3.7.2 Setting Line Rate
To set the line rate, use the command:
Syntax:
ssf f
Syntax Elements:
i
Desired line rate in Hz. Allowable values are 1000 to 51540 if
vertical binning is set to 1 (sbv 1), or 1000 to 48850 if vertical
binning is set to 2 (sbv 2).
Notes:
• To read the current line frequency, use the command gcp.
• If you enter an invalid line rate frequency, an error message is
returned.

3.8 Increasing Sensitivity with Binning
Binning increases the camera’s light sensitivity by decreasing horizontal and/or vertical
resolution—the charge collected by adjacent pixels is added together.
Setting Horizontal Binning
To set the horizontal binning value, use the command:
Syntax:
sbh i
Syntax Elements:
i
Horizontal binning value. Available values are 1 (factory
setting, no binning) or 2.
Notes:
• If you are using binning (sbv 2 or sbh 2), the min, max, and
mean statistics generated by the gl or gla command are for
every second pixel only.
Example:
sbh 2
