Description

428 Keithley Amplifier Other UsedFeatures: 2s rise time 1. 2fA RMS noise Up to 1011 V A gain IEEE 488 interface This Current Amplifier converts fast, small currents to a voltage, which can be easily digitized or displayed by an oscilloscope, waveform analyzer, or data acquisition system. It uses a sophisticated feedback current circuit to achieve both fast rise times and sub picoamp noise.

and constant current operation
