SINGLE CHANNEL ANALYSER - [ Type : SC 530 ]
Technical Data

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
