Points A solid waveform indicates a channel live waveform display The waveform remains solid when the acquisition 1s stopped if no controls are changed that make the display accuracy uncertain Changing the vertical and horizontal controls is allowed on stopped acquisitions For TDS1000B models monochrome display reference waveforms or waveforms with persistence appear dimmed For TDS2000B models color display reference waveforms appear white and waveforms with persistence applied appear in the same color as the Main waveform but with less intensity A broken line indicates the waveform display no longer matches the controls This happens when you stop the acquisition and change a control setting that the oscilloscope is not able to apply to the displayed waveform For example changing the trigger controls on a stopped acquisition causes a broken line waveform Persistence The oscilloscope displays persistence waveform data with less intensity than live waveform data With Persistence set to Infinite record points accumulate until a control is changed Option Comments Off Removes default or old waveforms whenever new waveforms display Time limit Displays new waveforms at normal intensity and old waveforms at a lower intensity erases old waveforms when they reach the time limit Infinite Older waveforms become less bright but always remain visible use Infinite persistence to look for infrequent eve
