Abstract: Systems and methods e to automatically analyze and display results of tests of a link include obtaining data from one or more tests of a link, wherein the data includes samples for Antenna Carriers (AxC) for one or more AxCs auto-detected on the link; processing the data to detect peaks on any of the auto-detected AxCs on the link; performing an analysis of any detected peaks to identify any issues on the link; and causing display of a user interface that includes a reporting of any identified issues with the user interface including a display of the identified issues and a spectrum graph.

Abstract: In order to improve the analysis of the RF interferences, there is provided a peak selection assistance method for finding a local peak in an RF spectrum trace. The method provides a window on the spectrum trace display, which can be configured and/or moved by a user from user interaction on said user interface. When the window is defined, the method finds the highest peak within the window and optionally adds a marker on it. The method therefore snaps to the highest peak within the window. This improves the way of precisely detecting the maximum amplitude and the center frequency for any local peak on the spectrum.

Abstract: A Radio Frequency (RF) spectrum analyzer includes an RF front end including a single antenna configured to monitor a wireless network that includes Time Division Duplexing (TDD); and circuitry connected to the RF front end and configured to operate and monitor the wireless network both in a spectrum analyzer mode and a signal analyzer mode, utilize the signal analyzer mode to extract synchronization information from the monitored wireless network, derive a start of frame of a radio frame from said the synchronization information; and utilize the synchronization information to identify an acquisition window to synchronize a gate in the spectrum analyzer mode.

Abstract: A test system and a related method, the system comprising a test processing agent and local test device(s). The test processing agent processes test measurements related to a network-under-test into test results. The test processing agent is decoupled from the network-under-test, e.g., by being reachable through a network communication link distinct from the network-under-test. The local test device comprises a firmware module and a network interface (NI) module. The firmware module depends on external instructions for initiating a test sequence on the network-under-test. The NI module comprises at least one physical port connectable to the network-under-test. The physical port is used for initiating the test sequence. The test processing agent receives the test measurements following the initiation of the test sequence by the local test device and allows access to the test results.
