Characteristic Performance requirement Reference information
Timing Display Zero Definition For vertical timing, conforms to SMPTE
168-2002
For horizontal timing, zero delay analog
signals have coincident syncs. For digital
signals, timing is such that if converted to
analog by a WFM601A, then the r esultant
analog signal is conincident with the
reference
Timing zero is equivalent to nominal zero
delay on TG700. Also agrees with signal that
shows minimal shift on the waveform display
when going from internal to external
Vertical timing, according to SMPTE 168,
specifies that the lines with the start of the
broad pulses are aligned
Operation with input and reference
being different formats
Compatible with any combination of frame
abd field rates. (See Table 45.)(See
Table 46.)(See Table 47.)l. In cases where
there are multiple ways to interpret the phase
relationship, multiple indicators of the phase
will be shown. The numeric display will
follow the smallest phase offset
Link B to Link A
Display of dual link timing skew. Uncertainty
of ± 1.5 clocks or 20 ns.
Input Timing Reference to Other
Input
For Simultaneous inputs, allows selection of
other channel as reference.

Al
lows viewing picture in all formats
In SD formats, full screen picture occupies
the central portion of the XGA raster area.
Fo
r tile mode, the image is downsampled to
fit the 512 x 350 size
In HD formats, picture is downsampled to fit
i
n 1024 x 768 size (512 x 350 in 4-tile mode).
In 1080P 60/59/50 dual link formats, picture
is formed by averaging two l ines, one from
e
ach link, then downsampling as required for
display
In Low Frame Rate formats, frames are
repeated as needed to achieve XGA frame
rate; similar to 3:2 pulldown on some frame
rates
