摘要： A network testing device may be linked to a dedicated remote server e.g. a cloud-based server having a unique, pre-determined address. The testing device may be configured to cease operating, become locked or limited in testing functionality after a number of startup cycles, days of use, a certain date, etc. Once the testing device is locked, the testing device may be re-activated only by establishing a connection to the server. A database of network testing devices currently in use may be provided. Once a testing device is lost or stolen, the database may be remotely updated to prevent reactivation of that testing device, so as to render the lost or stolen testing device useless for an unauthorized operator of the testing device.

摘要翻译： 网络测试设备可以链接到专用远程服务器，例如 一个基于can的服务器具有唯一的预定地址。 测试设备可以被配置为在多个启动周期，使用日期，某一日期等之后停止操作，变得锁定或测试功能受限。一旦测试设备被锁定，测试设备可以仅被重新激活 通过建立与服务器的连接。 可以提供当前使用的网络测试装置的数据库。 一旦测试设备丢失或被盗，数据库可能会被远程更新，以防止该测试设备的重新启动，从而使测试设备的未经授权的操作员无法使用丢失或被盗的测试设备。

摘要： A signal leakage in a cable network may be detected by using a test device to obtain a spectrum of an electromagnetic wave propagating in vicinity of the cable network, and automatically detecting QAM channels in the obtained spectrum by detecting characteristic spectral roll-offs at boundary frequencies between QAM channels of the cable network. A test device may be used to determine which QAM channels are currently active on the cable network, thereby facilitating automatic QAM signal leakage detection.
