Multiple Waveform Comparisons
When comparing one or more waveforms, each against a common template
or against its own template, consider the following operating characteristics:
H You should set Horizontal Lock to None in the Zoom side menu (push
ZOOM and press (repeatedly) Horizontal Lock to None).
H With horizontal lock set as just described, the oscilloscope will reposition
each waveform horizontally to move the first sample in the waveform
record that is outside of template limits to center screen.
H If you are comparing each waveform to its own template, the position of
each waveform template will track that of its waveform.
H If you are comparing two or more waveforms to a common template,
that template will track the position of the failed waveform. If more than
one waveform fails during the same acquisition, the template will track
the position of the waveform in the highest numbered channel. For
example, CH 2 is higher than CH 1.
