Keithley 6430 亚fA程控源表

6430亚fA程控源表集合了Keithley源表产品和源测量单元(SMU)的电压电流源及测量功能，比静电计灵敏度更高，噪声更低，输入阻抗更高。这种的性能是通过6430远端前置放大器实现的，它提供非常灵敏的双向放大器，用于测量或产生被测试器件的电流。远端前置放大器输出的高层信号通过一条两米长的线缆发送到控制主机上。这使得用户可以直接，或者近距离连接该信号，减少线缆噪声的影响。

The 6430 sub-fA programmable source meter gathers the voltage and current sources and measurement functions of Keithley source meter products and source measurement units, which has higher sensitivity, lower noise and higher input impedance than the electrometer. This unique performance is achieved through the 6430 remote preamplifier, which provides a very sensitive bidirectional amplifier for measuring or generating the current of the device under test. The high-level signal from the remote preamplifier is transmitted to the control host through a two-meter-long cable. This allows the user to connect the signal directly, or at close range, to reduce cable noise.
