Nā Attenuators Programmable USB RF Digital Step USB Controlled
ʻO nā attenuators programmable he mau mea uila e ʻae ai i ka mana kikohoʻe a me ka hoʻoponopono pololei ʻana i nā pae attenuation.
ʻO ka maʻamau, aia lākou i kahi moʻo o nā attenuators i kāohi ʻia e nā hōʻailona kikohoʻe. Hiki ke hoʻokele ʻia nā attenuators ʻanuʻu hiki ke hoʻonohonoho ʻia ma o RS-232 a i ʻole nā interface USB, e maʻalahi ai ka hoʻohui ʻana i nā ʻōnaehana nui. Ke hoʻohālikelike ʻia me nā attenuators loli manual, hāʻawi lākou i ka pololei kiʻekiʻe a me ka hana hou ʻana, he mea pono loa ia i nā noi e pono ai ka hoʻoponopono pinepine a i ʻole ka hoʻoponopono maikaʻi ʻana.
Loaʻa i nā mea hoʻēmi RF hiki ke hoʻonohonoho ʻia nā ʻano penei:
1. Programmability: Hiki ke hoʻohana ʻia nā hōʻailona kikohoʻe a analog paha e kāohi i ka attenuation, ka hehi ʻana, a me ke kuapo ʻana ma waena o nā pae attenuation like ʻole a me nā ʻano.
2. Paʻa: Loaʻa i ka USB RF Digital Step Attenuator kahi waiwai attenuation paʻa a ʻaʻole pinepine ia e hoʻopilikia ʻia e ka mahana a i ʻole nā kūlana kaiapuni ʻē aʻe.
3. Hana kiʻekiʻe: Ma nā ʻano ākea o nā kahua electromagnetic ʻenekinia, loaʻa i ka USB attenuator ka hoʻohālikelike Electromagnetic maikaʻi, ke kaulike, ka pohō hoʻokomo haʻahaʻa a me nā hana maikaʻi loa ʻē aʻe.
4. Hoʻonui liʻiliʻi: Hiki ke hoʻohui ʻia ka attenuator i kāohi ʻia e USB i loko o nā pūʻolo liʻiliʻi a he liʻiliʻi loa kona nui.
Hoʻohana pinepine ʻia nā mea hoʻēmi papahana USB i kāohi ʻia e hoʻohālike i nā hiʻohiʻona hoʻēmi hōʻailona o ke ao maoli a hōʻoia i ka hana o nā hāmeʻa ma lalo o nā kūlana ikaika hōʻailona like ʻole. Hoʻohana nui ʻia lākou i nā noi, nā ʻōnaehana kamaʻilio uea ʻole, a me ka hoʻolālā a me ka hoʻāʻo ʻana o nā kaapuni uila a me nā ʻāpana.
ʻO ke kikoʻī, ʻo ka attenuator RF programmable e komo pū ana me:
1. ʻŌnaehana kamaʻilio: E hoʻohana i ka attenuator programmable i ka hoʻoponopono ʻana i ka ikaika hōʻailona uea ʻole e pale aku i ka hopena o nā hōʻailona ikaika loa ma nā polokalamu a me nā ʻōnaehana.
2. Ana o ka mea hana: E hoʻohana i ka attenuator ʻanuʻu hiki ke hoʻonohonoho ʻia no ka hoʻoponopono alapine pololei a me ka attenuation e hoʻokō i nā koi hoʻāʻo.
3. Aerospace: I loko o ka mokulele, ʻenehana lewa, a me nā lako hoʻokele, hoʻohana ʻia ka USB RF digital step attenuator no ka calibration circuit a me ka mana attenuation.
4. Lekiō: Hoʻohana ʻia ka mea hoʻēmi USB ma ka ʻoihana lekiō e hoʻoponopono a hoʻēmi i nā hōʻailona.
QualwaveHoʻolako i ka band ākea a me nā programmable-attenuators ākea kiʻekiʻe ma nā alapine a hiki i ka 40GHz. Hiki i ke ʻanuʻu ke 0.5dB a hiki i ka laulā attenuation ke 80dB a ʻoi aku paha. Hoʻohana nui ʻia kā mākou programmable-attenuators ma nā wahi he nui.
