Low-current sourcing is critical to applications in test environments ranging from R\u0026amp;D to production, especially in the semiconductor, nanotechnology, and superconductor industries. High sourcing accuracy and built-in control functions make the 6221 ideal for applications such as Hall measurements, resistance measurements in delta mode, pulsed measurements, and differential conductance measurements.\u003c\/p\u003e\n\u003cp\u003eDevice testing and characterization for today’s very small and power-efficient electronics require sourcing low current levels, which demands a precision, low-current source. Lower stimulus currents produce lower, and harder-to-measure, voltages across the device. Combining the Model 6221 with a Model 2182A Nanovoltmeter makes it possible to address both of these challenges . AC current source and current source waveform generator. The Model 6221 is the only low-current AC source on the market. Before its introduction, researchers and engineers were forced to build their own AC current sources. This cost-effective source provides better accuracy, consistency, reliability, and robustness than “home-made” solutions. The Model 6221 is also the only commercially available current source waveform generator, which greatly simplifies creating and outputting complex waveforms \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCurrent Range: ±100 fA to 100 mA\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eResistance: \u003cspan\u003e10 nΩ to 200 MΩ (requires 2182A)\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e1014 W output impedance ensures stable current sourcing into variable loads\u003c\/li\u003e\n\u003cli\u003eSource AC currents from 4 pA to 210 mA peak-to-peak for AC characterization of components and materials.\u003c\/li\u003e\n\u003cli\u003eBuilt-in standard and arbitrary waveform generators with a 1 mHz to 100 kHz frequency range \u003cspan\u003ewith 10 M samples\/s output update rate.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eProgrammable pulse widths as short as 5µs, limiting power dissipation in delicate components. supports pulsed I-V measurements down to 50 µs when used with Model 2182a Nanovoltmeter\u003c\/li\u003e\n\u003cli\u003e65000-point source memory allows executing comprehensive test current sweeps directly from the current source\u003c\/li\u003e\n\u003cli\u003eReconfigurable triax output simplifies matching the application’s guarding requirements\u003c\/li\u003e\n\u003cli\u003eModel 220 emulation mode eliminates the need to reprogram existing applications\u003c\/li\u003e\n\u003cli\u003eBuilt-in Ethernet, RS-232, GPIB, Trigger link, and digital I\/O interfaces\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 100 Vac to 240 Vac rms, 50 to 60 Hz (automatically detected at power up).\u003c\/li\u003e\n\u003cli\u003eDimensions: 89 mm (H) x 213 mm (W) x 370 mm (D), Weight: 4.1 kg (9 lbs.)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlease see the Datasheet for complete details and specifications.\u003c\/p\u003e","brand":"Keithley","offers":[{"title":"Keithley 6221 AC and DC Current Source, 100 fA to 100 mA, GPIB, RS-232, Ethernet","offer_id":48948316864762,"sku":"KTH6221","price":7495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/3647\/8970\/files\/KTH6221-Front.jpg?v=1781370230","url":"https:\/\/www.bellnw.com\/products\/keithley-6221","provider":"Bell Electronics","version":"1.0","type":"link"}
