Three vertical bar signal’ shall be used as defined in 3.2.1.3 of IEC 60107-1:1997

3.2.1 .3 Three vertical bar signal
The three vertical bar signal produces three equidistant vertical white bars on a black background. The width of each bar is 1 /6 times the nominal horizontal width ( W ) of the picture.
A line-time waveform of the signal is shown in figure 9. This signal has an APL of 50 % and includes the reference white level. It is suitable for setting the output signal level and the luminance level of white For the SECAM measurements, the subcarrier with the frequency and amplitude corresponding to black and white is superimposed on the signal.
The same bar width can be applied for the wide aspect ratio picture.
