Description
The Part Number 778572-94 identifies a specific model within the Category of PXI Switches, known as the Model PXI-2594. This device is described as a 2.5 GHz 4 x 1 Multiplexer, designed to operate within a Frequency Range from DC up to 2.5 GHz. It is built to handle a Characteristic Impedance of 50 Ohms, ensuring compatibility with standard RF systems.
The Maximum Voltage Rating for this multiplexer is specified as 30 Vrms, with a Maximum Switching Current of 500 mA. While specific Insertion Loss values are recommended to be reviewed based on the intended application bandwidth, the device is noted for its Excellent VSWR (Voltage Standing Wave Ratio) performance. This indicates a minimal mismatch of impedance, which is crucial for maintaining signal integrity across the frequency spectrum it operates in.
In terms of isolation, the device achieves High levels, which is essential for preventing signal leakage between channels and ensuring accurate signal routing within complex test setups. The feature of Relay Count Tracking is supported, which can be invaluable for maintenance and diagnostic purposes, facilitating the monitoring of relay usage and predicting end-of-life scenarios.
The overall Path Resistance is determined by the sum of contact resistance and trace resistance, which are critical parameters for understanding the signal attenuation and power loss within the switch. Additionally, the Minimum Recognizable Trigger Pulse Width is specified as less than 150ns when digital filtering is disabled, highlighting the switch’s capability to respond to rapid signal changes, making it suitable for high-speed digital applications.
