Note 2. Set 50kHz generator for 100mVPP Adjust R1 Peaking Control for minimum setting. Measure wideband gain at Pin7. Note 3. Set 50kHz generator for 100mVPP. Adjust R1 for minimum setting. Measure contrast gain reduction at Pin7. Note 4. Set 50kHz generator for 100mVPP. 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 2VPP. Then with S2 at switch position 2, set 1MHz generator for 100mVPP. 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 3VPP.
