Sikhungo saseShanghai se-physics lesetjentisiwe (siap), sikolo sesayensi saseShayina (cas) kanye ne-xst bahlanganyela tandla kute bakhe umukeli we-shortwave losebenta kahle kakhulu
Kuphakela imikhicito
Ema-Receiver E-Shortwave Lasebenta Kakhulu
Bamukeli bemagagasi lamafishane kakhulu

I. Imvelaphi Nesingeniso
Sikhungo Se-Shanghai Sesayensi Lesetjentisiwe (i-SIAP) seSikolwa Setesayensi SaseShayina (i-CAS) sikhungo selucwaningo lesibalulekile emkhakheni wesayensi yenuzi netebucwepheshe, lesine ‘Lilabhorethri Lebalulekile Le-Microinterface Physics Nekutfola Ye-Akhademi Yetesayensi YaseShayina (i-CAS)’, ‘Lilabhorethri Lelibalulekile Le-Shanghai Caryoviqure-Super-Cryococdugen Buchwepheshe' kanye 'neLabhorethri Lebalulekile yaseShanghai Yekudvonsa Ngemandla E-Cryogenic Nebuchwepheshe Bemigodzi Lesetulu Yemvamisa'. Shanghai Labhorethri Lebalulekile Yebuchwepheshe Bemgodzi Wemvamisa Lephakeme Yekushisa Lokuphansi'. Tincenye te-inverter letitfutfukiswe kulokubambisana titawusetjentiswa kuma-accelerators lahamba ngemandla lamakhulu emalabhorethri langetulu, latawuniketa sisombululo lesibalulekile selucwaningo lolusetjentisiwe lwetebucwepheshe benuzi.
II. Indlela Yekubambisana Nendlela Yekusebenta
Ngesikhatsi sekubambisana, bobabili labatsintsekako bagcine kukhulumisana lokusedvute nekubambisana. Ngemihlangano levamile, imibiko yenchubekelembili kanye nekushintjana endzaweni, bobabili labatsintsekako bacinisekisa kutsi yonkhe imininingwane yetebuchwepheshe iyavisiseka futsi iyabonakala kahle. Lendlela yekuchumana lesebenta kahle ayigcini nje ngekusheshisa inchubekelembili yekutfutfukisa umkhicito, kepha futsi yenta ncono lizinga kanye nekusebenta kwemikhicito.
III. Bucwepheshe Bekuhlanganisa kanye neMiphumelelo
I-receiver ye-shortwave lesetulu leyentiwe ngekwemvelo yi-XST ye-ASTRI inekuhlanganiswa lokukhulu kwemvamisa (lekhona kutfola timphawu te-shortwave temabhande lamanyenti emvamisa), likhono lekunciphisa lelinemandla (kungakhatsaliseki kutsi kuguculwa kwe-amplitude (AM), kuguculwa kwemvamisa (FM) noma kuguculwa kwe-single-sideband kungayitfola ngendlela lefishane lokucuketfwe), kanye nekuvumelana lokucinile (kuvumelana netimphawu tekusakateka kwesiginali yemagagasi lamafishane ngaphansi kwetimo tesimo selitulu letehlukene kanye netikhatsi tesikhatsi). (ikhona kujwayela timo tesimo selitulu letehlukene kanye netikhatsi tetimphawu tekusakateka kwesiginali yemagagasi lamafishane) kanye naletinye timphawu tebuchwepheshe kanye netinzuzo.
Solo kwemukelwa kwemagagasi lamafishane e-XST afakwe elabhorethri, ancobe ludvumo loluhle loluvumelanako lwemakhasimende ngekusebenta kwawo lokuhle kakhulu kanye nekusebenta kwetindleko letisetulu, futsi agcugcutele kusungulwa kanye nekutfutfukiswa kwesayensi netebucwepheshe benuzi, kwenta iminikelo lebalulekile enchubekelembili yesayensi netebucwepheshe kanye nekwakhiwa kwekuvikela kwavelonkhe kulelive.
