Analyzing Results from the Results Graph
To zoom in on results or zoom out:
1. On the Results Graph tab, click the magnifying glass button.
2. Enter the desired range by putting a lower and upper limit value in the
fields of your choice. The wavelength, dispersion and RGD will be
magnified accordingly.
Note: You can only use the zoom function on extrapolated values that are within
the 1200 to 1700 nm wavelength acquisition range. Extrapolated values are
representative of the selected fit and might not represent the true behavior
of the fiber.

In the first level, you can enter the wavelength values you want to
see extrapolated in the Lower Limit and Upper Limit boxes.
³
You can also click More Details to access to additional parameters
for the zoom function. Enter the Dispersion or RGD value you
