Description
The GP-LC-4X ARB block is used to assign a periodic arbitrary waveform signal to the GP-LC-4X DAC using the output DMA.
Ports
Input
#
En
—
flag to allow overwriting of array with waveform
scalar
Details
Re-shaping of the signal will only take place when this input is set to one.
| Data types |
|
| Complex numbers support |
No |
#
Input array
—
array of elements 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, an array of 100 elements must be prepared, a 1kHz signal must be prepared with an array of 1000 elements, etc.
| The maximum size of this array is one million elements, which corresponds to a 1Hz signal. |
