Note To ensure proper device operation, DC-coupled channels on the NI 5761 must see 50 Ω 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 programming the bias DACs, refer to the NI 5761 CLIP topics in the
NI FlexRIO Help .
