REF Function

Reference Waveforms are saved waveforms to be selected for display. The reference

function will be available after saving the selected waveform to non-volatile memory.

During the actual measurement process, you can use DS1000B series digital

oscilloscope to observe the waveforms of correlative components. It will help you to

determine the cause of malfunction when you compare the measured waveform with

the reference waveform. The method is particularly useful under the circumstance of

having reference waveforms.

Press REF button to display the Reference waveform menu.
