MOD-SCM08 is a mono, double side band (DSB) TV modulator designed to operate with A/V household devices – video recorders, DVD players, satellite receivers, CCTV camera, etc. The TV modulator converts low frequency signal (Audio and Video) from A/V devices into high frequency signal in TV channel range. Modulated signal may be transmitted for long distances thorough a coaxial cable, connected to the antenna input or split into a few TV sets with a splitter. The modulator also makes it possible to sum its high-frequency signal and other HF signals (eg from a Tv antenna). Signal summing effected in the standalone configuration modulator may be supplied locally from 12V/250 mA external power supply. In the other case, the modulator uses the SCM08 power supply. The power is supplied throught the DC IN port or the RF output using a coaxial cable and a power inserter. Then the power is also supplied to the DC port from which a CCTV can also be supplied. MOD-SCM08 can operate in the frequency range from channel S3 to ch69(I South African standard) or from channel S1 to ch69 (B/G standard). It is possible to enable the TEST signal which facilitates programming of the selected TV signal in a TV set. Modulator programming involves putting the keys of 10-segment switch in required position. Audio and Video inputs and RF output have the gain control of respectively, input and output signal. The POWER LED signals the modulator status: continuously lit – correct operating parameters fast flashing – incorrect operating parameters slow flashing – – test signal on SKU: MOD-SCM08 Categories: Headends, Small Commercial Applications, Television Tag: Modulator
