inequality test

NOTE
Option 107 is required for the Chromalluma delay inequality test.
2. The line number of a test signal is found automatically (if a test signal
exists). The search starts at the default line number (line 18). If a test
signal is not found, the search routine will stop at the first NTC 7 or FCC
composite test signal it finds while counting down from line 22 to line 10.
Figure 2-14 shows the FCC composite test signal; Figure 2-15 shows the
NTC 7 composite test signal.
