The Model 2401 also offers an economical alternative for applications for which precision programmable power supplies cannot deliver sufficient accuracy, signal range, source setting, or readback resolution.\u003cbr\u003e\u003cbr\u003eThe Model 2401 offers users all the same accuracy, speed, and measurement functions as the rest of the instruments in the Series 2400 family. It shares a common operating code base with the rest of the family, so it can be operated and programmed within its range boundaries just like any other Series 2400 instrument. The only functional differences between the Model 2401 and the Model 2400 are that the Model 2401 does not include 200V source and measure ranges or back panel Digital I\/O port capabilities. (However, the DB-9 connector is still provided to provide test fixture interlock signals.)\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e1μV–20V and 10pA–1A precision voltage and current sourcing and measurement capabilities\u003cbr\u003eFive instruments in one (IV Source, IVR Measure)\u003cbr\u003eSource and sink (4-quadrant) operation\u003cbr\u003e0.012% basic measure accuracy with 5½-digit resolution\u003cbr\u003e2-, 4-, and 6-wire remote V-source and measure sensing\u003cbr\u003e1700 readings\/second at 4½ digits via GPIB\u003cbr\u003eStandard SCPI GPIB, RS-232 and Keithley Trigger Link interfaces\u003cbr\u003eKeithley LabTracer 2.0 I-V curve tracing application software\u003cbr\u003eTypical Applications\u003cbr\u003e\u003cbr\u003eHigh brightness LED (DC and pulse)\u003cbr\u003ePhotovoltaic cell efficiency (source and sink)\u003cbr\u003ePrecision DC power supply\/ current measure\u003cbr\u003eDiscrete semiconductor devices\u003cbr\u003ePassive devices\u003cbr\u003eLaser diodes, laser diode modules, LEDs, photodetectors\u003cbr\u003eConnectors, switches, relays\u003cbr\u003eLow voltages\/resistances\u003cbr\u003eLIV\u003cbr\u003eIDDQ\u003cbr\u003eI-V characterization\u003cbr\u003e\u003cbr\u003eThe economical Model 2401 is the latest member of Keithley’s Series 2400 SourceMeter family, designed specifically for low voltage test applications that demand tightly coupled sourcing and measurement. Like all Series 2400 SourceMeter models, the Model 2401 provides precision voltage and current sourcing and measurement capabilities (1μV–20V and 10pA–1A). It is both a highly stable DC power source and a true instrument-grade 5½-digit multimeter.\u003cbr\u003e\u003cbr\u003eThe power source characteristics include low noise, precision, and readback. The multimeter capabilities include high repeatability and low noise. The result is a compact, single-channel, DC parametric tester. In operation, it can act as a voltage source, a current source, a voltage meter, a current meter, and an ohmmeter.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Keithley","offers":[{"title":"Default Title","offer_id":41497369313458,"sku":"","price":2995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0247\/3751\/3562\/files\/COG01868.jpg?v=1787898489","url":"https:\/\/cogwell.com\/products\/keithley-2401-source-meter-current-resistance-voltage-measure-current-voltage-source-20-w","provider":"COGWELL","version":"1.0","type":"link"}
