500W DVB-T/T2 UHF TRANSMITTER
Product Description
UHF Outdoor Terrestrial DTV Transmitter
The Gospell GT-5900A-500 indoor terrestrial digital television broadcasting transmitter operates at 470-702MHz. It has flexible configuration and adheres to the consistent high index, high stability and high reliability of Gospell products. It can fully meet the needs of multifrequency transmission and large regional coverage. It is especially suitable for terrestrial digital TV networks with complex terrain and wide coverage.
The device has the advantages of advanced system design, low noise, high working efficiency, superior anti-interference ability, simple structure and small size. It fully supports DTMB, CMMB, DVB-T / T2, ISDB-T, ATSC-T and other digital TV standards, and it has good flexibility and applicability in practical engineering.
Main Features Strong applicability The operating frequency: 470 ~ 702MHz; Support single channel and broadband transmission. Support a variety of modulation standards, including: DTMB, CMMB, DVB- T/T2, ATSC-T and ISDB-T, etc. Modular design, easy to install, maintain and upgrade. Support complete machine \ preamplifier unit \ exciter 1 + 1 backup. High efficiency High efficiency LDMOS power amplifier and linear circuit design are adopted to further reduce the power consumption of the equipment. The built-in adaptive pre-correction module (option) supports broadband pre correction, which can greatly improve the working efficiency and output signal quality of the transmitter. High stability Support two power control modes of ALC and AGC (optional) to stabilize output power. The stability of the device is greatly enhanced by using protection mechanisms such as over-temperature, overcurrent, overexcitation and standing wave. Perfect delay start technology can effectively avoid the damage of burst signal to transmitter. High performance Excellent output signal quality fully meets the requirements of transmission system for signal quality. Good out of band indicators are particularly suitable for use in complex electromagnetic environments. Sufficient power margin to meet customer requirements for transmission power. Easy to use Adopt true color TFT touch screen, with friendly human-machine interface and convenient operation Support local and remote monitoring Support Web management and GPRS remote monitoring (option) Block Schematic Diagram of Equipments
