Abstract
A minicomputer−based system for obtaining ’’absolute values’’ of tunnel conductance σ to one part in 105 and simultaneous measurement and ’’calibration’’ of its rate of change dσ/d V is described. The analog, digital, and interface hardware along with the necessary software are discussed in detail and typical results are shown for the system used. The system is capable of presenting the calibrated results in only a few minutes after each sweep is completed, yet requires less than 8 k of core memory, provided a mass storage device such as magnetic tape is available.Keywords
