Description
Technical field
The present invention relates to device, particularly about a kind of separate type satellite receiver and detection method thereof in order to receiving satellite signal.
Background technology
Along with the universalness of satellite television, big multisystem dealer all has many commercial satellite on synchronous satellite orbit, and the satellite-signal that can send out different carrier respectively satisfies the demand that user's multifrequency is selected of installing; Generally speaking; The user can be many satellite frequency demultiplier (the LowNoise Block-downconvertor of satellite-signals input and single output; LNB) satellite receiver that is constituted; Be set up in the reflect focalization place of single disc-shaped antenna, with each satellite-signal that disc-shaped antenna receiving system dealer's commercial satellite is seen off, the reflection paraboloid of disc-shaped antenna reflexes to each satellite-signal at least one reception bugle (feed horn) of satellite receiver again.Announcing " have the ellipse that circular polarization handles and receive bugle " of being provided for No. 7239285 and No. 7642982 with United States Patent (USP) is example; Each satellite-signal by receiving the bugle collection can have different polarization kind and transmission band; Handling for the frequency demultiplier of back grade and make processing of circuit through receiving the corresponding polarization of bugle, so is that the entrained channel signals of exportable each satellite-signal is to client.
See also Fig. 1; Satellite receiver 10 for another existing many satellite-signal inputs; More add corresponding Filtering Processing than the low-frequency range satellite-signal; Include one and receive the polarization that bugle 12, is connected in these receptions bugle 12 bottoms and handle the base plate 16 that part 14, is connected in these polarization processing part 14 bottoms, and the frequency demultiplier (not shown) be located between this polarization processing part 14 and this base plate 16.This satellite receiver 10 receives the circular polarization or the elliptical polarization satellite-signal of two different frequency ranges with its wherein waveguide pipe 122 that receives bugle 12; Wherein can be after this waveguide pipe 122 than the satellite-signal of low frequency; Through handle two filtering spaces 18 between part 14 and this reception bugle 12 in this polarization; Be divided into horizontally polarized electromagnetic wave and vertically polarized electromagnetic wave respectively, these horizontally polarized electromagnetic waves and vertically polarized electromagnetic wave can transfer to this frequency demultiplier from being positioned at these two filtering space, 18 terminal square holes 142 respectively again; The satellite-signal of the higher-frequency that this reception bugle 12 is received then can convert the circular polarization satellite-signal into through waveguide pipe 122 fully; Afterwards when handling a circular hole 144 of part 14 through this polarization; Two arc ribs 146 (shown in Fig. 2 A, Fig. 2 B) by in this circular hole 144 are divided into Left-hand polarized electromagnetic wave and right-hand polarized electromagnetic wave, feed out respectively to horizontally polarized electromagnetic wave and vertically polarized electromagnetic wave again and transfer to this frequency demultiplier.This frequency demultiplier can be made frequency reducing, smear or the like with these received four kinds of polarized electromagnetic waves and handle, and is exported by the external circuit (not shown) again.
In the process of making aforementioned this satellite receiver 10, need carry out two important testings, wherein one is 14 electromagnetic waves of handling out of this polarization processing part of detection, and another is then for detecting the signal that this frequency demultiplier is handled out.Yet; This satellite receiver 10 is before the installing frequency demultiplier; Need be after this reception bugle 12 and polarization processing part 14 interconnect the assembling completion; Just can install the low frequency checkout gear 19a shown in Fig. 3 A respectively in square hole 142 bottoms of this polarization processing part 14, and in the high-frequency detection device 19b of this circular hole 144 bottoms installing shown in Fig. 3 B, to carry out aforementioned first detection; Confirm polarization handle the polarization testing result of part 14 be correctly after, just can load onto frequency demultiplier, and the handled signal of frequency demultiplier is transferred to a circuit signal checkout gear (not shown).So before not getting rid of the error of confirming first detection; Can't detect this frequency demultiplier separately; Otherwise in case the result of final this circuit signal checkout gear has error slightly; Testing engineering can't learn then where the bad defective of this satellite receiver 10 betides, and causes so detection mode very consuming time, so this satellite receiver 10 still remains to be improved.
