8.5.6 Vertical axis unit
In the ARB, the voltage and the user unit can be used as the display/setting unit of vertical axis in
addition to the waveform data (16 bits:
32768 to +32767).
The voltage is interlocked with [Amplitude] and [DC Offset] in [Power Setup].
For example, this function is useful when creating a waveform through interpolation by setting the
voltage to the vertical axis and the time to the horizontal axis.
In the user unit, any value can be set at the beginning and end of waveform data as well as the unit
name.
When a numerical expression is used to generate a waveform, it is useful to use
1 to +1 because the
maximum value of trigonometrical functions such as sin() is ±1.
Click the [Unit Setup] tab on the system setting screen or press Alt + U to activate the [Unit
Setup] page.
Click the
button to the right of [Unit(X)] to display the list of selectable vertical axis units.
Click one in the list or press the     keys to select a vertical axis unit.
When the user unit is selected as a vertical axis unit, [Name], [Min to Max] can be set.
Input a string consisting of up to four 1-byte characters (or two 2-byte characters) as the name of the
vertical axis unit in the area to the right of [Name].
Input numerical values for the minimum value (lowermost value of waveform) and maximum value
(uppermost value of waveform) for the user unit in the areas to the right of [Min to Max].
8.5.7 File operations
The settings for the system setting screen are saved to a file or read from a file.
The system setting file for the ARB is a binary file in the unique format and cannot be used in other
applications.
Select [System Setup File] - [Save] ( Alt , F , S or Ctrl + S ) on the system setting screen to
display the screen titled [Save As].
Select a saving location, input a file name and click the
Save button. The file extension is “.ocb”
and can be omitted at file name input.
To read the system setting file, select [System Setup File(F)] - [Open] ( Alt , F , O or
Ctrl + O ).
When the screen titled [Open File] appears, select a file location, input a file name and click the
Open button.
Other files that can be handled with the ARB “7.6.1 File type”
