Analog Discovery 2 With Waveforms

[andrewshivers]

Hi, 

I'm looking at purchasing a Analog Discovery Two; and I downloaded Waveforms to play around with it a bit before I bought the hardware to see what it could do. I do have one question that I can't figure out:

For the pattern generator function according to the specification found here: https://reference.digilentinc.com/reference/instrumentation/analog-discovery-2/specifications

Digital Pattern Generator

Channels: 16 (shared)

Sample rate (real time): 100 MS/s

Algorithmic pattern generator (no buffers used)

Custom pattern buffer/channel: up to 16K samples

Output logic standard: LVCMOS (3.3V, 12mA)

Data file import/export using standard formats

Customized visualization for signals and buses

It says that the buffer is 16K samples, but when I try to do it in Waveforms, it maxs out at 1.024K samples. Is it 16K total, 1K for each channel? Or am I missing something?

Hi @andrewshivers,

That is a limitation of the Demo mode; when you initially boot up WaveForms and select demo you are limited to each of the 16 channels to having 1k buffer each. With an AD2 connected, you would be able to select configuration 4 which gives you the 16k sized buffer for each of the 16 channels.

Let me know if you have any further questions.

Thanks,
JColvin
