The filters available are dependent upon the input format. The filters available are:
• Flat: No filtering.
• Low Pass: Selects the Low Pass filter.
• Chroma: Selects the Chroma filter.
• F/LP: Selects Flat and Low Pass filtering
• R-Y: Selects the R-Y filter (selection available with TVM-VTM-ACV-2 option

• Bowtie: The bowtie filter is used to check the timing relationships between the
digital components. A bowtie test signal is required.
Parade and Overlay Selections
Multiple inputs can be displayed in a single pane.
• When PARADE is selected, the components of the same input are shown next to
one another (i.e. Inputs Y, then CB, then CR in a YCBCR signal).
• When OVERLAY is selected for a single input, the components of the input signal
are displayed over each other (i.e. R over G over B in an RGB signal). When
OVERLAY is selected for A & B, like components of each input are over each
other (i.e. R over R, G over G, and B over B). A & B cannot be displayed in parade
mode.
