What if I need to purchase a GPIB card?

For use with VNA Cal Kit Manager, the GPIB-PCII/IIA card from National Instruments is a good deal at $395, provided your computer has an open ISA slot. It can be configured to work without IRQ or DMA if you use its "Basic Configuration 4 " in the Windows 95 Device Manager. Change the switches and jumpers as explained in Appendix A of the " Getting Started with Your GPIB-PCII/IIA and the NI-488.2 Software" manual. Be sure to purchase the model with the correct software driver for Windows 95/98.

Alternatively, purchase one of the PCI or USB GPIB products from NI or Hewlett-Packard. These are truly plug and play, and will not require any additional IRQ or DMA resources.
