<1>The multi tone spec is the spec which defines system performance. The two tone spec is available because it may not be possible

to create an adequate multi-tone signal with the test hardware.

<2>Two tone A distortion is measured with two sine waves with each sine wave at an amplitude of 1/2 full scale. Tone one is at

f1=500kHz and tone two is at f2=300kHz.

<3>Two tone B distortion is measured with two sine waves with each sine wave at an amplitude of 1/2 full scale. Tone one is at

f1=500kHz and tone two is at f2=450kHz.
