Setting Camera Gain

DIGITAL GAIN

Sets the camera gain to a factor of 1, 2 or 4.

Type In: Response Explanation

DGN 1 CR-LF Sets the camera gain to unity.

DGN 2 CR-LF Sets the camera gain to times two.

DGN 4 CR-LF Sets the camera gain to times four.

DGN? Queries the current gain setting.

DGN x Indicates that the gain is set to the factor value given.

GAIN BALANCE

The gain of the two output video channels are matched at the factory to minimize

row to row shading. The gain balance command adjusts the gain of one channel

with respect to the other. The adjustment range is from -128 to 127. With the

camera in dual channel readout mode observe a uniform white field with a video

amplitude of 70 % on the video monitor. Change the gain balance until the best

possible image is obtained.

Type In: Response Explanation

GAB xxxx CR-LF Sets the gain of one channel with respect to the other

where xxxx ranges between -128 and 127.

GAB? Queries the current gain setting.

Sample commands with arguments:

GAB 0 Sets the camera gain balance to a value of 0.

GAB -100 Sets the camera gain balance to a value of -100.

GAB 30 Sets the camera gain balance to a value of 30.

STROBE POLARITY

The strobe output on the rear panel of the camera provides a trigger pulse for the

user. The polarity of the strobe signal is set by this command. The strobe output

can drive a 50 ohm load and has a pulse width of 5 microseconds.

Type In: Response Explanation

STP P CR-LF Makes the strobe output pulse polarity positive.

STP N CR-LF Makes the strobe output pulse polarity negative.

STP? Queries the strobe output polarity.
