The Keithley Model 237 Source-Measure Unit (SMU) is a fully programmable instrument, capable of sourcing and measuring voltage or current simultaneously. This system is really four instruments in one: voltage source, current source, voltage measure, and current measure.

This instrument addresses a wide variety of applications, including the characterization of semiconductor devices and the measurement of leakage currents or insulation resistance. It can be used standalone on a bench, in a test rack with PC control, or integrated with our Model 4200-SCS for high voltage semiconductor characterization.

The Model 237 will source voltage from 100µV to 1100V, and current from 100fA to 100mA. It can also measure voltage from 10µV to 110V and current from 10fA to 100mA. In the higher voltage range, current source and measure is 10mA maximum.

Related Applications:
• MOSFET measurements
• GaAs measurements
• Bipolar measurements
• Diode characterization
• Oxide characteristics
• Electromigration testing
• Research and electronic manufacturing applications

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
