Regarding analog voltage signal acquisition using NI PXI 7851R and SCB 68A breakout box

[Theatom]

Hi Guys, 

I am using NI PXIe 1062Q chassis and PXI 7851R card with breakout box SCB-68A.

I want to feed in time-varying analog voltage and want to measure it using the above-mentioned components.

In PXI 7851 R manual, it is given that the analog voltage range can be within +/- 10 volts, but not understanding what is the current range.  

looking for your kind help.
