SCXI-1193 多路复用开关模块

SCXI-1193是一款高密度、32通道RF多路复用器开关模块，零件号为776572-93，由National Instruments（NI）生产。它具有高度的配置灵活性，可以被配置为未端接多路复用器、外部端接多路复用器或尺寸多样的稀疏矩阵。每种配置都能承受从DC到500 MHz以上的信号频率。

该模块设计有一个插槽，并利用高密度推进式MCX连接器进行离散但易于管理的布线。然而，SCXI-1193模块不能将信号导向高压模拟总线。

SCXI-1193的通路电阻是继电器触点电阻和迹线电阻的组合，通常在继电器的寿命内保持较低。当继电器寿命结束时，触点电阻会迅速上升。此外，该模块的最大射频载功率为10W至500MHz（每个通道），但模块负载减额插入损耗可能导致模块内的功率耗散和热量积聚。因此，使用时需要根据图形图表确定每个有源通道中耗散的最大功率，并确保总射频功率耗散极限不超过7瓦。

SCXI-1193模块主要用于集成高频设备，如PXI-5404频率发生器和PXI-5112高速数字化仪。其高度灵活的配置选项和宽频率范围使其成为工业自动化和测试测量应用中的理想选择。然而，对于电磁兼容性（EMC）的声明和认证，用户需要查阅在线产品认证部分以获取更多信息。

如需更多关于SCXI-1193的技术规格、应用场景、使用方法或与其他设备的兼容性信息，建议查阅National Instruments的官方文档或联系其技术支持团队。同时，在购买和使用该模块时，也请确保遵循相关的安全规定和操作规程。

The SCXI-1193 is a high-density, 32-channel RF multiplexer switch module, part number 776572-93, manufactured by National Instruments (NI). It has a high degree of configuration flexibility and can be configured as an unterminated multiplexer, an externally terminated multiplexer, or a sparse matrix of various sizes. Each configuration can withstand signal frequencies from DC to more than 500 MHz.

The module is designed with a slot and utilizes high-density propulsive MCX connectors for discrete but manageable wiring. However, the SCXI-1193 module cannot direct the signal to a high-voltage analog bus.

The path resistance of the SCXI-1193 is a combination of relay contact resistance and trace resistance, which is usually kept low over the life of the relay. When the relay life ends, the contact resistance will rise rapidly. In addition, the module has a maximum RF load power of 10W to 500MHz (per channel), but module load derated insertion losses can lead to power dissipation and heat accumulation within the module. Therefore, it is necessary to determine the maximum power dissipated in each active channel according to the graphic diagram, and ensure that the total RF power dissipation limit does not exceed 7 watts.

The SCXI-1193 module is mainly used to integrate high frequency devices such as the PXI-5404 frequency generator and the PXI-5112 high-speed digitizer. Its highly flexible configuration options and wide frequency range make it ideal for industrial automation and test and measurement applications. However, for electromagnetic compatibility (EMC) claims and certifications, users need to consult the online Product Certification section for more information.

For more information about SCXI-1193’s technical specifications, application scenarios, usage methods, or compatibility with other devices, you are advised to consult the official documentation of National Instruments or contact its technical support team. At the same time, when purchasing and using the module, please also ensure that the relevant safety regulations and operating procedures are followed.
