NOTE
Option 107 is required for the differential gain/differential phase test.
2. The 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 2-23
shows the FCC composite test signal; Figure 2-24 shows the NTC 7
composite signal.
