The peak excursion and peak threshold settings define the laser modes included in the measurement. Because the default peak excursion value is 10 dB, measurement results normally include all laser modes within 10 dB of the peak response. Use the PK THLD softkey to change the number of laser modes used in the measurements. Refer to “Defining Laser- Line Peaks” on page 2- 15 for information on the peak threshold and peak excursion settings.

The peak excursion value (in dB) can also be used to determine which side modes are included in the measurements. To be accepted, each trace peak must rise, and then fall, by at least the peak excursion value about a given spectral component. Setting the peak- excursion value too high results in failure to include the smaller responses near the noise floor. Setting the value too low may cause unwanted responses, including noise spikes, to be identified. Use PK EXC to change the peak excursion value.
