A tuner is also a standalone home audio product, component, or device called an AM/FM tuner or a stereo tuner that is part of a hi-fi or stereo system, or a TV tuner for television broadcasts. The verb tuning in radio contexts means adjusting the receiver to detect the desired radio signal carrier frequency that a particular radio station uses.
Others offer continuous tuning over the whole shortwave frequency range, allowing the user to listen to amateur radio, marine, air, and utility stations as well as broadcasters. Tuners on analog receivers may include a bandspread control to allow accurate tuning of closely spaced frequencies.
In telecommunication, a measuring receiver or measurement receiver is a calibrated laboratory-grade radio receiver designed to measure the characteristics of radio signals. . The parameters of such receivers (tuning frequency, receiving bandwidth, gain) can be adjusted over a much more comprehensive range of values than other radio receive
One of the most basic forms of frequency meter is the vibrating reed meter or tuned reed meter. This consists of an electromagnet coil carrying the signal positioned near the end of a tuned metal reed or tuning fork-type arrangement. As the signal travels through the coil it creates a magnetic field with the sample frequency, which pushes and ...
The frequency range of the tuner is usually within the terrestrial broadcasting bands. Some FS meters can also receive satellite (TVRO and RRO) frequencies. Most modern FS meters have AF and VF circuits and can be used as standard receivers. Some FS meters are also equipped with printers to record received field strength.

A variable frequency oscillator (VFO) in electronics is an oscillator whose frequency can be tuned (i.e., varied) over some range. [1] It is a necessary component in any tunable radio transmitter and in receivers that work by the superheterodyne principle.
