What is the small amplitude that can be generated with the diligent analog discovery 2?

Can I generate ramp waves with amplitude of 2mV?

Hello,

I apologize for the delay. Yes, you can generate ramp waves with an amplitude of 2 mV.

You can always use the built-in demo mode of WaveForms (freely available for download here: https://digilent.com/reference/software/waveforms/waveforms-3/start) to see what is possible to do with the software/hardware.

The Analog Discovery 2 itself has an absolute resolution for amplitudes less than 1 V of ~166 uV as per here: https://digilent.com/reference/test-and-measurement/analog-discovery-2/specifications#arbitrary_waveform_generator. The signal itself will likely not look that clean at such a small amplitude though

Let me know if you have any questions.

Thanks,
JColvin

Hi @AFEdebug

For such low amplitude signals you should use some attenuation like resistive voltage divider.
