Screen Service 2-20 W ps TELEVISION EXCITERS

The transmitters and transposers in this series are characterized by high performance and capability and by excellent linearity over the entire band thanks to the optimization of RF circuits. A high degree of reliability is guaranteed, moreover, by the use of oversized cooling devices and by control circuits operated by modern microprocessor technologies.These units are used as low-power transmitters or transposers or as driver stages for amplifiers of greater power and are available in 2 to 20 W versions. The excellent spectral purity of the conversion oscillator endows these units with an excellent signal/noise ratio of the radiated signal. The up-converter option allows easy, rapid changing of the transmission channel from the front panel. The Offset option allows frequency shifts in 1 Hz (CCIR) or 0.999000999 Hz (FCC) steps for operation in “Precision Offset” or “Isofrequency” modes in various television standards. The units are equipped with an input connector for an external reference signal at 5 or 10 MHz. A series of different interfaces for the remote monitoring of operating parameters are available as well.
