Test Method
Apply a pulse to pin 68 as shown in Figure A.
Monitor # 12 output waveform. Plot # 12 output amplitude when changing # 68 input signal
amplitude from 0 to 120 IRE (0.857 Vp-p) (See Figure B below).
Set subaddress (19) data to (80).
Monitor # 12 output waveform. Plot # 12 output amplitude when changing # 68 input signal
amplitude from 0 to 120 IRE (0.857 Vp-p). Then, compare to the plot in the step 2, calculate
a point where a gradient changes (WPL1).
Repeat the step 4 above by changing subaddress (19) data to (83) and (86). Calculate
points where gradients change (WPL2, WPL3).
