Note 1 Set 50kHz generator for 200mV
rms
. Adjust R1 Peaking control for minimum setting, measure
wide−band gain at terminal 7.
Note 2 Set 50kHz generator for 200mV
rms
. Adjust R1 for minimum setting, measure contrast gain
reduction at terminal 7.
Note 3 Set 50kHz generator for 200mV
rms
. Adjust R1 for minimum setting, measure peaking gain
reduction at terminal 7.
Note 4 Adjust R1 for minimum setting. With S2 at switch position 1 and S7 at switch position 3, set
50kHz generator for 3.8V
p−p
. Then with S2, set 1MHz generator for 200mV
rms
. Then with
S7 at switch position 2, measure downward modulation of the 1MHz signal due to the 50kHz
signal.
