    • A channel plan with a corresponding test plan are implemented in connection with a plurality of nodes that communicate signals. The channel plan has one or more predefined specifications for each of one or more signal channels on each of the nodes. The channel plan may comprise a specification of the following, for example, for each of the channels: a label describing use of the corresponding channel, a center frequency, a bandwidth, a power level, information regarding the carrier roll-off, a default status indicator identifying whether the corresponding channel is currently allocated or reserved for future use, one or more default threshold levels for various tests, and an alternate center frequency that may be utilized by the corresponding channel. The channel plan enables a monitoring system to, among other things, conduct automatic periodic test plans, comprising tests, on the nodes, based upon the predefined data specified in the channel plan. Each test plan prescribes measurement of at least one signal parameter, pertaining to one or more nodes as a whole and/or to one or more channels contained within the nodes. The monitoring system includes a spectrum analyzer, a switch enabling the spectrum analyzer to interface with the nodes, and a controller controlling the switch and the spectrum analyzer. The controller is configured to enable creation of and display the channel plan and test plan, based upon user inputs. Notably, the test plan may include alarm limits that are triggered and tracked when a signal parameter of a node or channel exceeds an alarm limit.
    • 与传送信号的多个节点相关联地实现具有相应测试计划的信道计划。 信道方案具有针对每个节点上的一个或多个信号信道中的每一个的一个或多个预定义规范。 信道方案可以包括以下的规范,例如对于每个信道:描述对应信道的使用的标签,中心频率,带宽,功率电平,关于载波滚降的信息,默认的 状态指示符,用于识别对应的信道当前是分配还是保留用于将来使用,用于各种测试的一个或多个默认阈值级别,以及相应信道可以利用的替代中心频率。 通道计划使监控系统能够根据通道计划中指定的预定义数据,在节点上执行包括测试在内的自动周期测试计划。 每个测试计划规定了至少一个信号参数的测量,该信号参数关于一个或多个节点作为整体和/或包含在节点内的一个或多个信道。 监控系统包括频谱分析仪,能够使频谱分析仪与节点进行接口的开关,以及控制开关和频谱分析仪的控制器。 控制器被配置为基于用户输入创建和显示通道计划和测试计划。 值得注意的是,当节点或通道的信号参数超过报警限制时,测试计划可能包括触发和跟踪的报警限制。
