NI 5122/5124/5142 Calibration Procedure
Trigger Sensitivity
Complete the following steps to verify the trigger sensitivity of the NI 5122/5124/5142. You
must verify channel 0, channel 1, and the external trigger channel using the corresponding
iterations in Table 14.
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.
