(1)ABCC Window (SE/BSE)

If the results of ABCC are not adequate, you can change the reference brightness and contrast. Adjustable range is -5 to +5. Adjustments can be set independently on the SE and BSE detectors.

(2)FAST SCAN AVERAGING Window

Select number of frames to be averaged for TV1, 2 and Fast1, 2 speeds. Recommended numbers are 4 for TV1 and 8 or 16 for TV2, 2 for Fast1 and 4 for Fast2. The higher the number of frames, the better the attainable image quality. However, the higher number results in longer persistence time. Select an optimal value for the present observed image.

NOTICE: The number of frames to be averaged is set for each screen mode (Full, Small or Dual) independently.
