PCU-1500 / PCN-1800

PCU-1500 / PCN-1800

NEC transmitters are renowned throughout the broadcast community for their superior reliability and minimal maintenance
requirements. The new series are the outcome of NEC’s vast experience in providing thousands of transmitters around the
world, applying our sophisticated expertise in product design to set a new standard in ultra-compact UHF (PCU-1500) and VHF (PCN-1800) analog TV transmitters.

Features

  • Easy conversion to digital TX
    Can be converted to digital and utilized as auxiliary transmitters or main transmitters in order to increase the number of MUXs (multiplexers) and utilize resources more effectively. A new digitalized exciter is introduced to enables easy conversion from analog to digital through the replacement of software.
  • All-band solution
    Broadcasters are required to employ broadband-compatible transmitter units in situations that require channel change for common spare units or digital conversion. NEC’s PCU-1500/ PCN-1800 series provides an optimum solution for this requirement. Its exciter features direct modulation and a synthesizer, enabling the transmitter to be used for any UHF/ VHF channel, simply by changing the frequency setting, and eliminating the need for BPF (Band Pass Filter) adjustment at the exciter stage. Its power amplifier (PA) incorporates a frequency table that automatically adjusts the gain and phase, providing an all-band solution and streamlining frequency adjustment.
  • Superior maintenance function
    The automatic correction function in the exciter’s compensation circuit makes it extremely easy to perform characteristics adjustment as an automatic compensation, without having to use a demodulator. Equipped with color LCD panel and warning
    indication facilitates.
  • User-friendly monitoring
    The TX control unit features a built-in web server and SNMP. Monitoring and control are accessible from PC with web browser.
  • Sophisticated hybrid liquid cooling
    Simple but highly efficient cooling method that incorporates an automatic air-purge function and ensures easy water feeding.
