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 measurement method, comprising acquiring, by a measurement apparatus, a plurality of at least three measurement segments, wherein each measurement segment is acquired at a corresponding measurement time, and wherein time information is gathered, wherein the time information allows to derive ratios of time differences between said measurement times; and playing back the plurality of at least three measurement segments, wherein each measurement segment is played back at a corresponding playback time, and wherein, using said time information, the playback times are chosen such that ratios of time differences between said playback times correspond to ratios of time differences between the corresponding measurement times.

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.

An electrical panel meter system may include a controller and a plurality of meter modules. Each meter module may be configured to monitor, read, and store at the meter module electrical data related to electrical power provided to a respective branch circuit of the electrical panel meter system. The controller may be configured to issue a read command simultaneously to each meter module and to store a timestamp indicative of the issuance of the read command. The controller may also be configured to issue a send command sequentially to each meter module to transmit its stored electrical data reading. The controller may further be configured to append the stored timestamp to each received electrical data reading to create a timestamped electrical data reading suitable for use in power quality analyzes. Methods of timestamping electrical data sampled in an electrical panel meter system are also provided, as are other aspects.
