Control Computer/Software
A state of the art PC, optimized for AFM operation, is included with the Nano-DST™ system. Reliability is assured with computers configured by Dell™. The computer system includes ample disk drive capacity to store AFM images and to transfer them to a CD when desired. A 19” LCD monitor is also included.
The Nano-DST™ command and control software, derived from SPM Cockpit™, is in use in hundreds of laboratories throughout the world. The software operates in two modes:
• EZ Mode™ for beginners and casual users
• X’pert™ Mode for advanced AFM operators
Signals may be monitored with the Signal Access Console that connects to the rear of the electronic
controller. All signals associated with the performance of the Nano-DST™ are available.
Environmental
Vibration Solution: The highest performance is assured when the optional acoustic enclosure and vibration table are used with the Nano-DST™.
