ABSTRACT:
A signal level measuring apparatus measures a level of a satellite signal from a geostationary satellite as received by a receiving antenna and provides an output to determine whether the antenna is correctly directed to the satellite. The apparatus is disposed between a converter associated with the antenna for converting the satellite signal into an IF signal and a tuner for demodulating the IF signal. The apparatus distributes and divides the IF signal from an input terminal of the apparatus into two output signals. One of the output signals is coupled to an output terminal of the apparatus, which, in turn, is coupled to the tuner. The other output signal is applied to level detector. An output from the level detector is compared with a reference signal. Depending on the comparison output, the state of light emission of a light-emitting device varies.
