超低電阻配置
- Keithley 超低電阻配置
- 適用于超低電阻測量的兩個選項 連接時，2182A 型和 6220 或 6221 型可以如同一臺儀器一樣運行。2182A/622X 組合是電阻測量、脈沖式 I-V 測量和微分電導測量的理想工具，比其他解決方案具有更顯著的優(yōu)勢。2182A/622X 組合也非常適合許多納米技術應用，因為它測量電阻時可以不消耗被測器件 (DUT) 的太多功率，否則可能會導致結(jié)果無效，甚至損壞 DUT。

| Keithley Instrumentation for Electrochemical Test Methods and Applications This Application Note discusses electrochemistry disciplines in which Keithley instrumentation is used. | 應用指南 |
| 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. | 白皮書 |

| 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. | 白皮書 |
| 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 | 白皮書 |
