Making Measurements
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:
• 1270–1650 maximum input wavelength range
• +10 dBm maximum total displayed input power
• Laser linewidths assumed to be less than 5 GHz
• If you change the elevation where you will be using your
Agilent 86120C, refer to “Calibrating Measurements” on page 2-37.
• Press the green Preset key to return the Agilent 86120C to its default
state.
CAUTION Do not exceed +18 dBm source power. The Agilent 86120C’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 2-36.
