National Instruments SCXI-1530 声音和振动输入模块
SCXI-1530(部件号:777966-30)是一款信号调理模块,专为集成电子压电(IEPE)加速度计和麦克风而设计。该模块可与加速度计调理模块配合使用,该模块在每个通道上集成了可编程电流、增益和滤波器配置。NI SCXI-1530 包括 4 个 输入 通道、 1 MΩ 的 放大器 输入 阻抗 、 交流 功放 耦合、 4 mA +/-10% 的 加速度 计 输入 激励 电流、 超过 400 KΩ 的 电流 源 炸药 阻抗、 +/- 10 V 最大 输出 电压 和 200 Ω 的 输出 阻抗。
在SCXI-1530声音和振动输入模块上,加速度计由电流源激励。用户可以削弱电流源,以量化框架中的噪声。还有一个接地开关,用户可以通过软件打开或关闭,以适应接地参考和非参考加速度计。升压信号与可编程增益仪表增强器交流耦合。该增强器通过增益 1、10 或 100 来帮助输入信号。接下来,信号通过可编程数据传输容量的低通贝塞尔滤波器,以减少混叠。同步采样保持电路确保所有通道都以相似的时刻为基准。最后,将调理信号发送到多路复用器电路和背面连接器,以改善信号关联。

【英文介绍】
National Instruments SCXI-1530 Sound and vibration input module
The SCXI-1530 (Part number: 777966-30) is a signal conditioning module designed for integrated electronic piezoelectric (IEPE) accelerometers and microphones. The module can be used in conjunction with the accelerometer conditioning module, which integrates programmable current, gain and filter configurations on each channel. The NI SCXI-1530 includes 4 input channels, 1 MΩ amplifier input impedance, AC power amplifier coupling, 4 mA +/-10% accelerometer input excitation current, over 400 KΩ current source explosive impedance, +/-10 V Maximum output voltage and 200Ω output impedance.
On the SCXI-1530 sound and vibration input module, the accelerometer is stimulated by a current source. Users can weaken the current source to quantify the noise in the frame. There is also a ground switch that can be turned on or off by the user through software to accommodate ground reference and non-reference accelerometers. The boost signal is AC coupled to a programmable gain meter intensifier. The enhancer assists the input signal by gaining 1, 10, or 100. Next, the signal passes through a programmable data transmission capacity low-pass Bessel filter to reduce aliasing. The synchronous sampling hold circuit ensures that all channels are benchmarked at similar moments. Finally, the conditioning signal is sent to the multiplexer circuit and back connector to improve signal correlation.
