There are two high-speed Digital I/O PXI cards in the UX7000 range, with the choice of 16 or 32 TTL port widths. Each group of 16 channels can be user programmed as either port input or output. Channel handshaking is not possible. The cards are mainly used for digital recording or test pattern generation with a Device Under Test (DUT) in the electronics or semiconductor industry. The 125 MHz maximum clock rate on 16 channels, and the 60 MHz maximum clock on 32 channels makes these cards the fastest in their class.
