Keithley 超低电阻配置
  • Keithley 超低电阻配置
  • 适用于超低电阻测量的两个选项 连接时,2182A 型和 6220 或 6221 型可以如同一台仪器一样运行。2182A/622X 组合是电阻测量、脉冲式 I-V 测量和微分电导测量的理想工具,比其他解决方案具有更显著的优势。2182A/622X 组合也非常适合许多纳米技术应用,因为它测量电阻时可以不消耗被测器件 (DUT) 的太多功率,否则可能会导致结果无效,甚至损坏 DUT。

Title Document Type
Keithley Instrumentation for Electrochemical Test Methods and Applications This Application Note discusses electrochemistry disciplines in which Keithley instrumentation is used. 应用指南
Achieving Accurate and Reliable Resistance Measurements in Low Power and Low Voltage Applications There are many factors that make low voltage measurements difficult. This paper discusses techniques to eliminate thermoelectric voltages to allow more accurate resistance measurements, including a three-step delta measurement method for low power/low voltage applications. 白皮书
New Instruments Can Lock Out Lock-ins With modern instruments like the Keithley 6220 Current Source and 2182A Nanovoltmeter, the DC reversal method requires less power while providing excellent low-noise results. This combination is optimal for low frequencies (0.1–24Hz,) allowing measurements to be made much faster than with a lock-in amplifier. 白皮书
An Improved Method for Differential Conductance Measurements Keithley''s approach to differential conductance, a four-wire, source current/measure voltage technique, uses the 6220 and 6221 Current Sources and 2182A Nanovoltmeter. The current sources combine the DC and AC components into one source, with no need to do a secondary measure of the current, because its output is much less dependent on the changing device impedance 白皮书
