Used KEITHLEY 2420 #9308548 for sale

KEITHLEY 2420 is a versatile SourceMeter unit that combines the functionality of both a DC source (voltage/current) and a 6-1/2 digit DMM meter. The voltage/current source generates up to 20V/2A of voltage/current and the DMM supports measurements of voltage, current, and resistance with up to 6 1/2 digits of resolution. Furthermore, the device has multiple modes of operation, including sweep/list, dc transfer, and dc analysis. The sweep/list mode allows the user to scan through a set of points on a set of source/measure ranges. The dc transfer mode measures the change in voltage/current that occurs in response to set current/voltage source values. The dc analysis mode aids in testing digital circuits by offering ramp, pulse, and ESR (equivalent series resistance) tests. The device has several built-in protection features to maximize its lifespan and safety. This includes open-circuit protection for the current/voltage source outputs to protect against high voltages and currents on device connections, sample-and-hold protection to protect against unstable readings, and over-temperature protection for the DMM and current/voltage source. 2420 has a user-friendly graphical interface with a large color display and conveniently placed keys to make navigation and operation as simple and straightforward as possible. In addition to its physical features, the device runs the powerful, easy-to-use SCPI-compliant KEITHLEY 2400 Series Software Package, which provides an intuitive environment to create complex source/measure patterns. KEITHLEY 2420 is a tried and tested reliable device, making it an excellent choice for automated testing, college-level labs, industry, and research facilities. The device is an ideal tool for probing multiple parameters of a circuit in a single operation. In addition, 2420 is very affordable and is backed up by KEITHLEY world-class engineering and customer service support.
