Channel/IF Converters
General. The TXI Series TV down-converters are used to transpose the RF TV signal from I, III, IV or V frequency band to an IF signal compatible with all A/V modulators in the market.
Digital compatible. The TXI converters are fully compatible with analog or digital TV signals.
Synthesized. The input RF channel can be easily set by an agile dip-switch selector.
Broadband. To change the input channel it’s simply necessary to retune the input channel filter. All the other parts are broadband and don't need any retuning.
Offset configuration is available on request with precision up to 1 Hz.
Modular construction. For easy maintenance all circuits are built up in easily interchangeable plug-in modules.
Solar cells/battery power supply. Vdc power supply option is available for battery or solar cells operations.
Fully compatible with all international television standards.
Meets or exceed all FCC and CCIR requirements.
