2.3 WaveForm Tab
WaveForm Tab obtains A/D conversion values from the EVB with serial communication and display a
waveform graph. In addition, it is possible to save the obtained A/D conversion values in a file, and read
saved A/D conversion values to display a graph.
A/D conversion values can be measured during up to 1 hour with the output data rate of 15625 SPS.
The WaveForm Tab consists of the following three areas as shown in Figure 2-4.
1. Graphical display area
2. Operation buttons
3. Setting area
Figure 2-4 WaveForm Tab Screen
2.3.1 Graphical Display Area
In this area, A/D conversion values are displayed as a waveform. The horizontal axis indicates the time, the
vertical axis indicates the conversion value. The value displayed on each axis depends on the settings in the
"X-Axis" or "Y-Axis" group in the setting area.
The graph is updated to the latest values when the scroll bar is positioned at the right end while A/D
conversion values are being obtained from the EVB.
Note: Display update may be suppressed to prioritize obtaining A/D conversion value. During suppression,
the graph and measurement value are not updated. Suppression condition can be specified by
“UpdateRestriction” parameter in the “WaveForm” section of the configuration file. Refer to “0
Configuration File” in detail.
