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).
