  • RF spectrum analyzer for TDD transmission that maintains synchronization between UL and DL with a single antenna
    Patent number: 12520253
    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.
    Type: Grant

  • Automated analysis of RF spectrum
    Patent number: 10735109
    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.
