As a 2.7 GHz, 50 \u03a9, terminated 4×1 PXI RF multiplexer switch module<\/strong>, the NI PXI-2545 allows users to route RF signals between one common port and four channels while maintaining controlled impedance and minimizing signal degradation. NI lists the PXI-2545 with part number 778572-45<\/strong>.<\/p>\n

\u0417\u0435\u043c\u043b\u044f NI PXI-2545<\/strong> is useful for engineers who need to switch RF signals in automated test systems. It can be used to route signals between RF sources, analyzers, devices under test, antennas, filters, amplifiers, and other RF components. Compared with manual RF switching, the PXI-2545 allows switching paths to be controlled through software, making it suitable for repeatable test sequences, production validation, and laboratory automation.<\/p>\n
