Discusses the design and construction of a quasilogarithmic current-voltage converter which allows currents spanning an exceptionally broad range from 10 pA to 10 mA with a bandwidth greater than 2 kHz to be measured. Design considerations and results; Ideal use of the converter for studying local interactions in scanning tunneling microscopy.
