Vertical Offset Accuracy
Complete the following steps to verify vertical offset accuracy of the NI 5114. You must verify
both channels with each iteration listed in Table 5.
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 the maximum input frequency using the
niScope Configure Chan Characteristics VI.
LabVIEW VI C/C++ Function Call
