Horizontal sweep
Adjusts the horizontal refresh rate of the M-Mode area of the
display. Horizontal sweep does not change the acquisition
resolution, so that user can change the horizontal sweep in
replay (with no loss of quality).
On some low fre-
quencies, the sys-
tem switches
automatically to
second-harmonic
mode. The word
“Octave” appears
in the status win-
dow.

Rotate the knob clockwise to increase the frequency. The
selected frequency is displayed in the status window. For some
probes/applications the lowest frequency settings will be
