WFM700 Series Waveform Monitors User Manual

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)
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
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). S hows 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.
