Single Channel Analyser Type : SC530 manufactured by NUCLEONIX is designed primarily to be a constituent unit of Modular Gamma Ray Spectrometer Type : GR611M.
Single Channel Analyser SC530 is essentially used for pulse height analysis. It has THREE modes of operations namely INTEGRAL, NORMAL & WINDOW. In Gamma Ray Spectrometer the scintillation detector pulse output is proportional to the Gamma Energy and hence accurate measurement of pulse height by Single Channel Analyser will give the energy information. 
Features
 Accepts both positive unipolar or bipolar pulses as input
 Modes : INTEGRAL, NORMAL & WINDOW modes of operation
 Discriminator : LLD & ULD
 Output : Positive TTL
 Window width constancy, better than 30mV
