National Instruments PXI-2541 PXI RF Matrix Switch Module

The National Instruments PXI-2541 (Part Number: 778572-41) is an RF Signal Switching Matrix that can be used for high channel applications and can associate numerous PXI-2541 modules together to make switching networks of 8x24, 8x36, and bigger. This model supports column development. Row Out connectors of one module can be associated with the Row-In connectors of another module to make bigger matrices. The impact of network development on R0C0 insertion loss is high when link part number 188374-0R15 is utilized to cascade 2, 4, 6, and 8 modules. VSWR for these cases stays underneath 1.8 past 300 MHz. As a relay actuates, the channel is immediately unterminated. Some RF sources can be harmed by reflections if their outputs are not legitimately ended.

Reed relays available with the NI PXI-2541 are exceedingly powerless to harm caused by switching capacitive and inductive loads. Capacitive loads can cause high inrush currents while inductive loads can cause high flyback voltages. The expansion of proper protection can incredibly enhance contact lifetime. Path resistance is a mix of relay contact resistance and trace resistance. Contact resistance commonly stays low for the life of a relay. Toward the end of relay life, the contact resistance transcends 3.1 Ω.

This model offers an 8x12 RF framework for directing signals up to 300 MHz, it is expandable to 8x24, 8x36, and bigger with numerous modules, RF execution at 300 MHz: insertion loss <2.1 dB, detachment >75 dB (typical), up to 60 V or 0.5 A, triggering by means of the PXI backplane.
