NOTES:
3. Determine VCONT-LOW for 40 dB attenuation of output. Reference to AV(max).
4. Measure gain difference between any two amplifiers, VI(PP) = 1 V.
5. Adjust input frequency from 10 kHz (AV(max) reference 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.
