500w Indoor Digital TV Broadcast Transmitter

500w Indoor Digital Tv Broadcast Transmitter

Digital television uses a digital signal instead of a radio signal to transmit programmes. Information in a digital signal is transmitted as 1s and 0s—binary bits—which are put back together at the receiving end to form picture and sound. These signals offer the potential for more channels and better picture quality.

Know the distance between your home and the TV transmitters broadcasting in your area. Check the one for all aerial selector to find the nearest TV Transmitter. Reception not only depends on distance from a broadcast tower, but also on the terrain and the surroundings (nearby houses, buildings, trees, etc.).

Overview:
This product is the all solid-state Single-channel TV Transmitter, it adopts professional TV exciter, and it can use the
single/duel exciter configuration, switching automatically.
This transmitter has a variety of linear and non-linear pre-correction function, carrier frequency offset, and precision bias
(with external precision reference source) function.
It can prefabricate and control the half-power output, and it has remote control telemetry interface.
The power amplifier used LDMOS FET, the analog and digital are both compatible, and it used high-quality switch parallel power.
The power amplifier and power supply are both used hot-plug devices.
The power loss and standing wave of the one-time synthesis power combiner is small.
The module of power amplifier display the working parameters in real-time.
The whole machine has the protection of over-current, over temperature, over power and over-standing wave ratio.
The master touch screen displays the working parameters of the whole machine and the module of power amplifier (PA) in real-time.
The 200W transmitter is installed in one 19inch chassis; it’s suitable for medium or small TV station.

Features:
Supported Standards DVB-T,DVB-T2,DVB-H,DTMB,ATSC,ISDB-T
