NI 5450 Calibration Procedure
You have finished verifying the vertical gain accuracy of the
NI 5152/5153/5154.
Programmable Vertical Offset Accuracy
(NI 5152 Only)
Complete the following steps to verify the programmable vertical offset
accuracy for each NI 5152 channel.
1.
Open a session and obtain a session handle using the niScope
Initialize VI.
2.
Configure the input impedance and the maximum input frequency
using the niScope Configure Chan Characteristics VI.
