Amplifier current gain can be matched to your experimental needs by selecting one of the three available dual resistive feedback probes, as the gain is partially determined by the value of the resistor in the headstage. There are three heastages to choose from: 1 G?/10 M?, 10 G?/10 M?, and 10 G?/100 M?. The wide range of feedback resistors means currents can be recorded with outputs of 1 mV/nA to 10 mV/fA. The standard probe sent with each unit is the 100 M>?/10 G>? version, but other values can be selected.
通过选择三种可用的双电阻反馈探头之一，放大器电流增益可以与您的实验需求相匹配，因为增益部分由头部电阻值决定。有三种等级可供选择：1 GΩ/10 MΩ、10 GΩ/10 MΩ 和 10 GΩ/100 MΩ。宽范围反馈电阻器意味着可以在 1 mV/nA 至 10 mV/fA 的输出下记录电流。每个单元随附的标准探头是 100 M>Ω/10 G>Ω 版本，但可以选择其他值。
Unlike other patch clamp amplifiers, the Model 2400 has a voltage follower in the probe. This allows this amplifier to be a true fast current clamp amplifier with no instability. An integrated four pole low pass Bessel filter provides flexible signal conditioning. Fine tuning capacity compensation is available to eliminate virtually all electrode-induced transients. Calibrated whole cell compensation provide easy display of membrane capacitance and access resistance.
与其他膜片钳放大器不同，2400 型在探头中有一个电压跟随器。这使得该放大器成为真正的快速电流钳位放大器，没有不稳定性。集成的 4 极点低通贝塞尔滤波器提供灵活的信号调节。微调容量补偿可用于消除几乎所有电极感应瞬变。校准的全池补偿可轻松显示膜电容和访问电阻。
A host of command potentials are integrated internally within the model 2400, including an automatic tracking command to zero the membrane current, manual controls for offset and holding potentials, and an easily readable digital display. For signals that are more complicated, an external command input with different scaling factors is available for use with any signal source. A digital meter provides accurate values of command signals and membrane currents or voltages, the true RMS noise of the amplifier and experimental setup, the cut off frequency of the low pass filter, and the overall gain of the amplifier plus probe.
2400 型内部集成了许多命令电位，包括将膜电流归零的自动跟踪命令、偏移和保持电位的手动控制以及易于读取的数字显示屏。对于更复杂的信号，具有不同比例因子的外部命令输入可用于任何信号源。数字仪表提供指令信号和膜电流或电压的准确值、放大器和实验装置的真 RMS 噪声、低通滤波器的截止频率以及放大器加探头的总增益。
Series resistance compensation provides the researcher with the option of introducing either or both predictive and corrective compensation from zero to 100%. Fine and coarse controls for lag provide sensitive control to minimize oscillation produced by compensation close to 100%. Separate compensation controls exist for eliminating transients seen during current clamp experiments when the bridge balance is used.
串联电阻补偿为研究人员提供了引入从 0 到 100% 的预测和校正补偿的一种或两种选择。滞后微调和粗略控制提供灵敏的控制，以最大限度地减少补偿产生的振荡接近 100%。存在单独的补偿控制，用于消除使用电桥平衡时电流钳位实验中出现的瞬变。
Telegraph outputs provide analog voltage equivalents of front panel settings including error conditions, amplifier mode and gain, Cmembrane, RMS noise, and low pass filter cut-off value. These telegraphs allow the Model 2400's front panel settings to be automatically recorded by your system software.
电报输出提供前面板设置的模拟电压等效值，包括误差条件、放大器模式和增益、Cmembrane、RMS 噪声和低通滤波器截止值。这些电报允许您的系统软件自动记录 2400 型的前面板设置。
