Patent ID: 8416922

Claim:
A signal testing apparatus 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 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 acceptable; a second 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 acceptable; a first indicator that provides indication of whether the measured signal loss for the first signal is acceptable; and a second indicator that provides indication of whether the measured signal loss for the second signal is acceptable.
