National Instruments PXI-2546 PXI RF Multiplexer Switch Module

The National Instruments PXI-2546 (Part Number: 778572-46) is an RF Signal Multiplexer Switching Module. In numerous loop hardware test systems (HIL), hardware fault insertion or signal insertion is utilized to make signal failures between the electronic control unit (ECU) and whatever remains of the framework to test, characterize, or approve the conduct of the ECU under specific failure conditions. Fault insertion is more typically used when it is important that a certain ECU has a known and satisfactory reaction to the failure conditions; examples incorporate ECU for vehicles, aircraft, spacecraft, and machinery. To accomplish this, Fault Insertion Units (FIU) are embedded between the I/O interfaces of a test framework and the ECU, so the test framework can switch between ordinary activity and failure conditions, such as a short circuit to the battery, short to Earth, or open circuit.

The PXI-2546 offers many highlights, such as hardware activating, locally available relay count tracking, and a wide assortment of reconfigurable models, giving the user the alternative to adjust the topology of the switch for their requirements. These propelled highlights offer a more astute approach to handle troublesome applications in enterprises ranging from consumer electronics to aviation and defense.

This model offers 2.7 GHz of transmission capacity, insertion loss at at 2.7 GHz <1.35 dB (ordinary <1.05 dB), VSWR at 2.7 GHz <1.7 (ordinary <1.5), onboard relay counting, and incorporates the NI Switch Executive for aligning losses on each channel of the PXI-2546 Multiplexer Switch Module.
