The PCI-5640R is an intermediate frequency (IF) transceiver with an FPGA. When used with the provided driver, the FPGA is configured to provide access to both analog input (AI) and analog output (AO) channels. This FPGA is configurable if you use the LabVIEW FPGA module to program it. This section contains hardware reference information and an overview of the hardware functions of the PCI-5640R.
