Frequency Response (Flatness)
Test Limits
20 Hz to 3.0 GHz
3.0 GHz to 7.5 GHz
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.
