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.
