The following subsections provide in-
structions for the M mode operation
while the M trace is active.
9.3.1 M Gain
Only when the M trace is updating can the M mode gain be changed. Note that
the M gain is different from the B mode (2D) gain.
The M gain controls the overall brightness of the M trace, it determines how much
the amplification of the echoes is.
Turn the GAIN knob to adjust the M gain.
 Remark:
• The M gain value is shown at the M Mode Image Info area (the GN).
9.3.2 Sweep Speed
SWEEP SPEED
Use this function to adjust the speed of sweeping in the M mode. The larger the
sweep speed is set, the faster the M trace is updating.
To adjust the sweep speed, highlight SWEEP SPEED in the M mode menu, and press
the LEFT/RIGHT key to reduce/increase its value.
