Managing Predefined Parameters (Presets)
Managing Predefined Parameters (Presets)
A preset is a set of parameters that you can use to configure the source in a
single operation. Presets are especially useful when you often need to set
the source to specific parameters.
Note: In Dither Modulation or On/Off Modulation modes, the application will not
retain any modulation information. Saved parameters are only related to
wavelength and power (actual values or delta temperature/current).
Presets list contains default values (defined by EXFO and calibrated at the
wavelength specified at time of purchase) and user-defined values. Each
preset is saved under a specific name. Presets appear on a list in the main
window.
You can remove or rename any preset from the list, except the default
ones.
