6. Measure the 3·fsc (13.3 MHz) and fsc (4.43 MHz) components in the C-OUT output with no input signal applied.

7. Measure the noise in the C-OUT output with no input signal applied.

Set up the noise meter with a 200-kHz high-pass filter and a 5-MHz low-pass filter.

8. Let V1 be the C-OUT output when 350-mVp-p sine wave signals are input to C-IN1 and C-IN2 with SW3 in the a

position, and V2 be the C-OUT output with SW3 in the b position.
