7.2.4

LINE IT

integration time

This command is used to control the integration time (effective exposure time) for each line.

The timing can be specified either as an absolute time in microseconds, or as percentage of the

line period. The integration time given as percentage of the line interval is recalculated

automatically when the line rate changes. The integration time set in absolute units remains

constant, unless the line rate setting forces the camera to shorten it.

Command

Description

LINE IT ?

Returns the command syntax.

LINE IT

Returns the present Line Integration setting.

LINE IT <time>

Sets the integration time to <time> in microseconds, where <time> is a

numerical value between 2.00 – 99998.50 with 0, 1 or 2 decimal places.

LINE IT <time>%

Sets the integration time to <time> per cent of the line interval, where

<time> is a numerical value between 0.10 % to 100.00 % (default) with

0, 1 or 2 decimal places.

7.2.5

GAIN

- signal gain

The gain control can be used to scale the camera response up or down. In addition to the gain

control the Sensor responsivity can be selected to be Dynamic or Responsive giving a factor of 6

in responsivity due to the difference in quantum well size.

Please note that it is not practical to repeatedly swap the well. Instead, it is better to select it

first and then use only the GAIN command as far as possible.

Command

Description

GAIN ?

Returns the command syntax.

GAIN

Returns the present Gain setting.

GAIN <value>

Sets the Gain to <value>, where <value> is any number between 0.1

and 32 with up to three decimals. The default setting is 1.000

7.2.6

OFFSET

- output offset

The value given by this command is directly added to or subtracted from all the pixel values

prior to applying the GAIN.

Command

Description

OFFSET ?

Returns the command syntax.

OFFSET

Returns the present Offset setting.

OFFSET <offset>

Changes the signal level prior to the GAIN stage.

Offset is always given as a 12-bit number. Offset changes in any 10

bit scale need to be multiplied by a factor of 4 to get the correct

value for this command. Respectively, 8 bit offsets must be

multiplied by 16. Default value is zero.

<offset> is a positive or negative integer within a range of -1023 to 1023. This equals ± 25 % of
