Sigma LBA-708, LBA-710, LBA-714PC, LBA-300, LBA-712, LBA-500PC, LBA-700, LBA-400 manual Frame Coordinates

The following describes how to set the pan window to the lower right corner of the detector. In this example the lower right corner of the detector is at (744, 512). The frame data size is 32 X

30.The capture resolution value is 2, so we must multiply the data size by 22=4. Therefore the actual size of the capture window is 128 X 120. To put the capture window in the lower right corner we subtract the capture window size from the lower right limits, 744-128=616 and 512- 120=392.

10.7.3Frame Coordinates

Frame coordinates are used for the frame data stored in the frame buffer. Frame coordinates are dependent only on the frame size. Frame coordinates are always positive with the origin in the upper left corner. Frame coordinates are specified with column and row values. Column values increase to the right and are numbered from 1 to the frame width. Row values increase going down and are numbered from 1 to the frame height.

Frame coordinates are used in the :RCC? and :RCR? commands to specify which column and row to download.

Although :RCC? and :RCR? allow you to download data from the current cursor column and row, there is no way to associate the cursor location in world coordinates (described below) with a particular data frame column or row. Download cursor column and row are intended to be useful only when the cursor is set to follow the centroid, or peak location.
