Measuring Absolute Power
Measuring Absolute Power
Press dBm/Watt to display the absolute power of the signal received at the
detector port. dBm/Watt is also used to toggle between dBm and watts
measurement units. When using watts measurement units, the Optical
Power Meter will automatically use pW, nW, μW, or mW, according to the
power of the signal. Press
λ to toggle between the wavelengths in the
shortlist (to edit the shortlist of wavelengths, see Customizing the Shortlist
of Wavelengths on page 33).
Note: “– – – – – – – –” indicates a reading below range. “++++++++” indicates
a reading above range.
