  ¡á DVB-T SIGNAL ANALYZER 1730OFDM

  ¡á MAIN FEATURES

  • 1730OFDM are the best choice for the field technicians to measure digital terrestrial TV(DVB-T standard).
  • Frequency Range : 5MHz ~ 1000MHz(1GHz)
  • They demodulate and accurately measure the COFDM signals carried through the terrestrial TV system.
  • They are very simple and convenient to use and measure SNR(MER), EVM, Pre-BER, Post-BER, Constellation Diagram for the digital TV channels.
  • Portable type, Weight less than 1Kg, Computer interface.
