MITSUMI S Video Amplifier MM1024 Notes : *1 1.Voltage gain G V1, GV2, GV3 Given SG-1 input as V1 and TP11 output signal as V2, GV1 is obtained as follows. The same applies for GV2 and GV3. V2GV1=20LOG [dB]V1 2.Frequency response fC1, fC2, fC3 For the same conditions as the GV1 measurement, given TP11 output for 0.1MHz as V3, and for 5MHz as V1, Fc1 is obtained as follows. The same applies for fc2 and fc3. V4fc1=20LOG [dB]V3 *2 Crosstalk Y IN COUT CT1 Given TP14 input signal as V5 and TP7 output signal as V6, CT1 is obtained as follows. V6CT1=20LOG [dB]V5 *3 Crosstalk P B, PB YOUT CT2, CT3 Give TP2 and TP4 input signals as V7, and TP11 output signal as V8, CT2 and CT3 are obtained as follows. V8CT2=20LOG [dB]V7 1.When C is input to compare between YIN COUT and CIN YOUT, subtract the 4dB amp portion from crosstalk. *4 Crosstalk PB C OUT CT4 Given TP4 input signal as V9 and TP7 output signal as V10, CT4 is obtained as follows. V10CT4=20LOG [dB]V9 *5 Input threshold voltage Bordering input, character input V TH1, VTH2 For the same conditions as VEDY and VCHY measurement, raise TP13 and TP12 pulse levels gradually. TP13 and TP12 pulse levels when bordering signal and character signal appear on TP11 are, respectively, VTH1 and VTH2. *6 Input threshold voltage Chroma mute input V TH3 Gradually raise TP5 pulse level. TP5 pulse level when a sine wave is no longer output on TP7 is VTH3. *7 Sync separation level V SEPA Gradually reduce SG-1 SYNC level from maximum to minimum. Measure the SYNC signal level at TP14 when a sync separation signal is no longer output on TP15 to obtain V SEPA. *8 Schmidt trigger threshold level V TH4H, VTH4L Impress external DC voltage on TP1 and gradually raise from 0V. TP1 level when TP3 level goes from high to low is VTH4H. Gradually lower from 5V. TP1 level when TP3 level goes from low to high is VTH4L. *9 Vertical sync output voltage V VH, VVL TP3 low level for TTH4H measurement is VVL, and TP3 high level for VTH4L is Vvh.
