KEITHLEY 6221/2182A/E. 源测量单元, 纳伏计, ± 100mV至± 40V, ± 2nA至± 100mA, 11 W
The Model 6221 combined with the Model 2182A, is the industry"s most complete solution for differential conductance measurements. Together, these instruments are also the fastest solution available, providing 10x the speed and significantly lower noise than other options. Data can be obtained in a single measurement pass, rather than by averaging the result of multiple sweeps, which is both time-consuming and prone to error. The Model 6221 and Model 2182A are also easy to use because the combination can be treated as a single instrument. Their simple connections eliminate the isolation and noise current problems that plague other solutions.
