Product Description:
Keithley Instruments Inc. 220 1nA-100mA, Programmable Current Source
Feature:No. of outputs: 1o/p
The demand on researchers, designers, and evaluation engineers for better device characterization has generated a widespread need for programmable, low-level DC sources. And, as an experienced manufacturer of automatic wafer measuring equipment, Keithley knows the importance to the user of instrument compatibility and ease of system integration. In system applications, the buffer can be loaded through the bus and the 220 or 230 can be commanded to sequence through memory while the controller is busy on other tasks. In a typical application, a source can be programmed to generate an SRQ (service request) to the controller if a system element such as a foot pedal switch, mechanical stop, or over-temperature condition is detected. The 230-1 is a special version of the 230 with the necessary connectors for compatibility with the Model 82 Simultaneous C-V Systems.The demand on researchers, designers, and evaluation engineers for better device characterization has generated a widespread need for programmable, low-level DC sources.
