Template Data Types
ABSOLUTE Templates
ABSOLUTE template data specify both wavelengths and levels as absolute values.
The waveform and template data change in conjunction with changes to the center
wavelength or display sweep width on the display scale.

When ZOOM CENTER WL is changed to 598.5 nm
(template also moves in synch with the waveform)
RELATIVE Templates
RELATIVE template data are specified as relative values with respect to the display
scale. These template data are fixed to the scale position even if the center wavelength
or display sweep width of the display scale is changed (not linked to the waveform).
When ZOOM CENTER WL = 600 nm
When ZOOM CENTER WL is changed to 598.5 nm
