MITSUMI Video Amplifier MM1002 Notes : *1 Frequency response fc1, fc2, fc3 For the same conditions as the GU1 measurement, given video output for 0.1MHz as V2, and for 5MHz as V2, FC1 is obtained as follows. The same applies for fC2 and fC3. V2fC1=20LOG dBV1 *2 Character addition ······· input threshold voltage V TH13 For the same conditions as the VCL measurement, adjust VR1 to raise pulse level gradually, and TP7 pulse level when a character signal is output on TP4 is VTH13. Given TP4 level when there is no pulse input as V3, and the level when pulse input exists as V4, C is obtained as follows. V4C=20LOG dBV3 *4 Chroma amp ······ input threshold voltage V TH3 For the same conditions as C measurement, adjust VR2 to raise TP8 level from 0V. The TP8 level when TP4 level changes at pulse input is VTH3. *5 Sync separation ······ sync separation level V SEPA Input a 1VP-P staircase signal (no chroma signal) to SG-1, and gradually shrink the sync signal. TP1 sync level when TP10 horizontal sync signal starts to disappear is VSEPA. *6 Sync separation ······ Pin 7 threshold voltage V TH7H, VTH7L Impress external DC voltage on TP9 and raise gradually from 0V. TP9 level when TP11 level goes from high to low is VTH7H. Lower gradually from 5V. TP9 level when TP11 level goes from low to high is VTH7L. *7 Sync separation ······· horizontal sync output voltage V OH6, VOL6 TP10 high level when a 1VP-P staircase signal (no chroma signal) is input to SG-1 is VOH6, and low level is VOL6. *8 Sync separation ······ vertical sync output voltage V OH8, VOL8 TP10 high level when a 1VP-P staircase signal (no chroma signal) is input to SG-1 is VOH8, and low level is VOL8.
