The GX3216’s input channels are sampled simultaneously. Each channel’s sampled data is accessed via the PCI bus and a 256 K-Sample FIFO buffer. Sampling can be controlled in groups of 1 through 16 channels, and the sample clock can be generated either from an internal rate generator, software or an external source. Both burst and continuous sampling modes are supported. The two output channels can also be clocked at rates up to 1 MS/s and like the input channels, offer programmable ranges. Output clocking can be synchronized to analog input sampling.
The module supports an auto-calibration routine which applies any required offset and gain correction values for all input and output channels. Additionally, a self-test input switching network routes output channels or calibration reference signals to the analog inputs – verifying module integrity and functionality.
