The Keithley 6430 Sub-Femtoamp Remote SourceMeter combines the voltage and cur sourcing and measurement functions of Keithley’s popular SourceMeter and Source-Measure Unit (SMU) products with sensitivity, noise, and input resistance specifications superior to electrometers. This unique combination of broad functionality and exceptional measurement integrity is made possible by the Keithley 6430 SourceMeter’s Remote PreAmp, which offers a very sensitive bi-directional amplifier with sensitive feedback elements for measuring or sourcing curs at the device being tested. The high level signals output by the Remote PreAmp are sent to the controlling mainframe via a two-meter cable. This allows the user to make a direct or very short connection to the signal, minimizing the effects of cable noise.Features and Specifications of the Keithley 6430 SourceMeter include:

  • Sub-Femtoamp Remote SourceMeter
  • Makes voltage, cur, and resistance measurements at speeds no electrometer can match
  • Measures curs in as little as 5ms on the 100nA range, decreasing to a few hundred microseconds on the higher ranges
  • Excellent low cur sensitivity
  • Remote PreAmp:
    • Can be located at the signal source to minimize cable noise
    • Makes low cur sensitivity useful by eliminating long input cables
    • Is an integral part of this sourcemeter’s feedback measuring system that cannot be operated independently from the measurement mainframe, although it can be separated from the mainframe by up to two meters of connection cable carrying high level signals
  • 0.4fA p-p (4E – 16A) noise (typical)
  • >1016Ω input resistance on voltage measurements
  • High speed — up to 2000 readings/second into internal memory
  • Up to 6½-digit resolution
  • Fast characterization of components with programmable digital I/O and interfaces
  • Provides four-quadrant sourcing of up to 2.2W, as well as measurement sensitivity down to sub-femtoamp and microvolt levels
  • Measure curs from the 1pA range (with just 0.4fA p-p noise) up to the 100mA range at up to 20V
  • Voltage ranges from 200mV to 200V are available
  • Cur and voltage range settings define the maximum source or sink voltage or cur
  • Can be located at the signal source to minimize cable noise
  • Makes low cur sensitivity useful by eliminating long input cables
  • Is an integral part of this sourcemeter’s feedback measuring system that cannot be operated independently from the measurement mainframe, although it can be separated from the mainframe by up to two meters of connection cable carrying high level signals
