NI PXI Switch Matrix capacitance

[Elamaran]

Hi all,

I am doing a feasibility study for using a NI PXI crosspoint switches for Switching (connecting) different capacitance values to the input pins of a Device. The device is sensitive to capacitance value of 0.1pF. So any additional parasitic capacitance (Cp) added to the device by the Switch will seriously affect the functioning of the Device.

Based on the following NI article, it seems that the Switching setup might add up to some uF of Cp to the system. 

I am trying to findout more details on using a switch for this purpose.
