 MAIN FEATURES
 
  • Modular construction.
  • Convectional or forced air cooling.
  • AGC and ALC controls.
  • 3-slope linearity precorrection.
  • Excellent noise figure.
  • Channel change from front panel (optional).
  • Pre-set for precision OFFSET.
  • Multifunction digital display.
  • Soft-start circuit.
  • Low power consumption.
  • Economy circuit in case of input signal lack.
  • SAW vestigial filter.
  • Incorporated power limiter.
  • Sync restore (SCT).
  • Automatic white level and sync limiter (SCT).
  • Multistandard modulator (SCT).
  • Available in stereo/dual sound version.
  • Possibility for use of common and separate carriers.
  • Digital-ready transposers.

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 to20 W versions.

The excellent spectral purity of the conversion oscillator endows theseunits 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 shiftsin 1 Hz (CCIR) or 0.999000999 Hz (FCC) steps for operation in“Precision Offset” or “Isofrequency” modes in various televisionstandards.

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.
