CTX TV Exciters

The CTX Analog TV Multistandard Exciter has top class performances in Analog TV modulation to be perfectly used as a stand alone low power compact transmitter or as an exciter for higher power analog TV transmitters.

Graphic LCD Control
All CTX exciters are equipped with a powerful Graphic LCD Control system. Front panel instant frequency programmability, RF power settings, audio settings, deviation controls, alarms status are only some of the main facilities available in the graphic display.

5-10-20 Wps
The CTX exciters are available with 5-10-20 Wps maximum output power. The output RF level is continuously adjustable from 0 to full nominal power simply using the LCD front control panel.

High frequency stability
High frequency stability in short and long terms is assured by Digital Phase Locked Loop circuits with extremely low drift oscillators.

Precision Offset
Precision offset facility down to 1 Hz in the CTX exciter using the DDS technology is available as option. Offset setting available from front panel LCD graphic display.

Ultra High Performance Precorrector
Ultra High Performance Precorrector with quadrature (I/Q) corrections and 12 specific non-linearity adjustments to easily optimize intermodulations and proper sync level. White-Gray-Black-Sync. very high performances precorrection to be able to get perfect modulation also with class AB non linear high power amplifiers.

Dual-Cast Ready and Digital Ready
The CTX exciter is suitable to work in dual cast systems thanks to its internal ADC switching system with possibility to integrate external digital modulation units with direct front panel management.

Electronic protections
The CTX exciters are automatically protected in case of load mismatching (VSWR) or transmitting frequency error (Unlocked oscillator) or over temperature. Every alarm event is displayed by front panel ALARM led for immediate indication: more details on the occurred alarm are available in the LCD graphic front panel display or remotely (Remote Control option).

Output band pass filter (optional)
When CTX exciters are used as stand alone TV transmitters an highly selective output channel filter is needed. It assures a pure RF spectrum, according to the all international standards and requirements.This filter is available as option.

Power supply
High efficiency switching mode power supply gives greater reliability and reduces the power consumption.
