Notes : 1 1.Voltage gain GV1, 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.

Input threshold voltage Bordering input, character input VTH1, 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 VTH3
Gradually raise TP5 pulse level. TP5 pulse level when a sine wave is no longer output on TP7 is
VTH3.
*7
Sync separation level VSEPA
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 VSEPA.
*8
Schmidt trigger threshold level VTH4H, 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 VVH, VVL
TP3 low level for TTH4H measurement is VVL, and TP3 high level for VTH4L is Vvh.
