Desired Integration Time Uncertainty ± 15 µs Window 3.9 Optimizing Offset Performance Set the analog offset of the camera using the command: Syntax: Syntax Elements: sao t i t i Tap value. Use 0 for all taps or 1 to 2 for individual tap selection. Offset value. Allowable range is from 0 to 1023. 3.10 Setting Gains Notes: The offset increases with higher values. The resulting analog offset value depends on other camera parameters such as temperature, frame rate, and gain but will fall somewhere between 1 and 10 DN. Example: sao 0 500 To set the analog gain portion of the camera, use the command: Syntax: Syntax Elements: sg t f t f Tap value. Use 0 for all taps or 1 to 2 for individual tap selection. Example: sg 0 2.5 Gain setting. Allowable range is 0 to 15dB. For nominal gain, set to 0. DALSA 03-32-10157-02
DS-24-02M30 and DS-25-02M30 User’s Manual 27 3.11 Increasing Sensitivity with Binning (DS-24- 02M30 Only) Binning increases the camera’s light sensitivity by decreasing horizontal and vertical resolution—the charge collected by adjacent pixels is added together. Figure 12: 2x2 Binning More charge = brighter pixel q1 q3 2 q2 q4 Charge in 4 adjacent pixels q1 + q2 + q3 + q4 1 Charge binned: 1 pixel output a Normal image a Binned image To set the binning value, use the command: Syntax: sbm i i Syntax Elements: i Horizontal binning value. Must be identical to the vertical binning value. i Vertical binning value. Must be identical to the horizontal binning value. Notes: Available values are 1x1 (factory setting), 2x2, or 4x4. Example: sbm 2 2 To return to 1x1 mode (binning disabled), use the command sbm 1 1. Binning is recommended for the monochrome (DS-24-02M30) 2M30 only. Using binning with the color (DS-25-02M30) 2M30 will cause invalid pixel summations.
