Measuring Laser Drift

maximum wavelength and maximum power may not have occurred simultaneously.

Display shows absolute minimum values since the drift measurement was started. This measurement gives the shortest wavelength and smallest power measured. The laser line of interest may have since drifted to a greater value. Note that the minimum wavelength and minimum power may not have occurred simultaneously.

Display shows the total drift from the reference since the drift measurement was started. Values represent the minimum wavelength and power drift values subtracted from the maximum drift values.

5In the List by WL and List by Power displays, use the and softkeys to view the reference values (wavelength and power values of each laser line before the test was started).

During the measurement, you can change the display mode to Peak WL,

List by WL, List by Power, or Avg WL. When List by WL or List by Power is selected, the signal list is sorted by reference values and not by the current, maximum, or minimum values.

To restart the drift measurements, press RESET. This resets the refer- ence values.
