【产品详情】

特征：

• 高带宽

• 单刀双掷

• 可变带宽

SCXI-1190/1191模块是通用的四通道4通道高带宽多路复用开关。SCXI-1192模块是一款通用的8通道SPDT高带宽继电器模块。型号为SCXI-1190之四通道4路多路复用转换器，拥有出色的功能与性能。此设备能够精准地在DC至1.3GHz间的频率范围内切换不同的信号流。无论是传输电压还是电流，该设备均能承载高达24V的上限并在面对24V压力下仍表现出杰出的1A额定电流表现。利用NI-SWITCH则可在此设备于应用开发过程中进行绝对控制。现如今，成熟的应用开发环境解决方案已得到完全兼容，无论您是采用C语言或者C++编程，还是选择使用LabVIEW、Visual Basic或者LabWindows/CVI等工具，均能无缝兼容应用。

相较于市面上其他的多路复用转换器，SCXI-1190独特之处在于它采用了反向操作的策略，因此那些未能成功切换至公共通道的通道便成为了未端接通道。这时将有任何信号从源处经过未端接通道时都会被设法反射回来。而这种行为，虽然对大多数低功耗开关应用来说并不构成负担，但若过度使用，可能会对某些高功率RF源带来损坏风险。

在我们的设计理念中，确保客户满意度始终位于首要位置。因此，我们在保证设备拥有极高的性能和稳定性的前提下，也特别重视设备的使用寿命和安全性。其中，在SCXI-1190设备的继电器触点的使用过程中，我们选用了5×10至6次功率机械操作的额定使用寿命标准。然而，需要注意的是，如果在电机切换较大功率负载的环节中，继电器触点可能出现因磨损引起的电弧现象，从而导致其长寿性受到影响。

为了提供给用户优质的产品与服务体验，SCXI-1190转换器模块搭载了四组每个组别具五个SMB公连接器的设备、具备50欧姆特性阻抗，还特设了镀金银的继电器触点设计。每通道最大开关功率设定为24W；开关速度不到300ps；信号延迟不超过3ns；继电器操作和释放时间不超过15ms。此外，每个通道拥有的900MHz时最大射频承载功率可达到10W，以应对各种高级应用需求。

The SCXI-1190/1191 module is a general purpose four-channel 4-channel high bandwidth multiplexing switch. SCXI-1192 module is a general purpose 8 channel SPDT high bandwidth relay module. Model SCXI-1190 four-channel 4-way multiplexer with excellent features and performance. The device can accurately switch between different signal streams in the frequency range from DC to 1.3GHz. In both transmission voltage and current, the device can carry up to 24V and still show outstanding 1A rated current performance in the face of 24V pressure. With NI-SWITCH, you can have absolute control over the device during application development. Today, mature application development environment solutions are fully compatible, whether you program in C or C++, or choose to use tools such as LabVIEW, Visual Basic, or LabWindows/CVI.

Compared to other multiplexers on the market, the SCXI-1190 is unique in that it uses a reverse operation strategy, so those channels that do not successfully switch to the public channel become disconnected channels. At this time, any signal that passes through the unconnected channel from the source will be reflected back. This behavior, while not burdensome for most low-power switching applications, can pose a risk of damage to some high-power RF sources if overused.

In our design philosophy, customer satisfaction is always at the forefront. Therefore, we pay special attention to the service life and safety of the equipment under the premise of ensuring the equipment has extremely high performance and stability. Among them, in the use of the relay contacts of the SCXI-1190 equipment, we selected the rated service life standard of 5×10 to 6 power mechanical operations. However, it should be noted that if the motor switches a higher power load, the relay contact may appear arcing due to wear, resulting in its longevity affected.

In order to provide users with a superior product and service experience, the SCXI-1190 converter module is equipped with four sets of devices with five SMB male connectors each, a 50 ohm characteristic impedance, and a gold plated silver relay contact design. The maximum switching power per channel is set to 24W; The switching speed is less than 300ps; The signal delay does not exceed 3ns; Relay operation and release time does not exceed 15ms. In addition, each channel has a maximum RF carrying power of 10W at 900MHz to meet the needs of various advanced applications.
