Keithley Model 220 Programmable Current Source

Keithley Model 220 Programmable Current Source

The Model 220 Current Source is an economical, programmable solution for precision sourcing of DC current. Constant current sources are needed when a device or material is best characterized by controlling the current through it, rather than the voltage across it.

Features:

• ±0.5pA to ±101mA DC output
• 1014Ω output resistance
• ±1V to ±105V programmable V-LIMIT
• Hardware Trigger IN/OUT
• IEEE-488 (GPIB)
• 100-point source memory
• Programmable Digital I/O
