In a computer controlled impedance setup, the current sensitivity of the Solartron SI-1260 Impedance/Gain Phase Analyzer is improved by six orders of magnitude by the Keithley 428 Current Amplifier. Impedances up to the order of 1013 R can be measured at low frequencies with the ac signal of 30mV rm
