Issue Details
The NI 9215 has the following input impedance specifications.
| Input impedance |
|---|
| Resistance |
|---|
|
NI 9215 with screw terminal (AI-to-COM)
|
1 GΩ
| |
NI 9215 with spring terminal (AI-to-COM)
|
1 GΩ
| |
NI 9215 with BNC (Between any two AI- terminals)
|
200 kΩ
|
|
In the case of screw terminals and spring terminals, it is between the AI and COM terminals, and in the case of BNC, it is between the AI- terminals of different channels, but there is no description of the input impedance between AI+ and AI- terminal.
What is the AI+ and AI- input impedance of the NI 9215?
