Measure contrast gain reduction at Pin7. Note 4. Set 50kHz generator for 100mVP–P. Adjust R1 for maximum setting. Measure peaking gain reduction at Pin7. Note 5. Adjust R1 for minimum setting. With S2 at switch position 1 and S7 at switch position 3, set 50kHz generator for 2VP–P. Then with S2 at switch position 2, set 1MHz generator for 100mVP–P. Then with S7 at switch position 2, measure downward modulation of the 1MHz signal due to the 50kHz signal. Note 6. Repeat step 5 except that the 50kHz generator must be set at 3VP–P. 14 8 1 7 Pin Connection Diagram Video Input 1 Peaking Input 3 14 N.C.
