Waveforms - LabVIEW VI Call Parameters
Waveforms
LabVIEW waveforms, such as Analog Waveforms, Digital Waveforms, and Digital Data, are represented as clusters.
The Analog Waveform and Digital Waveform clusters contain the following elements:
| Element | Description |
|---|---|
| t0 | The initial time. |
| dt | The delta time. |
| Y | The data of the waveform. For digital waveforms, Y is a cluster with two elements, transitions and data. |
| attributes | A variant containing all of the attributes of the waveform. |
The Digital Data clusters contain the following elements:
| Element | Description |
|---|---|
| transitions | The time transition data. |
| data | The digital data. |
You can use the LabVIEWAnalogWaveform and LabVIEWDigitalData TestStand data types to create variables for waveforms.
Note
If the Y element representation of an analog waveform is set to Quad or Unsigned Quad, do not use the LabVIEWAnalogWaveform data type because the representation of the Y element for the type is set to double-precision, 64-bit floating-point, which cannot store a Quad or unsigned Quad value without the risk of losing precision. In these cases, create a new custom data type and set the representation of the Y element to signed 64-bit integer or unsigned 64-bit integer, respectively.
