Keithley The Model 428-PROG Programmable Current Amplifier converts fast, small
Keithley The Model 428-PROG Programmable 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. The gain of the Model 428-PROG is adjustable in decade increments from 103V/A to 1011V/A, with selectable rise times from 2¦s to 300ms. 2¦s rise time 1.2fA rms noise Up to 1011 V/A gain IEEE-488 interface Fast response at low current levels Incorporates a second-order Bessel-function filter that minimizes noise without increasing rise time on high-gain ranges Can be connected to an oscilloscope or waveform digitizer to display very low currents in real time Simple front panel operation with LED indicators, and selectable display intensities reconditioned
