The Scientel Digital TV transmitter is an 8-VSB professional VHF exciter designed to be used in stand-alone applications or as a driver for higher power amplifier stages. The transmitter is highly reliable, using only passive cooling and including RF output self-monitoring functions. Remote Control/Monitoring can be accessed through a 50-pin CHAMP® connector fully compatible with Davicom MAC units. Two units can be connected together in a master/slave configuration for backup transmitter operation.
