Note About DAQ Cards

• DAQ 2-3: After you add two channels, you may receive the following:

Warning: This hardware could not support the requested value of 1000.00 for 
SampleRate. SampleRate has been set to 500.00.

Your program will still work, just slower. This is an issue with the drivers on some of the computers and does not represent a problem for this lab.

Circuit for BasicAIO

Circuit layout for BasicAIO (two measurements).

Graph from BasicAIO

Graph showing outputs when

Vout0 = 2.5+2.5*sin(2*pi*k/100);
Vout1 = 2.5+2.5*cos(2*pi*k/100);

That is,

\( \begin{align} V_{out,\,0}=2.5+2.5\sin\left(\frac{2\pi k}{100}\right)\\ V_{out,\,1}=2.5+2.5\cos\left(\frac{2\pi k}{100}\right) \end{align} \)

Circuit for AIO

Circuit layout for AIO (six measurements).

Graph from AIO

Graph showing outputs from six measurement channels.
