According to C-2226 user manual, appendix analog-color: Normal Pen from
Pen 17 = R: 102, G: 102, B: 102
102 (output amplifier)/1024 (total amplifier)=10%, therefore the 10% is the
10 IRE white output pattern.
C. Bright level center block definition:
Pattern set = Pattern name = 1-mosaic,
Color form = norm,
Background color = 0
Foreground color = 25
According to C-2226 user manual, appendix analog-color: Normal Pen from
