Zvishandiso Zvinogona Kurongwa USB RF Dhijitari Nhanho USB Inodzorwa
Zvishandiso zvinogadziriswa zvemagetsi zvinobvumira kudzora kwedhijitari uye kugadzirisa kwakarurama mazinga ekuderedzwa kwesimba.
Kazhinji dzine ma "attenuator" akatevedzana anodzorwa nemasaini edhijitari. "Programmable step attenuators" anogona kudzorwa kuburikidza neRS-232 kana USB interfaces, zvichiita kuti zvive nyore kubatanidzwa mumasisitimu makuru. Kana zvichienzaniswa nema "manual variable attenuators", anopa kururama kwakanyanya uye kugona kudzokorora, izvo zvinobatsira zvikuru mumapurogiramu anoda kugadziriswa nguva nenguva kana kugadziriswa zvakanaka.
Zvigadziriso zveRF zvinogadziriswa zvine hunhu hunotevera:
1. Kugona Kugadzira Mapurogiramu: Masaini edhijitari kana eanalog anogona kushandiswa kudzora kudzika, kukwira, uye kuchinja pakati pemazinga akasiyana ekudzika uye mamodhi.
2. Kugadzikana: USB RF Digital Step Attenuator ine kukosha kwakasimba kwekudzikisa tambo uye kazhinji haikanganisike nekupisa kana mamwe mamiriro ekunze.
3. Kushanda kwepamusoro: Munzvimbo dzakasiyana-siyana dzemagetsi emagetsi, USB attenuator ine Electromagnetic compatibility yakanaka, yakaenzana, ine insertion loss shoma uye mamwe mashandiro akanaka kwazvo.
4. Miniaturization: USB controlled attenuator inogona kubatanidzwa mumapakeji madiki uye ine saizi diki kwazvo.
Zvidziviriri zvinodzorwa neUSB zvinodzorwa neUSB zvinowanzo shandiswa kutevedzera mamiriro ezvinhu ekuderedza masaini chaiwo uye kuona mashandiro emidziyo pasi pemamiriro akasiyana esimba remasaini. Zvinoshandiswa zvakanyanya mumapurogiramu, masisitimu ekutaurirana asina waya, uye dhizaini nekuyedzwa kwemaseketi emagetsi nezvikamu.
Kunyanya, attenuator yeRF inorongwa inosanganisira:
1. Sisitimu yekutaurirana: Shandisa attenuator inorongwa mukugadzirisa simba remasaini asina waya kudzivirira kukanganiswa kwemasaini akasimba zvakanyanya pamidziyo nemasisitimu.
2. Kuyera Chishandiso: Shandisa chinodzivirira matanho chinogadziriswa kuti chigadzirise frequency chaiyo uye chidzikise kuti chienderane nezvinodiwa pakuedza.
3. Mundege: Mundege, tekinoroji yemuchadenga, uye michina yekufambisa, USB RF digital step attenuator inoshandiswa pakuenzanisa circuit uye kudzora attenuation.
4. Redhiyo: Chinobatidza masaini cheUSB chinoshandiswa muindasitiri yeredhiyo kudzora nekuderedza masaini.
Qualwaveinopa bhendi rakakura uye ma "programmable-attenuators" emhando yepamusoro pa "frequency" inosvika 40GHz. Danho racho rinogona kuva 0.5dB uye "attenuation range" rinogona kuva 80dB kana kutopfuura. Ma "programmable-attenuators" edu anoshandiswa zvakanyanya munzvimbo dzakawanda.
