Timing Accuracy
Complete the following steps to verify the timing accuracy for the NI 5114.
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.
3. Configure the common vertical properties using the niScope Configure Vertical VI.
