Figure 4-5. Input Range Optimization

During post-processing analysis, the range which provided the best resolution at any point in time is instantly available.

The cost of a CIO-DAS16 and CIO-SSH16 is less than the cost of an A/D board with a channel gain queue and far less than alternative simultaneous sample & hold schemes. It certainly is more flexible.

4.4 SAMPLE & HOLD

You probably purchased the CIO-SSH16 for it's simultaneous sample & hold (S&H) feature, and that was our primary design objective (Figure 4-6). The theory of operation is simple. Sample & hold chips on each channel are synchronized to the analog input boards sample & hold chip via pin 26 of the analog input board (SSH OUT).
