Scale Fidelity Test
Test
A signal source of known amplitude is connected to the spectrum
analyzer and the analyzer is adjusted for a reference. The signal
source is stepped down from -10 dB to -30 dB in 10 dB steps, and
the amplitude of the displayed signal is measured using the marker
function. This measured value is used to calculate the percent error
from the established reference level.
