1)
Set the BUS control data to the preset value.
2)
Input a 2T pulse (STD) signal to TP78, turn the Y mute off (1), turn the video mute off (0), set unicolor to maximum
(1111111), and set SHR tracking to SRT-gain low (11).
3)
Set the sharpness control to the center (1000000), set the aperture compensator peak frequency to 4.2M (001),
connect TP11 and TP15b, and observe TP15a.
4)
Measure TSL1 as in the diagram below.
5)
Set SHR tracking to SRT-gain high (00) and measure TSL2.
6)
Next, set the aperture compensator peak frequency to 7.7M (111) and measure TSH1 and TSH2 as above.
7)
Calculate the following formula.
TSRTL = TSL1 TSL2
TSRTH = TSH1 TSH2
