A relatively inexpensive solid state device designed for calibration of amplifiers and recorders used in microelectrode studies is described. The device is imposed between the ground electrode and the amplifier and provides three calibration signals; 100 mV DC for calibrating amplitude a variable-frequency square wave, 100 mV in amplitude use for capacitance neutralization, and a 100-mV, essentially square-wave signal with variable rate of rise and fall used for calibrating electronic differentiating circuits. The instrument is self-contained and battery powered. It was designed to remain in the circuit while recording. Calibration can be accomplished with the microelectrode in the circuit or with a dummy load.
本文描述了一种相对廉价的固态设备，该设备用于微电极研究中放大器和记录仪的校准。该设备置于接地电极和放大器之间，可提供三种校准信号：用于校准幅度的100 mV直流可变频率方波、用于电容中和的幅度为100 mV的信号以及用于校准电子微分电路的幅度为100 mV、上升和下降速率可变的基本方波信号。该仪器是独立的且由电池供电。其设计目的是在记录时保持在电路中。校准可在电路中的微电极或虚拟负载的情况下完成。
