Fourier transform
See FFT.
frequency accuracy
The uncertainty with which the frequency of a signal or spectraI component is indicated, either in an absolute sense or relative to some other signal or spectral component. Absolute and relative frequency accuracies are specified independently.
frequency range
The range over of frequencies which the analyzer performance is specified. The maximum frequency range of many microwave analyzers can be extended with the application of external mixers.
frequency resolution
The ability of an analyzer to separate closely spaced spectral components and display them individually. Resolution of equal amplitude components is determined by resolution bandwidth. Resolution of unequal amplitude signals is determined by resolution bandwidth and bandwidth selectivity.
frequency response
The
frequency span
The magnitude of the displayed frequency component. Span is represented by the horizontal axis of the display. Generally, frequency span is given as the total span across the full display. Some analyzers represent frequency span (scan width) as a
frequency stability
The stability of a frequency component to remain unchanged in frequency or amplitude over short- and
