Tsananguro yeChigadzirwa
1. NHANGANYAYA
AH2401H imodulator ye24 modular frequency fixed-channel modulator. Ichave nemasaini eaudio nemavhidhiyo anosvika makumi maviri nemana mumugwagwa une masaini eRF eTV channels makumi maviri nemana. Chigadzirwa ichi chinoshandiswa zvakanyanya mumahotera, muzvipatara, muzvikoro, mukudzidzisa kwemagetsi, mumafekitori, mukutarisa kuchengetedzeka, mumavhidhiyo eVOD pane zvinodiwa nedzimwe nzvimbo dzevaraidzo, kunyanya pakushandura analog yeTV yedhijitari, uye musystem yekutarisa pakati.
2. ZVINHU ZVINHU
- Yakagadzikana uye yakavimbika
- AH2401H yechiteshi chimwe nechimwe yakazvimirira zvachose, kushanduka kwegadziriro yechiteshi
- Mifananidzo ine mafrequency akawanda uye RF local oscillator MCU inoshandiswa, kugadzikana kwemafrequency uye kunyatsorurama kwakanyanya
- Basa remachipisi ese edunhu akabatanidzwa rinoshandiswa, kuvimbika kwakazara
- Simba remhando yepamusoro, kugadzikana kwemaawa manomwe nehafu

Panera repamberi
1. Kugadziriswa kwemazinga ekubuda kweRF—Knob, mazinga ekubuda kweRF anogadziriswa
2. Kugadziriswa kweAV ratio—Knob inogadzirisa kubuda kweA / V ratio
3. kugadzirisa vhoriyamu—Kiyi yekugadzirisa saizi yevhoriyamu inobuda
4. kugadzirisa kupenya—Kiyi yekugadzirisa kupenya kwemufananidzo unobuda
Panera rekumashure
A. Chiteshi chekuedza chekubuda: Chiteshi chekuedza chekubuda kwevhidhiyo, -20dB
B. RF output: Multiplexer module modified, mushure mekusanganisa RF output
C. Mutemo wekubuda kweRF: Knob, nhanho yekubuda kweRF inogadziriswa
D. Kubuda kwemagetsi mu cascade
Kuisa ma modulators akawanda panzvimbo imwe chete, unogona kukanda magetsi kubva ipapo kuenda kune mamwe ma modulator emagetsi kuti uderedze kushanda kwemagetsi; chenjerera kuti usakanda magetsi kupfuura mashanu kudzivirira magetsi akawandisa.
E. Kupinda Kwesimba: AC 220V 50Hz/110V 60Hz
F. RF input
Kupinza kweG. HDMI
