The frequency response test measures the signal analyzer's amplitude error as
a function of the tuned frequency. Measurements are made ranging from 50
MHz to the maximum frequency range of your analyzer. The signal source
amplitude is measured with a power meter to eliminate error due to source
flatness. The measured value is normalized to 50 MHz.
