Since Windows is not a multitasking operating system you must be careful about what you do while acquiring data to avoid missing a sampling interval. Because Embed calculates all blocks before it begins each sampling interval, any one block that runs slowly can disturb the acquisition process. Additionally, since there is only one processor to calculate and draw the Windows graphics, you should avoid any operation that causes Windows to repaint the screen. These operations include:
•Running DOS shells
•Digital display read-outs, strip charts, histograms, meters, and plots for greater than 200 Hz sampling rates (shown in order, from most costly to least costly)
•Calling up a block’s Properties dialog box
•Expanding a plot to full screen
•Changing diagram layers
