The PCI-16AIO168 board provides high-speed 16-bit analog input/output resources in a standard PCI module. Eight analog output channels can be updated either synchronously or asynchronously, and support waveform generation. Each analog output channel contains a dedicated 16-bit D/A converter and an output range control network. The board receives analog output data from the PCI bus through a 32K-sample FIFO buffer.
The analog inputs are software-configurable either as 16 single-ended channels or as eight differential signal pairs. Buffer amplifiers on all input lines eliminate multiplexer input switching noise, and minimize crosstalk and input bias currents. Analog input data accumulates in a 32K-sample buffer until retrieved through the PCI bus.
Internal auto-calibration networks permit the calibration of all analog input and output channels without removing the board from the system. Gain and offset corrections of the analog input and output channels are performed by calibration DAC’s that are loaded with channel correction values during auto-calibration. Software-controlled test configurations include a loopback mode for monitoring any analog output channel. Trigger input and output connections support external triggering and multi-board synchronization.
