r&s®nw8500 vhf transmitter family for tv | 概览 -九游官网下载

• multistandard platform for analog, digital and mobile tv
• dvb-t2 capable
• high energy efficiency reduces operating costs
• synergy with all transmitter families of the r&s^®xx8000 generation
• easy switchover from analog to digital tv

the nw8500 is a multistandard platform for analog, digital and mobile tv that can be deployed throughout the world. the transmitters' compact design and high energy efficiency reduce infrastructure and life cycle costs. the modular concept of the r&s^®xx8000 transmitter generation across platforms yields a high degree of synergy with regard to spare parts inventory and operation.

the liquid-cooled transmitter family has been designed for high transmit power in vhf band iii. the r&s^®nx8500 transmitters have an output power of up to 20 kw for analog tv. the coded orthogonal frequency division multiplexing (cofdm) tv standards dvb-t, dvb-t2, isdb-t/isdb-t_b, dtmb as well as the dvb-h and mediaflo^™ mobile tv standards are output with up to 7.8 kw. the maximum output power for the atsc standard and its mobile enhancement atsc mobile dtv is 11.5 kw. the transmitters can be accommodated in one or two 19" racks with a depth of 1200 mm. their small footprint enables them to be flexibly adapted to any site requirements. if requested, they can easily be switched over from analog to digital tv.

¹⁾ other output power ratings on request.
²⁾ before the bandpass filter.

¹⁾ with built-in ac supply overvoltage protection; more stringent requirements must be covered by additional measures installed on-site.

to comply with the applicable standards and limit values for the suppression of out-of-band emissions (and in the case of digital standards, also for maintaining the required shoulder distance), the transmitter may only be operated with suitable filters at the rf output.
