Abstract: A portable signal testing system includes a transmitter, a first dynamically tunable receiver, a second dynamically tunable receiver, a first indicator and a second indicator. The transmitter transmits over a wired communications link a first signal having a corresponding first frequency representative of a first frequency range of the wired communications link, and transmits over the wired communications link a second signal having a corresponding second frequency representative of a second frequency range of the wired communications link. Signal losses for the first signal and second signal are measured, and indicators indicate whether the signal losses are acceptable.
