Detailed Description
The WaveformGenerator component is a multi-functional waveform signal generator. It can be used to generate sine, triangle, square or sawtooth waveforms.
Properties
| Property | Description |
|---|---|
| WaveType | Waveform type to generate. Select between:
Note: Digital pulses (values changing between 0 and 1) can be generated using Square and setting Amplitude=0.5 and Offset=0.5 |
| UseHwClock | Set to true to use more accurate (but slower) hardware time source |
| fs | Generator running frequency (affects the waveform granularity) |
Parameters
| Parameter | Description |
|---|---|
| Amplitude | Amplitude of the generated waveform |
| Frequency | The frequency [Hz] of the generated waveform |
| Symmetry | Waveform rise/slope symmetry [%]
|
| Offset | The offset of the generated waveform |
| PhaseShift | The phase shift of the generated waveform (in rad degrees) |
Signals
| Signal | Description |
|---|---|
| Output | Generator output (generated waveform) |
| Time | Time in seconds since generator start or restart |
Messages
| Message | Description |
|---|---|
| CM_SUSPEND | Suspend waveform generation. The last generated value will be held in the output. |
| CM_ACTIVATE | Resume waveform generation. |
| Restart | Restart the waveform generation (and zero the Time signal) |
