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 1KW transmitter is installed in one 19inch chassis; it’s suitable for medium
or small TV station.
Features:
● The whole machine is single-channel, image with audio together.
● The redundant configuration design can reduce the rate of inactive to zero.
The exciter redundancy design: the main exciter and its spare exciter can switch
automatically (the spare exciter is optional). When the main exciter broke down,
it can switch to the spare exciter uninterrupted.
The power amplifier redundancy design: multiple amplifiers integrated; the
modules of PA are high-consistency. These two exciters are the spare one with
each other and can exchange easily.
