R&S®NM8200 VHF Transmitter Family
Air-cooled medium-power transmitters for analog TV
Transmitter rack with integrated cooling
A 19“ rack (depth 800 mm) is used for all power classes. One rack accommodates up to six amplifier modules. The rack contains two built-in fans that operate in active standby.
Various air ducting configurations can be implemented, with cooling air intake from the top, bottom or rear of the transmitter rack, and exhaust air discharge toward the top or bottom. Each amplifier module contains an optimized, highly efficient heat sink. This in conjunction with the elaborate cooling concept ensures effective cooling with only small amounts of air. This in turn considerably reduces the cooling system‘s power consumption and noise generation.
An innovative, nearly wireless power distribution system eliminates wiring errors during assembly.
A channel filter integrated in the transmitter (for analog operation), a frequencyresponse-compensated directional coupler and built-in lightning protection round out the R&S® NH/NV8200 family of transmitters.
