{"product_id":"national-instruments-pxi-2548","title":"National Instruments PXI-2548","description":"\u003cp\u003eThe National Instruments PXI-2548 PXI RF Relay Module (Part Number: 778572-48) is a versatile general-purpose switching module designed for demanding applications requiring precise control of resistance-based devices. This module features single-pole double-throw (SPDT) independent relays that allow for accurate modulation of resistance across each channel, with a resolution of 0.25 Ω. It is optimized for hardware-in-the-loop (HIL) validation, enabling rapid and reliable simulations of environmental conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe PXI-2548 integrates a 37-pin D-SUB connector on the front panel to facilitate access to all channels and includes a 2x2 Micro-Fit connector for straightforward interfacing with PXI Digital Multimeters (DMM). The accompanying driver software provides a user-friendly interface that permits configuration of resistance values in temperature or resistance units without the need to manually manage individual relays. It effectively emulates the behavior of various resistance-based inputs and outputs, including potentiometers, RTDs, voltage dividers, and bridge circuits.\u003c\/p\u003e\n\n\u003cp\u003eThis module boasts a switch bandwidth of 2.7 GHz with a typical insertion loss of less than 0.7 dB and a voltage standing wave ratio (VSWR) of less than 1.5, ensuring optimal performance in high-frequency applications. The PXI-2548's design is compact, measuring 8.5 x 0.8 x 5.1 inches and weighing 9 ounces, making it suitable for diverse test environments. For comprehensive information, user and maintenance manuals are available for download.
