Abstract
The present technology provides solutions that enable accurate measuring of frequency response on a network (e.g., cable network, fiber optic network) through frequency sweep testing. In various embodiments, the present technology provides a remote transmitter test unit that can be physically deployed at various points in a network. The present technology provides for on demand sweep testing. A remote transmitter test unit or headend test unit can periodically transmit a query message and, based on a response to the query message, can initiate a sweep test. The present technology provides for automatic generation of a sweep profile for a sweep test. Based on an analysis of a frequency spectrum on a network, the sweep profile provides parameters for conducting a sweep test. The present technology provides for Orthogonal Frequency-Division Multiplexing (OFDM) table generation and OFDM sweep testing.
