4-3-4-4 Optimizing M-Mode
The use of preset gives optimum performance with minimum adjustment. If necessary, the following
controls can be adjusted to further optimize the M-Mode display:
•Adjust Horizontal sweep to optimize the display resolution.
•Adjust Gain and TGC controls to adjust the range to be imaged.
•Use the Frequency (move to higher frequencies) or the Frame rate control (move to lower frame
rate) to increase resolution in image.
•Adjust Dynamic range to optimize the useful range of incoming echoes to the available greyscale.
•Adjust Compress to further optimize the display.
•Adjust Reject to reduce noise while taking care not to eliminate significant low-level diagnostic
information.
