Product Description
CATV Equipment Agile Modulator

1. Summary
Adjacent Channel Agile Modulator is headend equipment for adjacent channel modulation of image and acoustical signals. Carrier frequency of output signal can be changed with internal phase-locked loop local oscillator circuits controlled by microcomputers. Medium frequency treatment technique and phase locked loop technology are adopted to improve frequency stability and reduce signal distortion. It's the best choice for large and medium-sized CATV systems.

2. Performance Characteristic
1 Medium frequency treatment technique and dual-phase locked loop technology for CPU control are adopted to improve frequency stability.
2 Number of output channels are within the limit of 48~550/750/870MHz. Standard channels and added channels were installed.
3 Carrier frequency or each channel is within the limit of 48~550/750/870MHz. 4 standards of sound carrier frequency: 4.5, 5.5, 6.0, 6.5MHz.
N The vision signal modulation, audio deviation, A/V ratio and output level can be adjusted on the front panel.
4 Independent RF Power Amplifiers are inside. The output level is up to over 110dBμ V.
5 It's easier to operate, because of the digital channel number of front panel, the uplink of back panel, memory channels and power failure memory function.
6 Output power of B machine is 48~550MHz. Output power of C machine is 48~750MHz. Output power of D machine is 48~870MHz.
7 Two lines 20-bit LCD display is on front panel. Add medium frequency interfaces.
