| CMCA-550 |  Data Acquisition Module for Mössbauer Spectroscopy |  | The CMCA-550 module is designed for operation with Personal Computers
running under Windows XP - Multichannel scaling (MCS) mode for taking Mössbauer spectra
- Pulse height analysis mode using an integrated analog-to-digital converter
- An energy window, set in PHA mode, is available in the MCS[window] mode when acquiring Mössbauer data
- WISSOFT 2003 software controls up to four CMCA-550 modules, connected to one PC
- Folding of Mössbauer spectra
- Evaluation of data from Mössbauer Velocity Calibrator
- Communication with PC by USB interface and RS-232C interface
- Power supply separate from PC: Data acquisition is continued when the PC is switched off
- In case of power failure the acquired data is stroed for more than 4 days
- Flexible and service-friendly by highly integrated circuit
