<p>A method and system for displaying waveforms generated from input signals received at a common input channel (CIC) of a data acquisition (DAQ) device (104). 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 (1000) 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 (1010) 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.</p> |
