Description
The NI PXI-2548 is a high-performance PXI Switch identified by the part number 196213J-01L (778572-48). This module is designed as a General-Purpose Switching Module that stands out for its exceptional capabilities in signal routing. It is specifically configured with Single-Pole Double-Throw (SPDT), Independent Relays, making it versatile for a variety of switching needs.
One of the key specifications of the PXI-2548 is its impressive 2.7 GHz bandwidth, which ensures minimal signal degradation over high frequencies. This is further complemented by an insertion loss at 2.7 GHz of less than 1.0 dB, typically less than 0.7 dB, ensuring high signal integrity. Additionally, the module maintains a Voltage Standing Wave Ratio (VSWR) at 2.7 GHz of less than 1.7, with typical values less than 1.5, which indicates a minimal signal reflection and a well-matched impedance.
The PXI-2548 boasts a resolution down to 0.25 Ω, allowing for precise control and measurement of signal paths. Connectivity is facilitated through a 37-pin D-SUB connector located on the front panel and 2×2 Micro-Fit connectors, providing flexible and reliable connections to external equipment. Furthermore, the module features onboard relay counting, which is a valuable tool for monitoring the health and usage of the relays to ensure reliable long-term operation.
In summary, the NI PXI-2548 is a robust solution for applications requiring high-frequency, general-purpose switching. Its combination of a high bandwidth, low insertion loss, and precise resolution make it an ideal choice for a wide range of signal routing tasks.
