The Coax Clarifier determines individual run quality as well as to determine the ability of the overall system's capability to deliver good quality video at both standard and high definition levels. With an easy-to-read large backlit LCD, the Coax Clarifier shows loss levels on each coax cable run and displays a bar graph of quality for each. Detecting and testing splitters for quality, shorts/opens, etc., is also done on each test. Finally, the Coax Clarifier uses inexpensive wiremap remotes that allow the technician to singlehandedly map an entire system easily and quickly.
