Spectrum Monitoring Receiver from Digilogic Systems

1. Spectrum Monitoring Receiver Introduction: In today’s increasingly complex RF environments, efficient and precise spectrum monitoring is essential. Spectrum monitoring is a critical process in managing and optimizing the use of radio frequencies across various applications, including telecommunications, aerospace, and defence. By continuously observing the radio frequency spectrum, spectrum monitoring ensures compliance with regulatory standards, identifies unauthorized transmissions, and detects potential interference sources. Advanced Spectrum Monitoring Receiver systems utilize advanced technologies to analyse real-time frequency data, ensuring reliable performance and preventing service disruptions, safeguarding the spectrum, and enhancing communication infrastructure.

2. What is spectrum monitoring? Spectrum monitoring is performed by utilizing up-to-date highly integrated PXIe- based systems to demodulate and analyse digital and analog RF/IF signals. These systems which have been created in LabVIEW and utilizing Virtex- 5 FPGA technology, can acquire up to six signals from NI PXIe monitoring receivers. Some of these figures include the spectrum and small satellite mapping, the use of Waterfall/Spectrogram real-time probe, and RAID for post-analysis. Operations like ‘channelizing’ and ‘demodulation’ facilitate fine-tuning and selective filtering and decoding of the signals according to the characteristics set by the user. Why is spectrum monitoring important? Spectrum Monitoring Importance  Detects interprets, and successfully controls radio communication frequency signals. Promotes proper use of the available spectrum and identifies those who are using the frequency without authority. Reduced interference of the communications that are central to the functioning of the system. Uses such interfaces as panoramic spectrum displays and spectrograms in real-time. Helps in meeting the requirements of the laws, and aids in efficient spectrum management and coordination in case of an emergency. Maintains the cleanliness of the communication networks.

Signal Acquisition: Several RF/IF signals are received through the NI PXIe monitoring receivers. Digital Down conversion: In the receiver path the received signals are down converted to a lower frequency to allow easy digital processing. Channelization: The signals that are down converted are further partitioned into six independent paths for parallel processing. Signal Analysis: Regarding the signal acquired in each channel, signal processing is applied by utilizing numerous methods on LabVIEW. Visualization: Spectrum and waterfall are typical types of displays that give immediate information regarding signals. Data Storage: Some of the signals can be stored for analysis as well as for later playback. Page 3 of 7
