System and method for simultaneous display of waveforms generated from input signals received at a data acquisition device

A system comprising:

• a first input channel that receives input signals, wherein the input signals received at the first input channel comprise a first input signal at the first input channel and a second input signal at the first input channel, wherein the first input signal at the first input channel is at the first input channel prior to the second input signal at the first input channel;
• a display that is operable to visually present each input signal at the first input channel as a respective present-time waveform for the first input channel, wherein, after receipt of the first input signal at the first input channel, the display is refreshed to visually present the first input signal at the first input channel as a first present-time waveform for the first input channel;
• a processor;
• a user interface that is operable to receive user inputs;
• and
• a data storage device containing computer-readable program instructions that are executable by the processor to tag input signals as historical waveforms,
• wherein, in response to the user interface receiving a first user input while the first input signal at the first input channel is visually presented as the first present-time waveform for the first input channel, the processor executes the computer-readable program instructions to tag the first input signal at the first input channel as a first historical waveform for the first input channel, and
• wherein, after receipt of the second input signal at the first input channel, the display is refreshed to visually present, simultaneously, the first input signal at the first input channel as the first historical waveform for the first input channel and the second input signal at the first input channel as a second present-time waveform for the first input channel.

A data acquisition device comprising:

• an input element including at least one input channel to receive input signals, wherein the at least one input channel includes a first input channel, and wherein the input signals include a first input signal received at the first input channel and a second input signal received after receipt of the first input signal;
• a display to visually present the first input signal as a first present-time waveform for the first input channel;
• a processor;
• a user interface to receive user inputs;
• and
• a data storage device storing computer-readable program instructions (CRPI),
• wherein the CRPI include program instructions executable by the processor to tag, in response to a user input received by the user interface while the display visually presents the first input signal as the first present-time waveform, the first input signal as a first historical waveform, and
• wherein the CRPI include program instructions executable by the processor to refresh the display to visually present, simultaneously, the first input signal as the first historical waveform and the second input signal as a second present-time waveform.

A display device comprising:

• a wireless transceiver to receive, from a wireless network, data representing input signals received by an input channel of a data acquisition device, wherein the received data includes data representing a first input signal received at the input channel and data representing a second input signal received by the data acquisition device after receipt of the first input signal;
• a display to visually present the data representing the first input signal as a first present-time waveform for the input channel;
• a processor;
• a user interface to receive user inputs;
• and
• a data storage device storing computer-readable program instructions (CRPI),
• wherein the CRPI include program instructions executable by the processor to tag, in response to a user input received by the user interface while the display visually presents the data representing the first input signal as the first present-time waveform, the first input signal as a first historical waveform, and
• wherein the CRPI include program instructions executable by the processor to refresh the display to visually present, simultaneously, the data representing the first input signal as the first historical waveform and the data representing the second input signal as a second present-time waveform.
