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 3-2. Use the Readout Format soft key to view the data in Hex, Decimal, or Binary units.

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

 

 

Red

Data with illegal 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 co-sited sample, and the Y’ sample is the isolated luma sample.

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.
