Hi,

I am using PXI 8881 with a VDG(PXI5551) and VST (PXi 5841).I want to use both these devices from Host pc.How can I connect with VST from host PC?

also what is remote VISA and remote gRPC?

I am new to PXI chassis and it would be very helpful if someone can recommend me some books or materials for reference and having good understnading on this.

Thank you in advance
