Zvinonyanya kukosha zveFU-1000D 1kW FM Transmitter

Iyo ine simba yedhijitari yekugadzirisa tekinoroji inogona kugadzira yakakwana CD-yakafanana nekunzwa maitiro kwauri
Kugamuchirwa kweFPGA yekugadzirisa tekinoroji inoona yakakura-chiyero dhijitari kugadzirisa
Direct digital frequency synthesis (DDS) tekinoroji inogona kumhanyisa kusvika ku5G kusvika pakakwirira
Iyo huru controller inotora tekinoroji yemicroprocessor (ARM), ine kuvimbika kwakanyanya
Yakagadziridzwa yakawanda-odhiyo sosi yekuisa inovandudza zvakanyanya maneuverability yetransmitter (transmitter inogona kusarudzwa otomatiki zvinoenderana nekutanga)
Yakanyanya kukoshesa AES / EBU dhijitari odhiyo chiratidzo chekuisa
Chechipiri chakakosha analog stereo analog odhiyo yekuisa chiratidzo
Chechitatu chakakosha MPX Stereo composite chiratidzo chekuisa
Single RDS kana SCA subcarrier yekuisa sarudzo dzekutsigira
FM Synchronous Broadcast Transmitter inosimudzira sarudzo dzekutsigira
Zero Drift AGC inodzorwa simba rekubuda
Alarm uye dziviriro ye-over-current, over-voltage, over-temperature, overpower uye kumira wave ratio inovandudza transmitter yambiro
Pamberi pekubata kiibhodhi yekuisa kuti uvandudze ruzivo rwemushandisi
Kuratidzwa kweOLED kunoita kuti-chaiyo-nguva data iratidze kupfava uye kujeka
NeTCP / IP uye RS232 kutaurirana interface, kushanda kweiyo transmitter kunowedzerwa
Iyo 19-inch yakajairwa chassis ine hurefu hwe2U inogona kuzadzisa zvaunoda zvachose
