Digital Frequency Converter

タイトルまたは説明

Features: 1. This product is to convert RF signal of a certain channel to another channel, and process this signal within the same frequency. 2. This product can convert IF into RF, as well as RF to IF. 3. It is can be used to process both digital and analog signal. 4. With RF Auto Gain Control circuit (AGC), ensuring the stability and reliability of the headend system. 5. LCD to display various performance parameters in real-time. 6. To control and output signal level with micro computer. 7. Adjacent frequency design, IF processing, SAW, good interference suppression 8. LO adopts unique phase locked loop, with low phase noise, low phase jitter and low BER. It is suitable for digital signal frequency conversion. 9. Both down and up conversions adopt high quality and performance dual balanced mixed frequency, with fine linearity, low distortion and less clutter. *0. RF and IF circuits adopt multipoint channel filter to reduce the interference from the outside signal. *1. RF output adopts module amplification to ensure the dynamics and parasitism restrain of RF output. *2. *9 standard structure, independent power supply, matching flexible, elegant appearance, firm structure and excellent electromagnetic shielding, easy to use and maintain.
