Used KEITHLEY 237 #9002615 for sale

KEITHLEY 237 is a high performance, cost-effective source measurement unit (SMU) designed for high precision testing of diodes, transistors, and other semiconductor devices. It is particularly suited for use in production applications, system operation, and research characterization. The instrument was engineered to deliver performance and accuracy with an intuitive user interface that simplifies the entire measurement process. The instrument comprises a number of basic sections. A controller/power supply section provides the interface and power for the instrument. It provides two 0-30V ranges and dual 0-2V limit ranges. It also has a low noise overhead adjuster for fine-tuning the output levels and a pair of front-panel measurement knobs for manual adjustments to the source level. A DC and AC source/measure section allows the user to set up and execute up to four DC or AC source scenarios. A range adjuster is available for adjusting the desired voltage range, and a pulse generator can be used to generate pulse patterns of any section. A six-digit voltmeter is available for displaying readback measurements. The source/measure section also features a built-in offset null to minimize errors from ground shifts and other effects. The main purpose of 237 is to accurately measure electrical characteristics of components and systems. An integrated Dual Channel Resistance meter allows the user to measure resistance values of low-resistance components in the milli-ohms range. The instrument also has the ability to measure currents in the micro-amp and nano-amp range, which makes it ideal for applications where low-level leakage testing and circuit characterization is required. KEITHLEY 237 contains a variety of hardware and software features that enables users to maximize the instrument's performance. A range of measurement functions, including current or voltage sourcing and instrument memory means that you can store and recall complex testing configurations. An optional internal temperature-controlled source provides additional control to match the exact limits of the device being tested.GPIB, RS-232, and Ethernet interfaces are available to provide communication and control of the instrument from external computers. Overall, 237 is an invaluable piece of equipment for electrical system testing and instrument control, and is backed up by a comprehensive software package that allows users to customize settings, automate testing, analyze results, and create comprehensive report summaries of device performance. Its features provide accuracy and expandability for the benchtop environment.
