4. Set the AO Gain parameter according to the values from Table 14.
Table 14: AO Attenuation
AO Attenuation (dB) AO Gain (dB)
0 0
10 -10
20 -20
30 -30
5. Create an array of 20000 points and fill every element with value 0.
6. Write the array to AO and start the task.
7. Measure the output voltage with the DMM.
8. Stop and clear the task.
9. Compare the result with the limits in Table 11.
