Description
The Part Number 186676D-01 corresponds to a product in the PXI Switches category, specifically the model SCXI-1190. This device is described as a 1.3 GHz Quad, 4 to 1, 50 OHM Multiplexer, designed to operate within a frequency range from DC to 1.3 GHz. It can handle a maximum voltage of 24 V and a maximum current of 1 A at 24 V. The control interface is compatible with NI-SWITCH and supports programming in C/C++, LabVIEW, Visual Basic, and LabWindows/CVI.
This multiplexer is characterized by a Quad 4-Channel Multiplexing channel configuration, and it boasts a relay operation life of 5 × 106 mechanical operations. Connectivity is provided via five SMB male connectors per bank, ensuring compatibility with various setups. The characteristic impedance of this device is 50 Ohms, with relay contacts made of gold-clad silver to ensure reliability and durability.
Each channel of the SCXI-1190 can handle a maximum switching power of 24 W. The device features a rise time of less than 300 ps and a signal delay of less than 3 ns, ensuring quick response times for high-frequency applications. The relay operate and release time is specified at 15 ms, while the maximum RF carry power is 10 W at 900 MHz per channel, accommodating a wide range of RF applications.
It is important to note that this model has been announced as obsolete by National Instruments, but it remains available for purchase and repairs through Apex Waves. This ensures that users can continue to rely on
