Installation & Operation Manual GM-TTTPage 433.7 TESTThis display permits to indicate some measurement results:1 Time difference between the internal and external sync signals. The digits 8 and 7specify the milliseconds, the example below indicates the value 39.999812 ms. It isaccurate to ±125ns.Digit 8 Digit 7 Digit 6 Digit 5 Digit 4 Digit 3 Digit 2 Digit 1= 39.999812 ms2 Period of the external sync signal: Video or Black-Burst, respectively, or LTC signal. Thedigits 8 and 7 indicate the milliseconds, the example below indicates the value39.999812 ms. It is accurate to ±125ns.Digit 8 Digit 7 Digit 6 Digit 5 Digit 4 Digit 3 Digit 2 Digit 1= 39.999937 ms3 Time difference between the seconds pulse and the V1sync signal. The digits 8 and 7specify the milliseconds, the example below indicates the value 39.999812 ms. It isaccurate to ±125ns.The digit 1 specifies the colour sequence of the video signal at the moment of theseconds pulse at seconds 00, 04, 08 ... by using an index. The index = 0 specifies thefields 1/2, 1 = 3/4, 2 = 5/6, 3 = 7/8. If the time code is generated with colour framingin the time operating mode, the time information in the time code may be corrected bysome frames compared to the reference time, depending on the colour sequence of thevideo signal. In the 625/50 system, no correction is performed, if digit 1 indicates 3.This also refers to the 525/60 system, when digit 1 indicates 0. A diagram in the chapterentitled “Real Time Coupling of Time Code and Video“ further explains this situation.If no colour framing is selected, digit 1 remains empty.Digit 8 Digit 7 Digit 6 Digit 5 Digit 4 Digit 3 Digit 2 Digit 1= 15.39953 ms ColourLockSequence
