SK-6000M |
1. High quality saw filter process, low noise figure can avoid system CNR worse.
Suitable for professional CATV system.
2. Intermediate frequency process, low spur out of band.
3. Audio intermediate frequency process, video high frequency process. MCU technique
is applied to audio, local oscillator to ensure high performance and stability.
4. Intermediate frequency input and output for further operation.
5. Output impulse adopts modularization design and SMT technology is applied to MMIC
circuit, the unit is in high reliability.
6. LED Display frequency, use up and down button to choose any preference frequency.
7. Convenient control, frequency level adjustment is on front panel; output level, A/V,
volume and video index all adjusted by 32 steps variable separately.
8. High efficiency SMPS.
9. We can offer different TV system standard according to the customer’s need.
