  • Time-Dimension Models of Spectrum Usage for the Analysis, Design, and Simulation of Cognitive Radio Networks
    Thus, while USRP measurements are useful to accurately describe the true channel occupancy pattern at short timescales, spectrum analyzer measurements are useful to model the occupancy pattern perceived by DSA/CR users at longer timescales. Both measurement setups were employed to monitor spec- trum bands allocated to amateur systems (144–146 MHz); paging systems (157–174 MHz); Private/Public Access Mo- bile Radio (PMR/PAMR) systems such as TETRA UL (410–420 MHz) and TETRA DL (420–430 MHz); cellu- lar mobile communication …
  • Secrets of RF Circuit Design , Third Edition > Interpreting radio receiver specifications
    I’ve seen situations in amateur radio operations where the apparent third-order performance of a receiver improved dramatically when a lower gain antenna was used. The late J. H. Thorne (K4NFU) demonstrated the effect to me on a VHF band using a spectrum analyzer /receiver.
  • Radio frequenc surve of the 21-cm wavelength (1.4 GHz) allocation for passive microwave observing
    The spectrum analyzer was the primary detector and the communications receiver was used to listen to the received signals. The survey team included an experienced amateur radio operator who could hypothesize a signal’s type by listening to FM and/or AM demodulated audio.
  • Inexpensive method of demonstrating microwave fiber optics
    These frequencies are assigned for "radiolocation" and amateur radio is a secondary user in these bands.2 In order to ensure a "non-interference" situation, a spectrum analyzer was hooked up to the antennas at the desired frequency.
  • Use of a DRM modulation to study the ionosphere
    The reception of a numerical broadcasting (Digital Radio Mondiale) link associated to decode software (Dream) and a spectrum analyzer (SpectrumLab) constitutes an opportunistic technology to investigate the ionosphere. The novelty lies in the use of amateur type devices (laboratory receiver, sound card, open source software …
  • CR4 - Thread: DC Motor Causing Serious Interference?
    Look at the noise with a o'scope or preferably a spectrum analyzer to find the frequencies you are dealing with. Consult a book such as the Amateur Radio Handbook to build the proper filter to put inline with the motor.
  • Principles of Waveform Diversity and Design
    Various government and private agencies (the NTIA, the NRL Radar Division, and the Amateur Radio Relay League (ARRL)) have conducted investigations to determine the severity of interference that BPL might cause existing HF users. The test configuration consisted of a 150 ft energized BPL at a distance of 21 ft from a receiving system ( spectrum analyzer and loop antenna).
