Specifies a periodic arbitrary waveform to the GP-LC-4X DAC using the output DMA.
Description
The block is used to specify a periodic arbitrary waveform signal to the GP-LC-4X DAC using the output DMA.
Ports
Input
En -.
flag to allow overwriting the array with a waveform
scalar
Details
Signal re-shaping will only occur when this input is set to one.
| Data type |
|
Input array -
array of elements (data type Float64) with the shape of one period of the signal required for playback
vector
Details
The sampling frequency of the DAC is 1MHz, so to reproduce a 10kHz signal you need to prepare an array of 100 elements, a 1kHz signal you need to prepare an array of 1000 elements, etc.
| The maximum size of this array is one million elements, which corresponds to a 1Hz signal. |
Array size -
size of the above array in elements
scalar
Parameters
Module number -
unique module identification
1 (by default) | 2 | 3 | 4 | 5 | 6 | 7 | 8
Details
Used when more than one I/O module of the same type is installed in a real-time machine.
Channel number -
number of the analogue output channel on which this signal will be generated
1 (By default) | 2
Calculation Step -
calculation step in seconds for sending counts to digital output channels from the real-time application
`-1 (By default).
