6430：Sub-femtoamp Remote SourceMeter SMU Instrument

KEITHLEY静电计6430产品介绍

The Model 6430 Sub-Femtoamp Remote SourceMeter SMU Instrument combines the voltage and current sourcing and measurement functions of Keithley’s popular SourceMeter SMU instruments with sensitivity, noise, and input resistance specifications superior to electrometers. This unique combination of broad functionality and exceptional measurement integrity is made possible by the Model 6430’s Remote PreAmp, which offers a very sensitive bi-directional amplifier with sensitive feedback elements for measuring or sourcing currents at the device being tested. The high level signals output by the Remote PreAmp are sent to the controlling mainframe via a two-meter cable. This allows the user to make a direct or very short connection to the signal, minimizing the effects of cable noise.

The Model 6430 makes voltage, current, and resistance measurements at speeds no electrometer can match. It can read up to 2000 source/ measure readings per second into internal memory. Currents can be measured in as little as 5ms on the 100nA range, decreasing to just a few hundred microseconds on the higher ranges.

The Model 6430’s distinguishing features include its excellent low current sensitivity and the Remote PreAmp, which makes this sensitivity useful by eliminating long input cables. The Remote PreAmp is an integral part of the Model 6430’s feedback measuring system that cannot be operated independently from the measurement mainframe, although it can be separated from the mainframe by up to two meters of connection cable carrying high level signals

6430 型远程源表 SMU 仪器将广受欢迎的源表 SMU 仪器的电压和电流源及测量功能与优于静电计的灵敏度、噪声和输入电阻规格相结合。 6430 型的远程前置放大器使这种广泛的功能和卓越的测量完整性的独特组合成为可能，它提供了一个非常灵敏的双向放大器，带有灵敏的反馈元件，用于测量或在被测设备上提供电流。 远程前置放大器输出的高电平信号通过两米长的电缆发送到控制主机。 这允许用户与信号建立直接或非常短的连接，从而最大限度地减少电缆噪声的影响。

6430 型以静电计无法比拟的速度进行电压、电流和电阻测量。 它每秒可将多达 2000个测量读数读入内存。 在 100nA 范围内，电流测量时间短至 5 毫秒，在更高范围内，测量时间缩短至几百微秒。

6430 型的显着特点包括出色的低电流灵敏度和远程前置放大器，通过长输入电缆，使这种灵敏度变得有用。 远程前置放大器是 6430 型反馈测量系统的一个组成部分，虽然可以通过长达两米的传输高电平信号的连接电缆将其与主机分开，但不能独立于测量主机进行操作
