Attenuators nwere ike ime ihe USB RF Digital Nzọụkwụ USB na-achịkwa
Attenuators programmable bụ ngwaọrụ eletrọnịkị nke na-enye ohere maka njikwa dijitalụ na ngbanwe ziri ezi nke ọkwa attenuation.
Ha na-enwekarị usoro nke attenuators nke akara dijitalụ na-achịkwa. Enwere ike ijikwa ndị attenuators nzọụkwụ mmemme site na RS-232 ma ọ bụ oghere USB, na-eme ka ọ dị mfe itinye n'ime sistemụ buru ibu. E jiri ya tụnyere ntuziaka mgbanwe attenuators, ha na-enye elu izi ezi na repeatability, nke bara ezigbo uru na ngwa na-achọ ugboro ugboro mgbanwe ma ọ bụ mma-nlegharị anya.
Ndị attenuators RF nwere mmemme nwere njirimara ndị a:
1. Programmability: Enwere ike iji akara dijitalụ ma ọ bụ analog na-achịkwa attenuation, steepụ, na ịgbanwee n'etiti ọkwa dị iche iche attenuation na ụdịdị.
2. Nkwụsi ike: USB RF Digital Step Attenuator nwere uru attenuation kwụsiri ike ma ọ naghị emetụta ya na ọnọdụ okpomọkụ ma ọ bụ ọnọdụ gburugburu ebe obibi ndị ọzọ.
3. Ịrụ ọrụ dị elu: N'ọtụtụ dịgasị iche iche nke injinia electromagnetic, USB attenuator nwere ezigbo ndakọrịta Electromagnetic, nha anya, nkwụsị ntinye dị ala na arụmọrụ ndị ọzọ dị mma.
4. Miniaturization: USB na-achịkwa attenuator nwere ike itinye n'ime obere ngwugwu ma nwee obere nha.
A na-ejikarị eriri USB na-achịkwa programmable attenuators iji ṅomie ọnọdụ nhụta mgbama n'ezie na nyochaa arụmọrụ nke ngwaọrụ n'okpuru ọnọdụ ike mgbaama dị iche iche. A na-eji ha eme ihe n'ọtụtụ ebe na ngwa, usoro nkwurịta okwu ikuku, na imewe na ịnwale sekit na ihe ndị dị na eletrọnịkị.
Kpọmkwem, ihe mmemme RF attenuator gụnyere:
1. Usoro nzikọrịta ozi: Jiri attenuator programmable na-edozi ike mgbaama ikuku iji zere mmetụta nke mgbaàmà siri ike na ngwaọrụ na sistemụ.
2. Instrument nha: Jiri programmable nzọụkwụ attenuator maka kpọmkwem ugboro ukpụhọde na attenuation izute ule chọrọ.
3. Aerospace: Na ụgbọ elu, teknụzụ ohere, na akụrụngwa igodo, USB RF digital step attenuator na-eji maka nhazi sekit na njikwa attenuation.
4. Redio: A na-eji USB attenuator na ụlọ ọrụ redio na-achịkwa ma na-ebelata akara.
Qualwavena-enye nnukwu band na oke ike dị elu programmable-attenuators na ugboro ugboro ruo 40GHz. Nzọụkwụ nwere ike ịbụ 0.5dB na attenuation nso nwere ike ịbụ 80dB ma ọ bụ ọbụna karịa. Anyị programmable-attenuators na-ọtụtụ ebe n'ọtụtụ ebe.
