1.2 GHz Frequency Range TV QAM Analyzer
Features:●5 MHz to 1052 MHz range (analog signals)  |
The DS2460Q is a multi-functional instrument that supports digital QAM and analog signals in CATV networks It is the ideal tool for initial network installations, service, and troubleshooting tasks The ruggedized design includes an outer chassis protector, while the icon-based GUI features programmable preset pass/ fail limits. The easy-flowing menus are designed for increased efficiency and productivity for all levels of technicians.
MER, Pre & Post BER measurements, and statistics features allow quick verification of loose connections, generally related to pixelated pictures or slow DS internet data flow. The digital measurement functions also help identify mismatches caused by open coaxial lines or impedance mismatch.
Other features - including return path & forward spectrum scan, 12 favorite tilt frequencies, AC line voltage test, HUM and DC voltage measurements, combined with complete data logging and management software - make this unit a versatile tool for cable installations.
