The page displayed depends on a combination of the On Screen
Display (osd) value and the On Screen Display Page (osp) value.
If showing the Original OSD page the spectrum plot will correspond to
the On Screen Display (osd) value.
If showing the new Engineering Data page, the spectrum plots will
correspond to:
A and B if On Screen Display (osd) value = 1 or 2
C and D if On Screen Display (osd) value = 3 or 4
C and D will only be displayed if available.
