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].
