Keithley 617 Programmable Electrometer

Product specifications of Keithley 617 (From Used-Line T&M Specifications)

  • Launch Date Jan-2049
  • Status Discontinued by Manufacturer

The Keithley 617 Programmable Electrometer is a highly sensitive instrument designed to measure voltage, current charge, and resistance. Two forms of resistance measurements are included in the standard configuration: a constant current method, and a constant voltage method that uses a built in voltage source for greater sensitivity. The measuring range of the Model 617 is between 10µV and 200V for voltage measurements, 0.1fA and 20mA in the current mode, 0.1Ω and 200GΩ (up to 1016Ω using the built in voltage source), and 10fC and 20nC in the coulombs mode. The very high input impedance and extremely low input offset current allow accurate measurement in situations where many other instruments would have detrimental effects on the circuit being measured. A 4½ digit display and standard IEEE-488 interface give the user easy access to instrument data.

  • Volts range: 200mV (10µV resolution) to 200V
    • NMRR: >80dB on 200mV
    • CMRR: >120dB
  • Amps range: 2pA (100aA resolution) to 20mA
    • Input bias current: <5fA
    • Input voltage burden: <1mV except 3mV on 20mA range
    • NMRR: >95dB on pA
  • Coulombs range: 200pC (10fC resolution) to 20nC; input bias current: <5fA 
  • Ohms range: 2kΩ (100mΩ resolution) to 200GΩ; maximum open circuit voltage: 300Vdc
  • 4½ Digit Display: An easy to read front panel LED display includes a 4½ digit mantissa plus a two-digit alpha or numeric exponent
  • Autoranging: Included for all functions and ranges
  • Digital Calibration: The instrument may be digitally calibrated from the front panel or over the IEEE-488 bus
  • Zero Correct: A front panel zero correct control allows the user to cancel any offsets
  • Baseline Suppression: One button suppression of a baseline reading is available from the front panel or over the IEEE-488 bus
  • One-shot Triggering: A front panel control for triggering one-shot readings from the front panel is included
  • Isolated 100V Voltage Source: A built in 100V source is isolated from the electrometer section. The voltage source is programmable in 50mV steps
  • Selectable Guarding: A selectable driven cable guard is included to optimize speed
  • Standard IEEE-488 Interface: The interface allows full bus programmable operation of the Model 617
  • Analog Outputs: Both preamp and 2V full range analog outputs are included on the rear panel
  • 100-Point Data Store: An internal buffer that can store up to 100 readings is accessible from either the front panel or over the IEEE-488 bus
