VSB/QAM SIGNAL ANALYZER 1720/1730?

The optimal signal analyzers to test and measure both digital TV signals(8/16VSB) and digital CATV signals(64/256QAM).
Especially, these models give users the capacity to measure SNR(MER), EVM, Pre-BER, Post-BER, Constellation Diagram very easily and correctly, which are very important measurement factors for the digital signal quality.
