, and generate a data record indicating extracted information and a timestamp for each data packet parsed from the stream of network data. The display configured to display at least a portion of the data record.
