Using Variables and Traces

Using Amplitude Data

To select the amplitude units

￿Use the AUNITS command.

To convert measurement and parameter units

￿Use the AMPU command to convert measurement units to parameter units.

￿Use the MEASU command to convert parameter units to measurement units.

To return wavelength and position values

￿Use the POSU command to determines the trace point that corresponds to a wavelength value.

￿Use the WLU command determines the wavelength value of a given trace point.
