Ordinary Agile Channel Modulator

タイトルまたは説明

Channel Agile modulator: Features: 1. Automatic follow filter with output, low out of band noise; Be good for using several units at the same time, avoid system CNR worse. 2. Intermediate frequency modulated, twice mix style, small spur out of 3. Audio intermediate frequency, image high frequency and MCU technique is applied to audio, local oscillator to ensure high frequency stability. 4. Intermediate frequency and output. 5. Output impulse adopts modularization and SMT technology is applied to MMIC circuit, the unit is in high security. 6. LCD display frequency, use up and down to choose any preference frequency. 7. Convenient control, all frequency level adjustments are designed ahead; output level, A/V, volume size and video index all adjust *2 poles variable separately. 8. High dependable and high dynamic powers are applied to part of the source of voltage. 9. We can make different channels according to the customer’s requests. MODEL the ****0M modulator function is perfect, the capability is high, and the security is nice, which is the preference equipment to construct MATV, SMATV or the CATV system.
