Spectrum analyser: Displays frequency spectrum Sweep generator: Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester: Tests vacuum tubes (triode, tetrode etc.) Wattmeter: Measures power in a circuit Vectorscope: Displays the phase of the colors in color TV Video ...
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.
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 ...
In telecommunications, [1] particularly in radio frequency engineering, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB-millivolts per metre (dBmV/m).
A pressuremeter is a meter constructed to measure the “at-rest horizontal earth pressure”. The pressuremeter has two major components. [1] The first component is a read-out unit that remains above ground. The second component of the pressure meter is a probe that is inserted into the borehole (ground) to read the pressure.
