Keithley 428 Current Amplifier
Keithley 428 Current Amplifier
Product Overview
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.
Features:
- 2μs rise time
- 1.2fA RMS noise
- Up to 1011 V/A gain
- IEEE-488 interface
