  • TEST DEVICE FOR INTERFERENCE TESTING OF TIME DOMAIN DUPLEXING SIGNALS
    Publication number: 20230133796
    Abstract: A test device is operable to detect interference in a time division duplex (TDD) cellular network. The test device can automatically detect a TDD frame structure of RF signals received over the air Eagle Eye from a cell site. The test device determines a transition period between uplink (UL) and downlink (DL) transmissions in which no UL and DL signals are being transmitted based on the TDD frame structure. An interference signal is detected during the transition period, and the test device can generate a display of the spectrum during the transition period that includes the interference signal.
