4.6.2 Setting display scale
There are two (2) alternatives available in the display scale setting: the auto scale and the manual
scale.
a) Auto scale
Use the menu [Graph][AUTO SCALE] and set it [ON]. The scales of x axis and y axis will
automatically be adjusted at optimum according to analyzed data. Set the initial display range
at measurement through using the menu [Graph][SCALE].
b) Manual scale
Use the menu [Graph][AUTO SCALE] and set it [OFF]. Then, the auto scale function
becomes invalid and the display range will be fixed at the state that has been set through
[SCALE].
When the x axis is assigned for frequency in the graph, the displayed range in the x axis will
always be the sweep frequency range specified by [MIN FREQUENCY] and [MAX
FREQUENCY] in the menu [Measure][SWEEP FUNCTION], irrespective of the ON/OFF status
of the auto scale [AUTO SCALE].
4.6.3 Setting grids
Use the following menus, which are located in the level just below the menu [Graph] to set the
grid display:
[GRID] : When this is [ON], grids are displayed.
[GRID TYPE] : Solid lines are displayed at the setting of [SOLID LINE] and broken line
are displayed at the setting of [BROKEN LINE].
[GRID STYLE] : This enables to select appropriate styles of grids to be displayed.
[X] : Grids are displayed only for the X-axis.
[X-Y1] : Grids are displayed both for the X and Y1 axes.
[X-Y2] : Grids are displayed both for the X and Y2 axes.
[X-Y1-Y2] : Grids are displayed for all of the X, Y1 and Y2 axes.
Note that this last selection is valid only when the selected graph display mode ([Graph][DISPLAY
MODE]) involves both gain and phase; i.e., “logF-dBR-
 ”, ”F-dBR-  ” or ”F-R-  ”.
