    RDL-100 Video Signal Generator System Control Software V1.0 Operating Instructions.

    Write the purpose

The purpose of this document is to introduce the operating instructions and operation steps of the RDL-100 video signal generator system control software V1.0 for easy user use.

The RDL-100 video signal generator system control software V1.0 is opened displays the main control and display interface in Figure 1, including 10 controls of Time, Pattern, Pixel, Audio Freq, Audio Level, Preview, Play, Signal, Minimized, and Closed.

  • The Preview control

The control is shown in FIG. 8 to preview the selected video signal for the user reference.

graph 8

  • Play control

The control is used in FIG. 9 to play and stop playing the video signal. When the button is playing the video signal, stop playing the video signal when the button is extinguished. When playing the video signal, the Time, Pattern, Pixel, Audio Freq and Audio Level controls are prohibited, and the interface is shown in FIG. 10.

Three Vertical Bar Signal IEC62368 Three Vertical Bar Signal

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

3.2.1 .3 Three vertical bar signalE.L. IEC 60238 A1 2017 2018-04-03.doc
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.
