Glossary
Span Per Division (Span/Div)
Frequency difference represented by each major horizontal division of the graticule.
Spectrogram
Frequency vs. time vs. amplitude display where the frequency is represented on the x-axis and time on the
y-axis. The power level is indicated by variations in color.
Spectrum
The frequency domain representation of a signal showing the power distribution of its spectral component
versus frequency.
Spectrum Analysis
The technique or process of determining the frequency content of an RF signal.
Spectrum Analyzer
A device for determining the frequency components of a signal.
Spectrum Time
Analysis Time for spectrum analysis views. Spectrum time can be the same as Analysis Time, but it
can be different.
Spur
A spur is a signal peak that exceeds a user-definable threshold (See Spurious > Settings > Ranges) and
excursion setting. A spur that also exceeds a limit (either Absolute or Relative) specified on the Settings
> Limits tab is considered a violation.
