Description
A signal of the same known amplitude is applied to the spectrum analyzer at several different
frequencies. At each frequency, the DAC controlling the flatness compensation amplifiers
is adjusted to place the peak of the displayed signal at the same place on the screen. The
preselector is centered at each frequency before setting the DAC value. The DAC values are
stored in EEROM.
