National Instruments PXI-2548 PXI RF Relay Module

The National Instruments PXI-2548 (Part number: 778572-48) is a General-Purpose Switching Module that has single-pole and double-throw, independent relays (SPDT). The NI PXI-2548 Switching Module reproduces the conduct of resistance‐based gadgets by controlling a progression of relays that varies resistance over each channel. The capacity to rapidly and precisely fluctuate resistance, with resolution down to 0.25 Ω, makes this gadget well‐suited for reenacting environmental conditions in hardware‐in‐the‐loop (HIL) approval. Each PXI Programmable Resistor Module utilizes a 37‐ pin D‐SUB connector on the front board to give access to all channels and additionally has a 2x2 Micro‐Fit connector for simple association with a PXI Digital Multimeter (DMM). The driver software gives a basic UI that acknowledges inputs to units of temperature or resistance and configures the resistance over each channel, without expecting to specifically control individual relays.

On the NI PXI-2548, programmable resistors are test modules that imitate the conduct of resistance-based information sources and outputs, including: potentiometers, RTDs, voltage dividers, and bridge elements. The total resistance over each channel, estimated over the front connector terminals, is controlled by manipulating the circuit path resistance by utilizing relays to specifically route through discrete resistors. PXI Programmable Resistor Modules automatically control the estimations of resistance showing up through an I/O connector, empowering utilization in HIL approval, which performs fast framework tests amid an assortment of simulated framework conditions.

This model offers 2.7 GHz of bandwidth, Insertion loss at 2.7 GHz <1.0 dB (typical <0.7 dB), VSWR at 2.7 GHz <1.7 (typical <1.5) and onboard relay counting.
