1. 1720T & 1730T Signal Analyzer?

The best choice for the field technicians to measure digital terrestrial TV(DVB-T standard).
They demodulate and accurately measure the OFDM signals carried through the terrestrial TV system.
They are very simple and convenient to use and measure SNR, MER, EVM, BER(PRE-BER, POST-BER), CONSTELLATION DIAGRAM for the digital TV channels.
