1. A system, comprising:

  • a processor; and

    a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

    cycling a test signal at a defined period, wherein the test signal is in a first band and is transmitted by a transmitter;

    receiving a transmission in a second band by a receiver; and

    determining that an intermodulation product from the test signal is present in the transmission based on matching a period of a cyclical noise measurement of the transmission to the defined period and based on a noise amplitude harmonic identified at a defined frequency gap from the second band.
