7.12 System Setting
7.12.1 X Axis Unit Settings
In "Arbitrary waveform editing tool," you can use time and user-defined unit in addition to the address
of waveform data as a unit for displaying/setting horizontal axis.
Time coordinates with [Freq].
For a user-defined unit, you can arbitrarily specify the start point and end point of the waveform data
and name of the unit.
Some examples of user-defined units for the horizontal axis are listed in Table 7-6.
When you use mathematical expressions to generate the waveform, it is useful to use values from 0 to
6.283185 because the unit of the trigonometric function such as sin() is radian.
Click the button on the right of [Unit] to display a list of available units for the horizontal axis.
Select a unit of horizontal axis by clicking in the list, or pressing

key.
Selecting a user-defined unit as the unit of X axis allows you to specify [Name], [Min], and [Max].
In the area on the right of the [Name], enter a string of up to 4 characters (2 two-byte characters) as the
name of the unit of horizontal axis.
In the areas on the right of the [Min] - [Max], enter the minimum value (the value at the left end of the
waveform) and maximum value (the value at the right end of the waveform) of the user-defined unit.
