16 Way Agile Adjacent Modulator (DT-AAM-16W4U),16 in 1 adjacent
modulator is one of CATV headend equipment. It realizes 16 channels
video/audio signal’s RF modulation at any channel in 47~870MHz.
The modulator permits to input 0.7~1.4V video signal source signal,
such as satellite receiver, TV camera or TV demodulator.
16 Way Agile Adjacent Modulator (DT-AAM-16W4U),16 in 1 adjacent modulator is one of CATV headend equipment. It
realizes 16 channels video/audio signal’s RF modulation at any channel in 47~870MHz. The modulator permits to input
0.7~1.4V video signal source signal, such as satellite receiver, TV camera or TV demodulator. Under condition of normal
frequency deviation, audio signal 0.775V±10dB/10KΩ can input through external continuous modulation.Output level:
≥100dBµV,Return loss:≥12dB,Out-of-Band Output Rejection:≥60dB,Output level adjusting range:0~20dB,Dimension:
483×210×176MM,Power supply:AC 110~260V,American Standard or European Standard Power Plug is optional.
★Features
⊙Any 16 way channels in 47~870MHz frequency;
⊙Mid-frequency modulation, adopts SAW filter process, with good performance;
⊙Select output channels in front panel pressing button, digital tube frequency display;
⊙Video modulation depth, audio frequency deviation, RF output level, A/V front panel adjustable;
⊙Mid-frequency and local oscillator both adopt phase-locked loop technique, with high frequency stability;
⊙Adopts perfect switching power supply, which can ensure the equipment stable working all throughout the year.
