Abstract
An apparatus for measuring spectral components of a signal is described. The apparatus comprises a measurement acquisition unit configured to receive an input signal and to provide a measurement trace. The apparatus also comprises a model module configured to model one or more of a phase noise from the apparatus, a broadband noise from the apparatus, and a third order intermodulation (TOI) product from the apparatus. The apparatus also comprises a display configured to show one or more of the phase noise from the apparatus, the broadband noise from the apparatus, and the TOI product from the apparatus.
Claims15
An apparatus for measuring spectral components of a signal, the apparatus comprising:
- a measurement acquisition unit that receives an input signal and to provide a measurement trace;
- a model module that models one or more of a phase noise from the apparatus and a broadband noise from the apparatus, and that models a third order intermodulation (TOI) product from the apparatus;
- and
- a display that shows one or more of the phase noise from the apparatus, the broadband noise from the apparatus, and the TOI product from the apparatus.
A method of displaying a measurement of a spectrum of a signal, the method comprising:
- measuring one or more of a phase noise and a broadband noise;
- measuring a third order intermodulation (TOI) product of a signal under test (SUT);
- modeling one or more of a phase noise, a broadband noise from a spectrum analyzer;
- modeling a TOI product from the spectrum analyzer;
- and displaying the selected one or more of the phase noise, the broadband noise and the TOI products of both the SUT and the spectrum analyzer.
An apparatus for measuring spectral components of a signal, the apparatus comprising:
- a measurement acquisition unit that receives an input signal and to provide a measurement trace;
- a model module that models one or more of a phase noise from the apparatus, a broadband noise from the apparatus, and that models a third order intermodulation (TOI) product from the apparatus, wherein the model module comprises:
- a controller and a computational unit that models the phase noise, the broadband noise and the TOI products over a frequency range and a power level range of the signal;
- and
- a display that shows one or more of the phase noise from the apparatus, the broadband noise from the apparatus, and that shows the TOI product from the apparatus.
