Modular construction. Conventional cooling. AGC and ALC controls. 3-slope linearity precorrection. Excellent noise figure. Programming of local oscillator from front panel. Pre-set for precision OFFSET.

SCT 100U/S 10W UHF STEREOTRANSMITTER

Multifunction digital display. Soft-start circuit. Low power consumption. Economy circuit incase of input signal lack. SAW vestigial filter. Sync restore (SCT). Group delay precorrection (SCT). Automatic white level and sync limiter(SCT). Multistandard modulator (SCT). Available in stereo/dual sound version. ICPM and differential phase precorrectoroption available. Possibility of use of common andseparate carriers.

The transmitters andtransposers in this series are characterized by high performance andcapability and by excellent linearity over the entire band thanks tothe optimization of the RF circuits.
A high degree of reliability is guaranteed, moreover, by the use ofoversized cooling devices and by control circuits operated by modernmicroprocessor technologies.

Detail of SCT series transmitter

These units are used aslow-power transmitters or transposers or as driver stages foramplifiers of greater power and are available in 2 to 20 W versions.The excellent spectral purity of the conversion oscillator endows theseunits with an excellent signal/noise ratio of the radiated signal.

The synthesized localoscillator allows easy, rapid changing of the transmission channel fromthe front panel.

The offset option allowsfrequency shifts in 1 Hz (CCIR) or 0.999000999 Hz (FCC) steps foroperation in "precision offset" or "isofrequency" mode in the varioustelevision standards. The units are equipped with an input connectorfor an external reference signal at 5 MHz and with a 25-pole connectorfor the remote monitoring of operating parameters.
