I am currently calibrating PXI cards using Calibration Executive (3.2.2) and a PXI-1050 Chassis, my company is getting ready to start buying PCI cards, specifically PCI-6542 and PCI-6713. What additional equipment will I need to purchase so that I will be able to calibrate the PCI cards? If the PC I am currently using does not have enough slots to accomodate additional cards is it necessary to buy another PC or is there a chassis that will let me calibrate the PCI cards outside of a PC?
