  • PXIe-4135
  • SMU/FET Cable-Chip DUT
  • Power Supply

Issue Details

I am trying to understand the maximum capacitance that can be connected to the PXIe-4135.
I want to know if there are specification limits for capacitance on the HI and guard terminals, and whether adding capacitance will affect stability, response, or accuracy of the device.

Solution

The NI PXIe-4135 is primarily intended for DC measurements and sourcing applications. It can adjust SourceAdapt parameters to maintain stability when capacitance is connected to the HI terminal. Proper tuning enables the device to operate across a wide range of capacitance values. So that the NI PXIe-4135 does not define a fixed maximum capacitance value.
