Data View Window
This window displays data values associated with the image that is currently being
processed by the built-in analyzer, except in a Dual Link mode where it always shows
data from the serial input.
Data is shown for a specified sample number on the current line, plus samples earlier and
later in that same line. The data may be shown purely as numbers (as shown above) or
together with descriptions in the ‘Extended View’ version of the display (see below). The
total number of pixel pairs displayed is set from the Options menu within the Data View
window (see below). This value can be adjusted between 1 and 512 samples.
The line and sample numbers shown are determined by the position of the main cursor
(crosshair). This position may be changed by clicking in either the Mini-Pic or the
Waveform window, or by using the fine control buttons on the Crosshair toolbar.
The Data View window is scrollable, so you can check video data over a large portion of
a video line without moving the cursor. You can also check data within the blanking area.
Where a Single Link video format is being used, the Data View window displays three
columns of data. In Dual Link mode, the window displays six columns of data. The
column headings displayed reflect the data format selected in the Engineering Settings
control window. Dual Link data can be RGB or YUV.
The contents of the Data View window are colour coded. In all cases, the text remains
white, but the background colour changes to show the nature of the data.
Green indicates pixel is within active video
Blue indicates pixel is within a TRS packet
Purple indicates pixel is within an ANC packet
Light grey indicates pixel is within horizontal blanking
Black indicates pixel is within vertical blanking for field 1
Dark grey indicates pixel is within vertical blanking for field 2
Red indicates a data range error (i.e. video data outside the range that has
been set in the Engineering Settings control window). It is important to
ensure that the data ranges specified in the Engineering Settings
control window reflect the type of data you are expecting.
