Custom Waveform Generation for a Large Number of Data Samples


s0890331

Question

Hello,
I am using Analog Discovery 2.
I am using Wavegen from Digilent Waveforms to generate an analog output. My data samples size is 150k to 200k which I want to output at 5 ms interval. To do so when I select custom waveform option and import my csv file (with normalized data) only first 65536 samples get imported. Is there a way to change the size limit or any other option in Wavegen which I can use for this size of sample data?  

I have attached my data sample file for reference.


Thankyou.

Hi @s0890331

The AD2 Wavegen device buffer size is 16k samples with the 3rd configuration. The imported waveform is scaled to the device buffer size. The application imports up to 64k samples, so you should scale down waveforms with external app or using the WF/Script tool.
For more samples and lower rate you could use Wavegen Play, data streaming to device.
AD3 is up to 32k and samples do not to be stretched.
ADP3X50 is up to 64k and supports buffered Play for up to 32M samples with the device DDR-RAM at up to 125MHz.
