The VM Series system performs the color bars measurements by first identifying the relative amplitudes of each of the three
channels. Eight amplitude measurements are made on each channel, giving a total of 24 measurements in less than half a
second; the following steps show the typical measurement results performed on a 1024x768 signal. The amplitude level of
each of the bar levels is measured relative to the back porch. Amplitudes are calculated using waveform averaged values
within each identified bar. Therefore, it is important to ensure that the full video is displayed in the capture window of the
instrument if manual setup has been performed on the unit.
