Description
A signal source of known amplitude is connected to the spectrum
analyzer and the analyzer is adjusted for a reference level. The
amplitude of the signal peak is measured in 0.1 dB steps from -0.1 dB
to -1.9 dB, in 2 dB steps from -1.9 dB to -9.9 dB, and in 10 steps
from -10 dB to - 120 dB.
