Table 4: Waveform Sweep (Horizontal) Deflection
Characteristic Performance requirement Reference information
Accuracy
± 0.5%, all rates Line sweeps for 1080P 60/59/50 dual link
formats are shown with image scanning time
scale. In these formats, each link operates
at
1
/
2
the image scanning rate, so link time
scale is twice the indicated time per division.
Sweep
Linearity
0.2% of time displayed on screen
