Abstract：Signal Conditioning is an important part of signal gathering systems. In the term it realizes

synchronization gathering in high amplifying and several different filter cutoff frequencies by the

research of signal conditioning module(AMC3301) and special SCP bus. The signal conditioning module can 

be used with a AMC2315 Algorithmic Closed Loop Controller by special SCP bus. And the SCP bus technology

have be applied in some modules and systems.
Key words: Signal Conditioning Plug-on(SCP); Sample & Hold; lowpass Filter; cutoff frequency; special SCP
