Patent ID: 8625745

Claim:
A portable signal testing system for testing signals, comprising: a transmitter that 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 that 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; a first dynamically tunable receiver that receives the first signal having the corresponding first frequency representative of the first frequency range of the wired communications link, and measures a signal loss for the first signal to determine whether the measured signal loss for the first signal is higher than a predetermined threshold; a second dynamically tunable receiver that receives the second signal having the corresponding second frequency representative of the second frequency range of the wired communications link, and measures a signal loss for the second signal to determine whether the measured signal loss for the second signal is higher than a predetermined threshold; a first indicator that provides indication of whether the measured signal loss for the first signal is higher than a predetermined threshold; and a second indicator that provides indication of whether the measured signal loss for the second signal is higher than a predetermined threshold.
