产品概述：
SR570 是一款低噪声电流前置放大器，能够实现高达 1 pA/V 的电流增益。高增益和带宽、低噪声和许多方便的功能使 SR570 成为各种光子、低温和其他测量的理想选择。
产品特点：
两个后面板光电隔离 TTL 输入提供了对 SR570 的额外控制。消隐输入可让您快速关闭/打开乐器的增益，这对于防止前端过载非常有用。切换输入响应 TTL 信号反转增益符号，允许您使用斩波信号执行同步检测。
三节可充电铅酸电池可提供长达 15 小时的电池供电操作。当设备连接到线路时，内部电池充电器会自动为电池充电。充电器感应电池状态并相应地调整充电速率。两个后面板 LED 指示灯指示电池的充电状态。当电池放电时，它们会自动断开与放大器电路的连接，以避免损坏电池。

Product Overview:
The SR570 is a low noise current preamplifier capable of achieving current gains of up to 1 pA/V. High gain and bandwidth, low noise, and many convenient features make the SR570 ideal for a variety of photon, low temperature, and other measurements.
Product features:
Two rear panels optically isolated TTL inputs provide additional control over the SR570. The blanking input lets you quickly turn the instrument's gain off/on, which is useful for preventing front end overload. Switching the input in response to the TTL signal inversion gain symbol allows you to perform synchronous detection using the chopper signal.
Three rechargeable lead-acid batteries provide up to 15 hours of battery-operated operation. When the device is connected to the line, the internal battery charger automatically charges the battery. The charger senses the state of the battery and adjusts the charging rate accordingly. Two rear panel LED indicators indicate the battery's charging status. When the battery is discharged, they automatically disconnect from the amplifier circuit to avoid damaging the battery.
