RF High Power BroadBand Test Systems Programmable Attenuators
Polokalama attenuators o masini faaeletonika e mafai ai mo le pulea faafuainumera ma fetuunaiga saʻo o tulaga attenuation.
E masani ona aofia ai se faasologa o attenuators pulea e faailo numera. Polokalama attenuators e mafai ona pulea e ala i le RS-232 poʻo fesoʻotaʻiga USB, faʻafaigofie ona tuʻufaʻatasia i faiga tetele. Pe a faatusatusa i attenuators fesuiaʻi tusi, latou te maua ai le saʻo maualuga ma le toe faʻaleleia, lea e aoga tele i talosaga e manaʻomia ai le faʻaogaina masani poʻo le faʻaogaina lelei.
O attenuators polokalame e iai uiga nei:
1. Polokalama: E mafai ona fa'aogaina fa'ailoga numera po'o analog e fa'atonutonu ai le fa'aitiitia, la'a, ma le fesuia'i i le va o la'asaga ma faiga fa'aletonu.
2. Faʻamautu: E i ai se tau faʻamalieina mautu ma e masani lava e le afaina i le vevela poʻo isi tulaga tau le siosiomaga.
3. Faʻatinoga maualuga: i le tele o faʻainisinia eletise eletise, o loʻo i ai le fetaui lelei o le Electromagnetic, tutusa, maualalo le faʻaogaina o le gau ma isi faʻatinoga sili ona lelei.
4. Miniaturization: E mafai ona tuʻufaʻatasia i tamaʻi afifi ma e laʻititi laʻititi.
E masani ona fa'aogaina fa'apolokalame fa'apolokalame fa'ata'ita'iga fa'ata'ita'iga fa'alelalolagi fa'ailo o le lalolagi ma fa'amaonia le fa'atinoga o masini i lalo ole tulaga malosi fa'ailoga eseese. E fa'aaogaina lautele i talosaga, faiga fa'afeso'ota'i uaealesi, ma le fa'ata'ita'iina ma le su'ega o fa'aeletonika ma vaega.
Aemaise lava, e aofia ai:
1. Feso'ota'iga faiga: Fa'aoga i le fetu'una'iga o le malosi fa'ailo uaealesi e 'alofia ai le a'afiaga o fa'ailoga malolosi tele i masini ma faiga.
2. Fua o meafaigāluega: Fa'aaogā mo le fa'asa'o sa'o o taimi ma fa'alumaina e fa'afetaui ai mana'oga o su'ega.
3. Aerospace: I vaalele, tekinolosi avanoa, ma meafaigaluega faʻatautaia, e faʻaaogaina mo le faʻavasegaina o le taamilosaga ma le faʻaogaina o le attenuation.
4. Leitio: E faʻaaogaina i le leitio alamanuia e faʻatonutonu ma attenuate faailoilo.
Qualwavee tu'uina atu fa'alāpotopotoga fa'alāpotopotoga ma fa'aolaola maualuga fa'apolokalame-attenuators i alaleo e o'o atu i le 40GHz. O le laʻasaga e mafai ona 0.5dB ma le attenuation range e mafai ona 80dB pe sili atu. O tatou polokalame-attenuators e fa'aaogaina lautele i le tele o eria.
