DC voltage on inputs of NI5761-2 ?

[Henrik_Volkers]

The Spec tells :

Note To ensure proper device operation, DC-coupled channels on the NI 5761 must see 50Ω at DC

looking back at their source. If you are connecting a to source with an output impedance less than 50 Ω,

you can add series resistance close to the source to properly bias the NI 5761 input terminals.

You can also use the NI 5761 input channel bias DACs

to remove DC offset

present in the system.

For more information about progr

amming the bias DACs, refer to

the NI 5761 CLIP topics in the

NI FlexRIO Help
