The NI-5772 ships with socketed CLIP items that are used to add module I/O to the LabVIEW project.
The CLIP also contains an engine to program the ADC and Sample Clock circuit, either through predetermined settings for an easier instrument setup, or through a raw SPI address and data signals for a more advanced setup. Access 12-bit analog input data using an I16 data type (left-justified). The DIO signals are grouped into two ports of four signals each and are accessed using a U8 data type and a Boolean write enable signal. The four PFI signals are accessed individually using Boolean indicators.
Although real-time sampling is the default sampling mode on the NI-5772, the NI-5772 CLIP also supports Time-Interleaved Sampling (TIS) on one analog input channel at a time. TIS enables the device to use both channels on the ADC to sample the same input channel at different relative phases, which doubles the real-time sampling rate. The NI-5772 then interleaves the samples to create a waveform as if only one ADC channel was sampling the waveform at twice the Sample Clock rate. The data is returned on the AI 0 Data <N..N-3> and AI 1 Data <N..N-3> signals even though the device is only sampling the single analog input channel that you selected.
The following figure demonstrates TIS on an NI-5772 device.
This CLIP also enables you to synchronize two or more modules using an external reference.
