NOTES:

3. Determine VCONTRASTLOW for – 40 dB attenuation of output. Reference to AV maximum.

4. Measure gain difference between any two amplifiers, VI(PP) = 1 V.

5. Adjust input frequency from 10 kHz (AV maximum ref level) to the – 3 dB corner frequency (f – 3 dB). VI(PP) = 700 mV.

6. VI(PP) = 700 mV at f = 10 kHz to any amplifier. Measure output levels of the other two undriven amplifiers relative to driven amplifier.

7. A special text fixture without a socket and a double-sided full-ground-plane PC board are required.
