speed back to top




shifting takes ~5 µs/column and ~0.7 µs/pixel
readout takes ~3 µs/pixel/readout channel
there are two readout channels, which handle half the data each




example dead-time calculations


full-frame
shift by 1024 1024 x 5 x 10-6 = 0.005 s
shift 10242 pixels 10242 x 0.7 x 10-6/2 = 0.37 s
readout 10242 pixels 10242 x 3 x 10-6/2 = 1.57 s

dead-time = max (0.005, 1.945 - texp) s





100 x 100 window (non drift-mode)
shift by 1024 1024 x 5 x 10-6 = 0.005 s
shift 100 x 1024 pixels 100 x 1024 x 0.7 x 10-6/2 = 0.036 s
readout 1002 pixels 1002 x 3 x 10-6/2 = 0.015 s

dead-time = max (0.005, 0.056 - texp) s
