Maximum Line Rate Calculations

The maximum line rate in the camera is limited by either the Camera Link row time or the sensor row

line time. The following calculations are used to determine the maximum line rate.

Variables for calculations:

• User.SOT = 80 | 160 | 320 | 640

• User.CLM = 2(3) | 15(16) | 21

• User.SBH = 1 | 2 | 4

• User.SDH = 1 | 2 | 4

• User.SBV = 1 | 2 | 4

• User.SDV = 1 | 2 | 4

• User.TDI = 0 | 1

• User.STG = 16 | 64 | 128 | 192 | 240 | 256

CL_Taps

• If User.CLM = 2(3) then CL_Taps = 2

• If User.CLM = 15(16) then CL_Taps = 4

• If User.CLM = 21 then CL_Taps = 8

Hor_Bin = User.SBH * User.SDH

CL_Row_Time = ( ( 8192 / Hor_Bin / CL_Taps ) + 8 ) / ( ( User.SOT / CL_Taps ) * 1e6 )

HN_Row_Time = ( 3 + ( ( 36 * User.SBV ) + 545 ) ) / 20e6

HN_Adjust

• If HN_Row_Time > CL_Row_Time then HN_Adjust = 0

• Else HN_Adjust = Ceiling ( ( CL_Row_Time - HN_Row_Time ) * 20e6 )

HN_Rows

• If User.TDI = 1 then HN_Rows = User.SDV

• If User.TDI = 0 then HN_Rows = ( ( User.STG / User.SBV ) + 7 )

HN_Time = ( 3 + ( ( ( 36 * User.SBV ) + 545 + HN_Adjust ) * HN_Rows ) ) / 20e6

Max_Line_Rate = 1 / HN_Time
