PXI-4110: Possible to independently configure +20V and -20V supplies?

Go to solution

With regard to the PXI-4110.... Is it possible to configure the +20V and -20V supplies non-complimentary? For example:

  • +20V supply is set to +10V
  • -20V supply is set to -5V

Also, in this configuration, could one supply be turned ON or OFF independent of the other? 


If so, any special programming notes to set parameters such as these?


Thank you.

Yes, the 4110 has three channels that are independent of each other each supplying a DC voltage. They can be programmed to values non complimentary of each other. You could program channel 1 to +10V and channel 2 to -5V then turn off channel 2 and only have channel 1 outputting +10V.


You can find examples for configuring current and voltage at the following link.



I hope this helps!
