Composite Display
The instrument provides a composite representation of both SD and HD component signals. To access the composite display, set the color space to composite in Waveform mode or select Composite Graticule in Vector mode.
Data Display (WFM700M Only)
Data Display Colors and Units
The Data Display mode shows the actual SD or HD input data without any interpolation.
Different fields of the data stream are shown in different colors, as shown in Table
Table 3- 2: Data display colors
Color | Use |
|
|
Green | Active video data |
|
|
Gray | Data in horizontal or vertical blanking intervals |
|
|
White | EAV and SAV packets; other reserved values such as the XYZ word |
|
|
Yellow | Data outside the nominal allowed values |

Video / Data Selection The instrument provides two modes for representing signal data: Video and Data.
Video Mode. Shows the data like the video YPbPr display in waveform mode, but without interpolation. The Y, Cb, and Cr traces are offset vertically to separate them, but are aligned temporally. Since Cb and Cr have half the data rate of Y, the samples appear twice as long. Use the Select Channels soft key to turn off individual components of the display.
Data Mode (SD). Shows the data in the same sequence as it occurs in the serial domain. You see a sample of Y, then of Cb, then of Y’ (Y prime), and then of Cr. Then the sequence repeats. The Y sample is the
Data Mode (HD). Splits the serial data into a Y channel and a multiplexed Cb/Cr channel. The intent is to show the data in the same orientation as it occurs in the serial domain, even though it is displayed as 8 or 10 bit values.
