16. Move the calibrator test head to the digitizer input channel 1 and repeat steps 2 through 15
for every configuration in Table 3, changing the value of the channelList parameter from
"0"
to
"1"
.
17. End the session using the niScope Close VI.
You have finished verifying the vertical gain accuracy of the NI 5122/5124/5142.
Programmable Vertical Offset Accuracy
Complete the following steps to verify the programmable vertical offset accuracy for each
digitizer 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.
