Making Measurements

Defining Laser-Line Peaks

3Press PX EXC, and enter the peak excursion value. Use the softkey

to select the digit that requires editing. Use the and softkeys to change the value.

The peak excursion value can range from 1 to 30 dB. The default value is 15 dB.

4Press RETURN.

5Press PK THLD and then enter the peak threshold value.

The peak threshold value can range from 0 to 40 dB. Setting this value to 0 dB ensures that only the peak wavelength is identified. The default value is 10 dB.

Pressing the green PRESET key changes the peak excursion and peak threshold values to their default settings. It also turns wavelength range limiting on. Turning the Agilent 86120C’s power off and then on does not change these settings.

If too many lines are identified

If the following message is displayed, too many laser lines have been identified:

E15 MAX NUMBER OF SIGNALS FOUND

The maximum number of laser lines that the instrument can measure is 200. If this message appears, decrease the peak threshold value, increase the peak excursion value, or decrease the wavelength range of operation with the WL LIM ....START WL and STOP WL functions.
