Broad Purpose Current Sources

  • Current range of 100fA to 100mA or 10pA to 1A
  • Low current noise
  • Stable current with up to 10^14 ohm output impedance
  • RS-232, GPIB, Trigger Link, digital I/O interfaces
  • Automated testing capability 
Combine ease of use with exceptionally low current noise
Tight control over sourcing can be critical in preventing self-heating that can damage the device or material being tested. Keithley current sources combine this tight control with precision, low current noise, and ease of use. These instruments are suitable for testing a wide variety of devices, including diodes, resistors, resistor networks, active circuit protection devices, and portable battery-powered devices and components
