Cable TV measurement specifications
Cable TV RF and video measurement
These specifications describe warranted performance of the Agilent CaLan
8591C cable TV analyzer and the CaLan 85721A cable TV measurement
personality from 0° to 50°C after the warmup and calibration described
earlier. Characteristics provide useful, but non-warranted, information
about nominal performance. NTSC-formatted signals only are covered. A
RAM card is needed for the 85721A to store test results. Test data may
also be printed using an HP InkJet or HP LaserJet printer.
