Table
Table results interfaces are primarily used in conjunction with the various low-speed serial decoding
options, such as CAN, I2C, SPI, UART, etc. When the table is displayed, the user has access to information
about the messages decoded for the last acquisition. Retrieving data from the Table interface involves
some knowledge of the table’s structure, in terms of the columns that are displayed and the cell types.
The CellType and CellValue are the key properties to use to retrieve the table’s data. See the information in
the CellValue property for more information.
Example paths to Table Result interfaces:
app.SerialDecode.Decode1.Out.Result
app.SerialDecode.Objects("Decode2").Out.Result
Waveform
Waveform Results interfaces can be found wherever there are basic Voltage vs. Time waveforms.
Examples include channel (Cn), memory (Mn), math function (Fn) and zoom (Zn) traces, as well as others
that are associated with specific analysis packages, such as the Power waveform used in the PAS
package. In general, these waveforms are usual voltage vs time, unless a current probe or other method of
changing the vertical units (e.g., the Rescale Math function) is employed. The key property in the
Waveform interface is the DataArray, which is a 1D array containing the value of each sample in the
waveform.
Example paths to Waveform Result interfaces:
app.Acquisition.C1.Out.Result
app.Acquisition.Channels("C1").Out.Result
app.Math.F2.Out.Result
app.Zoom.Z3.Out.Result
app.SDA.Btub.Out.Result
Note: Traces like F2 and Z3 can hold plots, like histograms, which do not use the Waveform
interface.
XY
The XY interface is used on XY waveforms. Users can create an XY waveform by selecting this option in
the Display Setup… screen. XY waveforms allow you to see how the signal on one channel moves in
relation to another. The key property is the DataArray, which is a 2D array that returns the voltages on the
X and Y sources for each XY pair.
Example path to the XY Result interface:
app.Math.XY.Out.Result
