  2. SWR meter - Wikipedia

    en.wikipedia.org/wiki/SWR_meter

    An SWR meter does not measure the actual impedance of a load (the resistance and reactance), but only the mismatch ratio. To measure the actual impedance requires an antenna analyzer or other similar RF measuring device. For accurate readings, the SWR meter itself must also match the line's impedance (typically 50 or 75 Ohms).

  3. Antenna analyzer - Wikipedia

    en.wikipedia.org/wiki/Antenna_analyzer

    An antenna analyzer measuring SWR and complex impedance of a dummy load. MFJ-269, MFJ Enterprises Inc. An antenna analyzer or in British aerial analyser (also known as a noise bridge, RX bridge, SWR analyzer, or RF analyzer) is a device used for measuring the input impedance of antenna systems in radio electronics applications.

  4. Standing wave ratio - Wikipedia

    en.wikipedia.org/wiki/Standing_wave_ratio

    Checking the SWR is a standard procedure in a radio station. Although the same information could be obtained by measuring the load's impedance with an impedance analyzer (or "impedance bridge"), the SWR meter is simpler and more robust for this purpose. By measuring the magnitude of the impedance mismatch at the transmitter output it reveals ...

  5. Antenna feed - Wikipedia

    en.wikipedia.org/wiki/Antenna_feed

    The antenna feed system or antenna feed is the cable or conductor, and other associated equipment, which connects the transmitter or receiver with the antenna and makes the two devices compatible. [ 1 ] [ 2 ] In a radio transmitter, the transmitter generates an alternating current of radio frequency , and the feed system feeds the current to ...

  6. List of amateur radio transceivers - Wikipedia

    en.wikipedia.org/wiki/List_of_amateur_radio...

    As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...

  7. Antenna tuner - Wikipedia

    en.wikipedia.org/wiki/Antenna_tuner

    Cross-needle SWR meter on antenna tuner. It is a common misconception that a high standing wave ratio (SWR) per se causes loss. [3] A well-adjusted ATU feeding an antenna through a low-loss line may have only a small percentage of additional loss compared with an intrinsically matched antenna, even with a high SWR (4:1, for example). [21]

  8. NTi Audio - Wikipedia

    en.wikipedia.org/wiki/NTi_Audio

    NTi Audio AG is a manufacturer of test and measurement instruments for acoustics, audio and vibration applications. With headquarters in Schaan, Liechtenstein, the company specializes in end-of-line audio testing for manufacturing quality control purposes, [1] provides instruments for testing public address systems in safety-critical environments [2] and also produces handheld Audio Analyzers ...

  9. Acoustical measurements and instrumentation - Wikipedia

    en.wikipedia.org/wiki/Acoustical_measurements...

    Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO. The work might also involve design fine-tuning to meet market ...
