a. When making a power measurement, the display shows the power
measured at the analyzer's input connector. This power is absolute
power, as opposed to a power ratio.
b. Note that when making a power measurement, the values
associated with the vertical axis are in units of dBm, which is the
power measured in reference to 1 mW.
• 0 dBm = 1 mW
• −10 dBm = 100 µW
• +10 dBm = 10 mW
Other units available for a power measurement include dBW,
dBµW, W, mW and µW.
