Using the Multi-Wavelength Meter
In this chapter, you’ll learn how to make a variety of fast, accurate measurements.
As you perform these measurements, keep in mind the following points:
• 700 nm to 1650 nm maximum input wavelength range
The range is normally limited from 1200 nm to 1650 nm. To use the full range, refer
to “Measuring lasers between 700 nm and 1200 nm” on page 44 .
• +10 dBm maximum total displayed input power
• Laser linewidths assumed to be less than 10 GHz
• If you change the elevation where you will be using your Agilent 86120B, refer to
“Calibrating Measurements” on page 63 .
• Press the green Preset key to return the Agilent 86120B to its default state.
C A U T I O N
Do not 18 dBm source power. The Agilent 86120B’s input circuitry
can be damaged when total input power exceeds 18 dBm. You can measure
power levels that are greater by adding attenuation and entering a power
offset as described in
“To measure total power exceeding 10 dBm” on page 62
