2 Press the THRSHLD softkey.
3 Press PX EXC, and enter the peak excursion value. Use the
digit that requires editing. Use the
The peak excursion value can range from 1 to 30 dB. The default value is 15 dB.
4 Press RETURN.
5 Press 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 en-
sures 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 val-
ues to their default settings. It also turns wavelength range limiting on. Turning the
Agilent 86120B'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 100. 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.
