System and method for simultaneous display of waveforms generated from input signals received at a data acquisition device
First Claim
1. A method comprising:
- receiving a first input signal at a first input channel of a data acquisition (DAQ) device;
after receiving the first input signal at the first input channel, refreshing a display to visually present the first input signal at the first input channel as a first present-time waveform for the first input channel;
receiving, while the first input signal at the first input channel is visually presented as the first present-time waveform for the first input channel, a first user input at a user interface and responsively tagging the first input signal at the first input channel as a first historical waveform for the first input channel; and
after receiving the first input signal at the first input channel, receiving a second input signal at the first input channel and responsively refreshing the display to visually present, simultaneously, the second input signal at the first input channel as a second present-time waveform for the first input channel and the first input signal at the first input channel as the first historical waveform for the first input channel.

Abstract
A method and system for displaying waveforms generated from input signals received at a common input channel (CIC) of a data acquisition (DAQ) device. An input signal received at the CIC can be displayed as a present-time waveform, and while the input signal is displayed as a present-time waveform, the input signal can be tagged for displaying the input signal as a historical waveform for the CIC. After receiving another input signal at the CIC, a display can be refreshed to display, simultaneously, the historical waveform for the CIC and the other input signal as another present-time waveform for the CIC. The DAQ device can tag the displayed input signal in response to a user pushing a selector device on the DAQ device. The display can display other present-time waveforms with the historical waveform to allow a user to compare input signals received at the CIC.

12. 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
