IT-19C QAM signal analyzer

IT-19C analyzer was first presented at CSTB exhibition as an updated version of IT-09С. This analyzer is designed for measuring the TV channel parameters with analog and digital modulation. IT-19C has automatic setup parameter detection mode. This device is an indispensable assistant for a technical specialist working in the field, but it is also convenient and easy for stationary use. The analyzer’s interface is designed in such a way that after a few minutes of operation there is a feeling that you have been working with it for many years.
