INTRODUCTION
The CAPTUS
®
4000e includes a fully functional multichannel analyzer (MCA) board. The
MCA Module provides custom control of the MCA parameters and data acquisition for
special applications:
• All MCA parameters are software controlled.
• Up to 16 Regions of Interest (ROI) can be defined at one time.
• Counting can be performed using live time, real time or peak counts.
• Spectral data and MCA settings can be saved to hard disk.
• Count data and the spectrum can be printed.
