Mean-power digital TV transmitter FTV-220D |
FTV-220D front face
COFDM-modulator SFN front face
* Transmitter DVB-T, H (2k, 4k, 8k, MFN or SFN mode)
* Average power 100W
* It consists of transmitter FTV-220D and COFDM-modulator SFN (when organizing single-frequency network)
* If network is multifrequency (MFN) than modulator COFDM is included into composition of transmitter FTV-220D
* Control of COFDM modulator's modes is exercised from computer
* Automatic power control
* Displaying of output power, antenna-feeder path VSWR, supply voltage and final stage temperatures + emergency operation
displaying when having an emergency
* Protection of antenna-feeder path by VSWR
* SFN mode
