428 Keithley Current Amplifier
Features:
2μs 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.
