Features132 Basler sprint Mono Cameras6.4 Test ImagesThe test image mode is used to check the camera’s basic functionality and its ability to transmit animage via the video data cables. Test images are especially useful for service purposes and forfailure diagnostics. In test mode, the image is generated with a software program and the camera’sdigital devices and does not use the optics, imaging sensor, or ADCs. Four test images areavailable.Guidelines When Using Test Images When using a test image, take the following guidelines into account:If the camera is set for an exposure mode that uses an ExSync signal, the ExSync signal mustbe present and must toggle in order to output a line on the test image. Multiple transitions of theExSync signal will produce a two dimensional image as shown in Figure 44 on page 133 orFigure 46 on page 134. If the camera is set for free run, each cycle of the camera’s internal control signal will triggerthe output of a line on the test image. The length of the exposure time has no effect on test images.Enabling Test ImagesYou can enable a test image with the Camera Configuration Tool Plus (CCT+) or by using binarywrite commands from within your own application to set the camera’s control and status registers(CSRs).With the CCT+With the CCT+ (see Section 7.1 on page 156), you use the Test Image Mode parameter in theOutput Mode parameters group to enable a test image.By Setting CSRsYou enable a test image by writing the appropriate value to the Mode field of the Test Image ModeCSR (see page 179).See Section 7.2.2 on page 164 for an explanation of CSRs and Section 7.3.1 on page 197 for anexplanation of using read/write commands.
