Conventional cooling. AGC and ALC controls. Excellent noise figure.
Interchangeable modules for fast configuration intransmitter or transposer versions. Linearity precorrection. Agile programming of channel from front panel. 10 kHz (FCC) or 10.45 kHz (CCIR) steps for offsetoperation. Multifunction digital display. SAW vestigial filter. Luminance/chrominance delay precorrection(transmitter). Multistandard modulator (transmitter)

The distinguishing features of thetransmitters and transposers in the SCE series are the excellentperformance capability and quality/price ratio that characterize them.They consist of an up-converter and the subsequent amplification stagesto which are added a modulator board and a down-converter which areinterchangeable so as to be able to transform a transmitter into atransposer and vice versa in a very short space of time.

The units in this series are fully agile,meaning that it is possible to change the transmission or receptionchannel directly from the front panel without performing any kind ofcalibration.
Offset operation is allowed by means of frequency shifts in 10 kHz(FCC) or 10.45 kHz (CCIR) steps.

The substantial dynamic capability of theAGC and ALC circuits guarantees high stability of the output level evenin the presence of considerable variations in the input signal.

The transmitters and transposers of the SCEseries are much lighter and more compact (only 1 standard 19" unit) andare available in 2 and 10 W p.s. output power versions.
A practical LED display allows the visualization of all the operatingparameters of the unit.
