Vertical Offset Accuracy
Complete the following steps to verify vertical offset accuracy of the
NI 5152/5153/5154. You must verify both channels with each iteration
listed in Table 3 (NI 5152) or Table 4 (NI 5153/5154).
1.
Open a session and obtain a session handle using the niScope
Initialize VI.
Note
Throughout the procedure, refer to the C/C++ function call parameters for the
LabVIEW input values.
2.
Configure the input impedance and input frequency for the channel
using the niScope Configure Chan Characteristics VI.
