Syncro:
When operating in this mode, the Shutter Speed values may be proportionately re-
duced or extended to tune exposure time to a precise value. Range 10 – 90. Default 50.
E.g. Setting Syncro to 53 with a 1/60
th
sec shutter is equal to 1/56.6 sec exposure time.
Phase:
provides a delay relative to the start of the frame for the exposure time. Phase may be
adjusted over the range - 45 to + 45 degrees. Default value is 0.
Note: To Convert Shutter Speed to Angle Equivalent
Equivalent Degrees = (Shutter Speed x Frame Rate x 360)
E.g. = (1/48 x 24 x 360) = (8640 / 48) = 180

Note: To Convert an Angle to an Equivalent Shutter Speed
Equivalent Shutter = 1 / ( Frame Rate x 360 / Angle )
E.g. = 1/ (24 x 360 / 180) = 1/ (8640 / 180) = 1 / 48
