The Model 2200 Analog Stimulus Isolator provides opto-electrical isolation, signal scaling, and conversion to constant current or constant voltage, for stimuli generated by your signal source. The output signal is DC-coupled, and can take on any waveshape within its wide bandwidth, including pulses.
2200 型模拟激励隔离器为信号源产生的激励提供光电隔离、信号缩放和转换为恒流或恒压。输出信号是直流耦合的，可以在其宽带宽内呈现任何波形，包括脉冲。
The input signal voltage, scaled according to the Range switch setting, can result in an output as large as 100 V (or ± 50V in bipolar mode), and ±5mA. The output signal can be turned on and off by a TTL level signal Control Gate. If for any reason the instrument cannot follow the input signal, an Error indicator lights alerting the user to the issue.
输入信号电压（根据范围开关设置进行缩放）可产生高达 100 V（或双极模式下± 50V）和 ±5mA 的输出。输出信号可以通过 TTL 电平信号 Control Gate 打开和关闭。如果由于任何原因仪器无法跟踪输入信号，则错误指示灯会亮起，提醒用户注意问题。
The isolated output section is battery-powered and optically-coupled to the input section, providing excellent isolation. Two rechargeable batteries are utilized: a 9V battery that powers the control circuitry, and a 12 V battery that provides the signal power.
隔离输出部分由电池供电，并与输入部分光耦合，提供出色的隔离。使用两节可充电电池：一节为控制电路供电的 9V 电池和一节提供信号电源的 12 V 电池。
Both rechargeable batteries provides full function for at least 8 hours of continuous use. During non-use periods, it is recommended that the unit remain on a trickle charge by connection to the provided external battery charger. An internal battery tester is provided. A charger is supplied, and an overnight charge cycle is all that is required to ready the 2200 for another day’s use.
两节充电电池均提供完整的功能，可连续使用至少 8 小时。在不使用期间，建议通过连接提供的外部电池充电器使设备保持涓流充电状态。提供内部电池测试仪。提供充电器，只需一个夜间充电周期即可为 2200 准备好改天使用。
Two units can be ganged together to increase the constant current or constant voltage ouput capacity. The digital control port enables remote On/Off operation, as well as remote sensing of the battery status.
两个单元可以联用在一起，以增加恒流或恒压输出能力。数字控制端口可实现远程开/关操作，以及电池状态的远程感应。
