Sample rate for Analog Discovery 2 with MATLAB

[Junfei Li]

Hi,

I am trying to use analog output and oscilloscope and record the data with Matlab using Analog Discovery 2. I am generating and recording signals at ~500kHz, so I want to set the sample rate as 100MS/s. With WaveForms, I can reach this sample rate, but when I set the sample rate with Matlab code,

s = daq.createSession('digilent')
ch_out = addAnalogOutputChannel(s,'AD1', 1, 'Voltage')
rate = 1e8;
s.Rate = rate;

The following error pop up:

Rate cannot exceed 1000000 in the current configuration.

 

How can I resolve this problem?

 

Thanks

Junfei

Hi @Junfei Li,

I've moved your thread to a section where a more AD2/WaveForms experience engineers look.

cheers,
