Abstract
Systems, methods, and non-transitory computer readable media are configured to determine data for subcarriers of a cable modem signal. Values which characterize the cable modem signal can be generated. A plot can then be generated. The plot can depict one or more of the values which characterize the cable modem signal.
Claims20
A computer-implemented method comprising:
- receiving, by a computing system, a modulated signal associated with a cable modem;
- providing, by the computing system, an overview plot of the modulated signal associated with at least one of signal power, modulation error ratio, or noise power, wherein the overview plot includes a plurality of bars corresponding to subcarriers of the modulated signal;
- receiving, by the computing system, a request for a zoom plot associated with the overview plot, wherein the request indicates a selection of a bar from the plurality of bars and a portion of the modulated signal to be provided in the zoom plot, and wherein the portion of the modulated signal to be provided in the zoom plot is associated with a subcarrier corresponding to the selected bar;
- and
- generating, by the computing system, the zoom plot based on the request.
2 more elements
A system comprising:
- at least one processor;
- and
- a memory storing instructions that, when executed by the at least one processor, cause the system to perform a method comprising:
- receiving a modulated signal associated with a cable modem;
- providing an overview plot of the modulated signal associated with at least one of signal power, modulation error ratio, or noise power, wherein the overview plot includes a plurality of bars corresponding to subcarriers of the modulated signal;
- receiving a request for a zoom plot associated with the overview plot, wherein the request indicates a selection of a bar from the plurality of bars and a portion of the modulated signal to be provided in the zoom plot, and wherein the portion of the modulated signal to be provided in the zoom plot is associated with a subcarrier corresponding to the selected bar;
- and
- generating the zoom plot based on the request.
5 more elements
A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system, cause the computing system to perform a method comprising:
- receiving a modulated signal associated with a cable modem;
- providing an overview plot of the modulated signal associated with at least one of signal power, modulation error ratio, or noise power, wherein the overview plot includes a plurality of bars corresponding to subcarriers of the modulated signal;
- receiving a request for a zoom plot associated with the overview plot, wherein the request indicates a selection of a bar from the plurality of bars and a portion of the modulated signal to be provided in the zoom plot, and wherein the portion of the modulated signal to be provided in the zoom plot is associated with a subcarrier corresponding to the selected bar;
- and
- generating the zoom plot based on the request.
