Abstract
A spectrum analyzer (10) comprises a signal input or receiver (11) for receiving a signal, an A/D converter (12) configured to sample the received signal and generate a data stream of IQ-data, a digital processing circuit (13) for generating compressed data from the data stream of IQ-data, and a data interface (19) for outputting the compressed data from the spectrum analyzer (10).
Claims14
A radiofrequency spectrum analyzer, in particular a real-time radiofrequency spectrum analyzer, comprising:
- a radiofrequency signal input or receiver (11) for receiving a radiofrequency signal,
- an A/D converter (12) which is configured to sample the received radiofrequency signal and generate a data stream of IQ-data,
- a digital processing circuit (13) for generating compressed data from the data stream of IQ-data, wherein parts of the radiofrequency spectrum in which only background noise is present are replaced with a constant value or the average value of the amplitude or power spectrum and/or the IQ-data in the corresponding frequency range;
- and
- a data interface (19) for transferring the compressed data from the radiofrequency spectrum analyzer (10).
A method for outputting data from a radiofrequency spectrum analyzer (10), in particular for continuously transferring data from a real-time radiofrequency spectrum analyzer, comprising the steps of:
- A/D converting detected radiofrequency signals in order to generate a data stream of IQ-data, generating compressed data from the data stream of IQ-data, wherein parts of the radiofrequency spectrum in which only background noise is present are replaced with a constant value or the average value of the amplitude or power spectrum and/or the IQ-data in the corresponding frequency range, and
- outputting the compressed data from the radiofrequency spectrum analyzer (10) via a data interface (19) of the radiofrequency spectrum analyzer (10).
