8-Channel IEPE Acceleration Data Acquisition System八通道 IEPE 加速度采集系统
A focused acquisition instrument for structural vibration, impact and modal testing. It removes general-purpose overhead while keeping the synchronized sampling, bandwidth, recording integrity and engineering workflow that serious acceleration measurement requires.面向结构振动、冲击与模态测试的专用采集设备。去掉与加速度测量无关的通用配置，同时完整保留同步采样、带宽、记录完整性和工程分析能力。
Focused on IEPE, Optimized for Cost, Uncompromised in Performance专注 IEPE，降低成本，不降低性能
Every input is designed around IEPE/ICP accelerometers. Eight channels are sampled at the same instant, so phase relationships, mode shapes and cross-channel response remain meaningful. The result is a compact instrument for projects that need dependable vibration data without paying for unused bridge, thermocouple or general-purpose conditioning.每个输入通道都围绕 IEPE/ICP 加速度传感器设计。八个通道在同一时刻采样，能够保留相位关系、振型和跨通道响应。对于只需要可靠振动数据的项目，无需为桥路、热电偶或其他未使用的调理功能增加成本。
- ✓Eight-channel phase-consistent acquisition八通道相位一致采集
One synchronized sample contains all eight channels, supporting structural response comparison and modal work.一个同步采样点包含全部八通道，适用于结构响应对比与模态分析。
- ✓Dedicated low-noise IEPE front end专用低噪声 IEPE 前端
Typical 4 mA constant-current excitation and fixed AC coupling are built around acceleration measurement.典型 4 mA 恒流激励与固定交流耦合均围绕加速度测量优化。
- ✓No silent sample loss不静默丢样
Frame gaps, buffer pressure and transfer faults are reported explicitly so incomplete records are not mistaken for valid tests.帧缺口、缓冲压力和传输异常均明确报告，避免把不完整文件误判为有效试验。
From Accelerometer to Traceable Engineering Data从加速度传感器到可追溯工程数据
Input, conditioning, synchronous conversion, recording and engineering-unit conversion are managed as one acquisition path.输入、调理、同步转换、记录与工程单位换算按照一条完整采集链管理。
