Occupied Bandwidth Measurement

selected, the vertical divisions are scaled in logarithmic units. Scale Type (Lin) scales the
vertical divisions linearly, and sets the default amplitude units to volts.
Y Axis Units
Displays the menu keys that enable you to change the vertical (Y) axis amplitude unit. The
analyzer retains the entered Y Axis Units separately for both Log and Lin amplitude scale
types. For example, if
Scale Type has been set to Log, and you set Y Axis Units to dBm,
pressing
Scale Type (log) sets the Y Axis Units to dBm. If Scale Type has been set to Lin and
you set
Y Axis Units to V, pressing Scale Type (Lin) sets the Y Axis Units to V. Pressing Scale
Type (Log)
again sets the Y Axis Units back to dBm.
dBm Sets the amplitude unit for the selected amplitude scale (log/lin) to dBm.
