Power supply

[paofthree]

Is the PXI-4110 power supply compatible with the PXI-4130? I have two PXI-4130 cards and either one or both has gone bad. I have noticed that the PXI-4130 is no longer available for purchase.

Compatible in what way?  The PXI-4130 is a Source Measure Unit (SMU) while the PXI-4110 is a Power Supply.  SMUs are made for making accurate measurements on the output voltage and current while the power supply is just trying to get current out.  So the real question is what do you want out of the device?

The PXI-4130 is being used as a power supply in our system. We have two that are used in tandem to supply up to 36V for the unit under test. One of them has failed so I need to replace it.  Thanks for pointing out that it is an SMU since I did not find it under power supplies. I do not know why the designer of the system chose an SMU instead of a regular power supply.
