QAM Signal Analyzer 1720/1730

1. 1720QAM & 1730QAM Signal Analyzer?

The very excellent signal analyzers of choice for field testing of QAM digital signals on your CABLE-TV SYSTEM.
They demodulate and accurately measure the QAM signals carried through the cable system.
They provide the measurement power the field technicians need for the latest 64-256QAM digital technologies and are very simple to use, measuring SNR(MER), EVM, Pre-BER, Post-BER, Constellation Diagram.

  • 1720 QAM Frequency range : 5MHz ~ 870MHz
  • 1730 QAM Frequency range : 5MHz ~ 1000MHz(1GHz)
