Keithley 428
Current Amplifier
Description
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.
It uses a sophisticated feedback current circuit to achieve both fast rise times and sub-picoamp noise.
