Maximum pixel rate of board, DT3154
What is the maximum pixel
rate of the DT 3154 board?
Answer: (That is, what is the maximum frequency at which the board can perform A/D conversions?) The information is in the website documentation (DT3154 User Manual) and in our 2000 Product Handbook.
For the DT3154 board, the pixel
rate is fixed.
Video @ 50 Hz: (25 frames/sec) * (442368 pixels/frame
) ~ 11,000,000 pixels/sec
Video @ 60 Hz: (30 frames/sec) * (307200 pixels/frame
) ~ 9,200,000 pixels/sec
These are the maximum rates. Depending on what you are trying to do, i.e. performing a passthru operation or saving to memory
/disk, the transfer rate can be slower. FYI: The internal clock
frequency (fixed) is faster to allow for other information.
@ 50 Hz: 15,000,000
@ 60 Hz: 12,500,000
