2. Radio-frequency sweep - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_sweep

   A spectrum analyzer is a standard instrument used for RF sweep. It includes an electronically tunable receiver and a display. The display presents measured power (y axis) vs frequency (x axis). The power spectrum display is a two-dimensional display of measured power vs. frequency. The power may be either in linear units, or logarithmic units ...

3. 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.

4. Two-tone testing - Wikipedia

   en.wikipedia.org/wiki/Two-tone_testing

   A spectrum analyser – typically used as the measuring instrument in two-tone testing. Two-tone testing is a means of testing electronic components and systems, particularly radio systems, for intermodulation distortion. It consists of simultaneously injecting two sinusoidal signals of different frequencies (tones) into the component or system.

5. Radio spectrum - Wikipedia

   en.wikipedia.org/wiki/Radio_spectrum

   A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.

6. Low Frequency Analyzer and Recorder - Wikipedia

   en.wikipedia.org/wiki/Low_Frequency_Analyzer_and...

   A working model of the Low Frequency Analyzer and Recorder was delivered in May 1951 which operated with real time analysis of a frequency band of 1 to 1/2 Hz. Along with the working model was a proposal for hydrophones, cables, processing systems and beamforming so that a hydrophone array could present multiple azimuthal beams to be displayed. [7]

7. Signal analyzer - Wikipedia

   en.wikipedia.org/wiki/Signal_analyzer

   A signal analyzer is an instrument that measures the magnitude and phase of the input signal at a single frequency within the IF bandwidth of the instrument. It employs digital techniques to extract useful information that is carried by an electrical signal. [1] In common usage the term is related to both spectrum analyzers and vector signal ...
