(1)
Adjust the oscilloscope’s amplitude with the UNCAL so that pin 52 and pin 54 waveforms overlap
each other as the bus data is set to the preset value.
(2)
Change the bus data as indicated on the left, and measure values of X and Y shown in the figure
below.
(3)
Find VS according to the equation that VS = (X / Y)×100%.
