Test Description

The frequency response test measures the spectrum 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.
