2. NetSpot - Wikipedia

   en.wikipedia.org/wiki/NetSpot

   NetSpot provides all professional wireless site survey features for Wi-Fi and maps coverage of a living area, office space, buildings, etc. [3] It provides visual data to help analyze radio signal leaks, discover noise sources, map channel use, optimize access point locations. Also, the application can perform Wi-Fi network planning: the data ...

3. Real-time analyzer - Wikipedia

   en.wikipedia.org/wiki/Real-time_analyzer

   A real-time analyzer (RTA) is a professional audio device that measures and displays the frequency spectrum of an audio signal; a spectrum analyzer that works in real time. An RTA can range from a small PDA -sized device to a rack-mounted hardware unit to software running on a laptop .

4. Spectrum analyzer - Wikipedia

   en.wikipedia.org/wiki/Spectrum_analyzer

   A spectrum analyzer is also used to determine, by direct observation, the bandwidth of a digital or analog signal. A spectrum analyzer interface is a device that connects to a wireless receiver or a personal computer to allow visual detection and analysis of electromagnetic signals over a defined band of frequencies.

5. Smaart - Wikipedia

   en.wikipedia.org/wiki/Smaart

   Although pink noise is a traditional choice for test signal, [3] Smaart is a source-independent analyzer, which means that it does not rely on a specific test signal to produce measurement data. Pink noise is still in common usage because its energy distribution allows for quick measurement acquisition, but music or another broadband test ...

6. Noise-figure meter - Wikipedia

   en.wikipedia.org/wiki/Noise-figure_meter

   A noise-figure meter could automate that procedure as follows: A gated broadband noise source (such as an avalanche diode) drives the device under test. A measurement is made with the noise source on; another measurement with the noise source off. From those measurements and the characteristics of the noise source, the noise figure can be ...

7. PicoScope (software) - Wikipedia

   en.wikipedia.org/wiki/PicoScope_(software)

   PicoScope for Microsoft Windows is the full-featured oscilloscope application, and was first released in 1992 by Pico Technology.PicoScope software enables real-time scope display with zooming and panning, and buffers captured waveforms on the PC to enable engineers to view previous measurements. [9]

8. Spectral density estimation - Wikipedia

   en.wikipedia.org/wiki/Spectral_density_estimation

   Multitaper is a periodogram-based method that uses multiple tapers, or windows, to form independent estimates of the spectral density to reduce variance of the spectral density estimate Singular spectrum analysis is a nonparametric method that uses a singular value decomposition of the covariance matrix to estimate the spectral density

9. Flicker noise - Wikipedia

   en.wikipedia.org/wiki/Flicker_noise

   The measurement of 1/f noise spectrum in voltage or current is done in the same way as the measurement of other types of noises. Sampling spectrum analyzers take a finite-time sample from the noise and calculate the Fourier transform by FFT algorithm. Then, after calculating the squared absolute value of the Fourier spectrum, they calculate its ...
