I have the NI6259 and want to read an analog signal.
I connect DC voltage 0.35V to the AI0 analog input pin of NI6259 through a BNC connector. The ground pin of the signal generator is connected to the ground pin of the BNC adapter.
The measured signal is oscillating. Could anyone help to explain? It should be a constant voltage. Thank you.
