428 Keithley Amplifier Other

Used

The 428 is an Amplifier from Keithley. An amplifier is a type of electronic test equipment that amplifies radiofrequency (RF) and microwave signals using the antenna. Amplifiers are ideal when used for electromagnetic interference (EMI) testing, cell phones, microwaves, radio communications, and other such applications.

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.
