Keithley Instruments Inc. 6221-2182A DELTA MODE SYSTEM
The Keithley 6221-2182A Delta Mode System combines the Model 6221 AC and DC Current Source with the Model 2182A Nanovoltmeter to provide a low noise, high precision solution for measuring low-level resistance and performing delta mode measurements. This system is designed for applications requiring sensitive current sourcing and nanovolt-level voltage measurements, such as characterizing superconductors, nanomaterials, and low-resistance devices. The Delta Mode technique minimizes the effects of thermal EMFs and noise, enabling accurate and repeatable measurements. The 6221-2182A system supports automated measurements, fast data acquisition, and is compatible with Keithleys software tools for streamlined operation.
