Making Measurements

Defining Laser-Line Peaks

Peak excursion The peak excursion defines the rise and fall in amplitude that must take place in order for a laser line to be recognized. The rise and fall can be out of the noise, or in the case of two closely spaced signals, out of the filter skirts of the adjacent signal. The peak excursion’s default value is 15 dB. Any laser line that rises by 15 dB and then falls by 15 dB passes the rule. You can set the peak excursion value from 1 to 30 dB.

Examples of valid In the following figure, three laser lines are identified: responses 1, 3 and invalid signals and 4. Response 2 is not identified because it is below the peak

threshold. The portion of each signal that is within the peak excursion limits is shown in bold lines.

Because of the peak excursion rule, responses 4 and 5 are identified as one laser line—the minimum point between 4 and 5 does not drop to the peak excursion limit. This response has the highest power shown, which is peak 4.

Whenever the peak threshold limit or peak excursion value is changed, the new limits are applied to the current displayed measurements even if the instrument is in the Single measurement mode.
