a. When making a power measurement, the display shows the output
power measured at the analyzer’s RF IN 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.
