Unformatted text preview: Scan and Motor Dialog Box The Scan and Motor dialog box controls the X / Y scan. Open the dialog box by clicking the Imaging toolbar button . The Servo and Realtime Images dialog boxes will also open. Scan tab Advanced tab Motor Tab Scan and Motor Tips Scan and Motor Dialog Box Scan Tab The Scan tab lets you control the dimensions, location, orientation and rate of the scan Graph This area depicts the X/Y scan range based on the other settings on this tab. The total grid area is the X/Y range of the current scanner. The yellow box indicates the scan area within that range. Overscan and Hysteresis are also depicted. Size (m) This control sets the length of the scan in the X (fast scan) axis. The Y size will be based on the ratio of X to Y Resolution . If Square is selected in the Advanced Tab then Size will set the length of both the X and Y scan lengths. The scan size can be increased until one of the axes reaches the maximum range for the current scanner. The size of the yellow box in the Graph will change to reflect the scan size settings. You can use Smart Index Controls to adjust this parameter. X & Y Offsets These values shift the scan area in the X (fast scan) and Y (slow scan) axes. Negative values move the scan area to the left or down, and positive values move the scan area to the right or up. The location of the yellow box in the Graph will change to reflect the Offset values. You can use Smart Index Controls to adjust this parameter. Scan Speed This value sets the Y (slow scan) speed, in units of lines per second. This is the number of full horizontal (X) scan lines completed per second. A lower scan speed typically improves image quality. The upper Scan Speed limit depends upon the Resolution , Overscan settings and Hysteresis. For example: With 4096 pixels, the maximum Scan Speed is 3.1 lines per second. At 256 pixel resolution, the maximum scan speed is 48.8 lines per second. However, scanning at 256 pixel resolution at 3.1 lines per second will improve image quality significantly....
