Description of the Invention: [Technical Field] The present invention relates to a device for receiving satellite signals, and more particularly to a separate satellite receiving device and a detecting method thereof. [Prior Art] With the popularization of satellite TV, most of the system operators have multiple commercial satellites on the synchronous satellite, which can separately transmit satellite signals of different carriers to meet the needs of multi-frequency selection of installation users; The satellite receiving device composed of a multi-satellite signal input and a single output satellite down-converter (LNB) is installed at a reflection focus of a single dish antenna, and is received by a dish antenna. Each satellite signal sent by the system operator's commercial satellite, the reflective paraboloid of the dish antenna reflects the satellite signals to at least one receiving horn of the satellite receiving device. As an example of the "elliptical receiving horn with circular polarization" provided by U.S. Patent Nos. 7,229, 285 and 7,472,982, each satellite signal collected by the receiving horn can have different polarization types and transmission frequency bands. The polarization processing is used for the circuit processing of the downstream frequency reducer. Thus, the channel signal of each satellite signal can be outputted to the user terminal. 5青 Refer to the first figure as another conventional satellite input device 10 for multi-satellite signal input, and further add filtering processing corresponding to the satellite signal of the lower frequency band, and the packet 3 has a receiving horn 12, which is connected to the bottom of the receiving horn. The polarization processing member 14 is connected to the bottom plate 16 at the bottom of the polarization processing member 14, 201232920, and a frequency reducer (not shown) disposed between the polarization processing member 14 and the bottom plate 16. The satellite receiving device 10 receives a circularly polarized or elliptically polarized satellite signal of two different frequency bands by one of the waveguides 122 of the receiving horn 12, wherein the lower frequency satellite signal passes through the waveguide 122 and passes through the waveguide 122. The two filtering spaces 18 ′ between the polarization processing component 14 and the receiving horn 12 are respectively divided into horizontally polarized electromagnetic waves and vertically polarized electromagnetic waves, and the horizontally polarized electromagnetic waves and the vertically polarized electromagnetic waves are respectively located in the two filtering spaces 18 respectively. The square hole 142 at the end is transmitted to the downconverter; and the higher frequency satellite signal received by the receiving horn 12 is completely converted into a circularly polarized satellite signal by the waveguide 122, and then passed through the polarization processing device. When one of the circular holes 144 is formed, the two arcuate ribs 140 in the circular hole 144 (as shown in the second drawing A and B) are divided into a left-handed polarized electromagnetic wave and a right-handed polarized electromagnetic wave, and respectively fed out as horizontally polarized electromagnetic waves. Vertically polarized electromagnetic waves are transmitted to the downconverter. The downconverter processes the received four polarized electromagnetic waves by down-conversion, mixing, etc., and then outputs them from an external line (not shown). In the process of fabricating the satellite receiving device 10 described above, two important detection operations are performed, one of which is to detect the electromagnetic wave processed by the polarization processing component 14, and the other is to detect the frequency converter. Signal. However, before the installation of the downconverter, the satellite receiving device 10 needs to be assembled at the bottom of the square hole 142 of the polarization processing member 14 after the receiving horn 12 and the polarization processing member 14 are connected and assembled. A low frequency detecting device 19a as shown in FIG. AA and a high frequency detecting device 19b as shown in FIG. 3B are provided at the bottom of the circular hole 144 to perform the aforementioned detection of 201232920; After the imaginary, it can be loaded and lowered. The polarization detection result of 14 is the correct inspection, and the target group is the order of the Lantern. Therefore, it is not excluded to confirm the first item, and the mine/detection cannot detect the frequency reducer separately. Otherwise, the result of the inspection will show the financial error, and the test project will know that the bad defect of the satellite receiving device 1G occurs. Where == This detection method is very time consuming' so the satellite receiving device ι〇 still needs to be improved.

The signal outputted by the frequency reducer 60 is received through the output terminal group 58 by a circuit signal detecting device (not shown). And check 201232920 to measure 0. Thus, the detection result of the polarization processing detection portion can know whether the polarization processing member 40 has its function, and the detection result of the σ卩 is detected by the circuit. It can be known whether the down-converter 6 has the function it should have. Moreover, the two parts can be separately entered into two, and the separate satellite receiving device 2 does not need to connect other lines to the detecting devices, so the detecting method is very convenient. It is to be noted that the other embodiments of the present invention disclosed in the foregoing embodiments are not intended to cover the scope of the present invention. "or change" should also be the scope of patent application for this case
