ACQUISITION

• data acquisition from LOA10-AES or lock-in via serial RS232 port
• control of lock-in functions: sensitivity, time constant, phase and harmonic
• control of scan voltage by setting: start voltage, end voltage and scan rate (connection with AUS200 required)
• control of modulation voltage by analog voltage setting to internal oscillator (connection to LOA10 or AUS200 required)

MEASUREMENTS AND DATA PROCESSING

• real time plot of Auger signal v.s Energy on computer monitor
• signal numerical values monitoring
• one window plot of 10 different AES spectra
• calibration of the Energy scale
• measurements of relative values of the signal
• manual peak selection for composition calibration with verification of selection
• composition calculation based on selected peaks and data base of relative sensitivity factors
• zoom in/out of the selected section of the plot
• AES spectra printing with Lock-in and spectrometer settings
• text writing and editing on the AES spectrum

GENERAL

• Windows 98/NT/2000/XP operating system
• automatic memorization of last operator settings
• standard export file: ASCII
• editing data base file for instrument calibration
• separate utility software to test connection of serial RS232 port
