National Instruments PXI-2558 PXI RF Relay Module
The National Instruments PXI-2558 (Part Number: 778572-58) is a broadly useful single-pole double-throw (SPDT) switch module. This PXI RF Relay Module can be utilized to add adaptability to a video switch network or to keep up uniform signal paths over various channels when assembling high-channel-count multiplexers. An ideal switch has a VSWR equivalent to 1. In any case, much of the time, a switch that has a VSWR of 1.8 or less at the frequency of the signal being routed is adequate to keep the source from being harmed. A switch transfer speed is not identified with its VSWR detail, which is the reason that the VSWR execution of the item at the frequency of interest of the user’s application addresses framework issues. While deciding the best switch to use in an RF application, topology and data transfer capacity are normally imperative contemplations.
To use the National Instruments PXI-2558 Switch Network, the user should follow these steps:
1. Check whether insertion loss and VSWR specifications of a specific RF switch at the frequency of the user’s application are in accordance with the necessities of the framework.
2. Try to abstain from cascading multiplexers when conceivable by utilizing items that give inalienable topologies. When inalienable topologies are inaccessible, then utilize SPDT transfers and multiplexers to guarantee that the signal path length for all channels in the user’s framework is the same to maintain a strategic distance from disparities in estimations between channels.
