Keithley 224
Programmable Current Source 5nA-100mA,105V
Description
The Programmable Current Source was designed for general purpose bench or system use.
The INCREMENT/ DECREMENT function is manual or automatic, and selectable dwell times provide stepped ramp capabilities.
It allows flexible programming including current, V-LIMIT, local lockout, service request masks, and serial polling.
A digital I/O port on the IEEE-488 interface card provides four TTL compatible input and output lines.
The status of the I/O port can be interrogated and changed over the bus.
