这PXI-4461(零件号:779687-01)用于声音和振动应用。该模块提供双通道动态信号产生和双通道采集。六种增益设置之一可用于设计输入范围。这PXI 4461集成可编程配置的交流/DC耦合和IEPE调节。这倪PXI-4461整合了设备和编程，有望利用接收器、加速度计和具有较大动态范围的不同传感器进行精度估计。该模块的常见应用包括音频测试、汽车噪声、振动和粗糙度(NVH)以及机器状态监控。
这PXI 4461国家仪器模块支持AI的两种端子排列:差分和伪差分。伪差分一词暗指外部BNC外壳和机箱框架之间存在50ω电阻。该模块上的模拟输入通道也有数字滤波器，以防止出现混叠。用户可以安排PXI国家仪器公司NI-4461每个通道前提下的输入通道。因此，用户可以将一个通道配置为差分模式，另一个通道配置为伪差分模式。然后，用户可以根据信号源或被测设备(DUT)的参考方式来安排通道。
这倪PXI 4461 PXI声音和振动 模块的对于混合信号应用，采集时钟可以与用户系统中的其它器件同步。该模块提供数字和模拟触发功能。模拟输入通道具有24位分辨率模数转换器，可针对常规音频应用以软件可编程速率同时采样。例如，这些速率之一是CD播放器中使用的44.1 kS/s。另一个例子是48.0 kS/s，这是在数字音频磁带录音机和其他类型的数字音频设备中使用的速率。
PXI-4461
The PXI-4461 (Part Number: 779687-01) is intended for sound and vibration applications. This module gives two-channel dynamic signal generation and two-channel acquisition. One of six gain settings can be used to design the input range. The PXI 4461 incorporates programming configurable AC/DC coupling and IEPE conditioning. The NI PXI-4461 incorporates the equipment and programming expected to make accuracy estimations with receivers, accelerometers, and different transducers that have large dynamic ranges. Common applications for this module include audio test, automotive noise, vibration, and harshness (NVH), and machine condition monitoring.
The PXI 4461 National Instruments module supports two terminal arrangements for AI: differential and pseudo-differential. The term pseudo-differential alludes to the way that there is 50 Ω of resistance between the external BNC shell and chassis frame. The analog input channels on this module also have digital filters to stop aliasing from occurring. The user can arrange the National Instruments NI PXI-4461 input channels on a per channel premise. Therefore, the user can have one channel configured for differential mode and the other channel configured for pseudo-differential mode. Then, the user can arrange the channels in view of how the signal source or device under test (DUT) is referenced.
The NI PXI 4461 PXI Sound and Vibration Module’s acquisition clock can be synchronized with other devices in the user’s system for mixed-signal applications. Digital and analog triggering are features offered on this module. The analog input channels have 24-bit resolution analog-to-digital converters that are simultaneously sampled at software-programmable rates for regular audio applications. For example, one of these rates is 44.1 kS/s which is utilized in CD players. Another example is 48.0 kS/s which is the rate utilized in digital audio tape recorders and other types of digital audio devices.
