Description
The product with the part number 778572-48 falls under the category of PXI Switches. Specifically, it is identified as model PXI-2548. This model is described as 2.7 GHz 50 Ohm Quad SPDT Relays, indicating its high-frequency performance and the specific impedance it is designed to work with. It serves as a General-Purpose Switching Module, making it versatile for various applications.
The configuration of this model is characterized as Single-pole, double-throw (SPDT), independent relays. This configuration indicates that each relay can connect one input terminal to one of two output terminals. The resistance resolution of this module can go down to 0.25 Ω, allowing for precise control over resistance values in the system. It utilizes a 37-pin D-SUB (front panel), 2×2 Micro-Fit connector type, providing reliable and convenient physical connections for signal routing.
The bandwidth capability of the PXI-2548 reaches up to 2.7 GHz, ensuring it can handle high-frequency signals effectively. The insertion loss at this frequency is < 1.0 dB (Typical < 0.7 dB), indicating a minimal reduction in signal strength through the switch. Furthermore, the Voltage Standing Wave Ratio (VSWR) at 2.7 GHz is < 1.7 (Typical < 1.5), which measures the efficiency of the signal transmission and reflects a low reflection coefficient for high-frequency signals.
An additional feature of this model is its Onboard Relay Counting capability, which allows for the monitoring and maintenance of the relay’s usage, enhancing reliability and longevity of the module.
